Accounting Policies [Abstract]
Accounting Policies and Basis of Presentation	Accounting Policies and Basis of Presentation:
	The accompanying consolidated financial statements have been prepared in conformity with the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") of accounting principles generally accepted in the United States of America ("GAAP"). These interim financial statements should be read in conjunction with these notes and those included in the Company's 2014 Annual Report on Form 10-K incorporated herein by reference.
	Pertinent accounting and disclosure pronouncements issued from time to time by the FASB are adopted by the Company as they become effective. In May 2014, the FASB issued a comprehensive revenue recognition standard which applies to all entities that have contracts with customers, except for those that fall within the scope of other standards, such as insurance contracts. The Company is currently evaluating the guidance, which is expected to be effective in 2018, to determine the potential impact, if any, of its adoption on its consolidated financial statements.
	The financial accounting and reporting process relies on estimates and on the exercise of judgment. In the opinion of management all adjustments consisting only of normal recurring accruals necessary for a fair presentation of the results have been recorded for the interim periods. Amounts shown in the consolidated financial statements and applicable notes are stated (except as otherwise indicated and as to share data) in millions, which amounts may not add to totals shown due to truncation. Necessary reclassifications are made in prior periods' financial statements whenever appropriate to conform to the most current presentation.

Earnings Per Share [Abstract]
Common Share Data	Common Share Data:
	Earnings Per Share - Consolidated basic earnings per share excludes the dilutive effect of common stock equivalents and is computed by dividing income available to common stockholders by the weighted-average number of common shares actually outstanding for the quarterly and year-to-date periods. Diluted earnings per share are similarly calculated with the inclusion of dilutive common stock equivalents. The following table provides a reconciliation of net income and the number of shares used in basic and diluted earnings per share calculations.

Investments [Abstract]
Investments	Investments:
	The Company may classify its invested assets in terms of those assets relative to which it either (1) has the positive intent and ability to hold until maturity, (2) has available for sale or (3) has the intention of trading. As of March 31, 2015 and December 31, 2014, substantially all the Company's invested assets were classified as "available for sale."
	Fixed maturity securities classified as "available for sale" and other preferred and common stocks (equity securities) are included at fair value with changes in such values, net of deferred income taxes, reflected directly in shareholders' equity. Fair values for fixed maturity securities and equity securities are based on quoted market prices or estimates using values obtained from independent pricing services as applicable.
	The Company reviews the status and fair value changes of each of its investments on at least a quarterly basis during the year, and estimates of other-than-temporary impairments ("OTTI") in the portfolio's value are evaluated and established at each quarterly balance sheet date. In reviewing investments for OTTI, the Company, in addition to a security's market price history, considers the totality of such factors as the issuer's operating results, financial condition and liquidity, its ability to access capital markets, credit rating trends, most current audit opinion, industry and securities markets conditions, and analyst expectations to reach its conclusions. Sudden fair value declines caused by such adverse developments as newly emerged or imminent bankruptcy filings, issuer default on significant obligations, or reports of financial accounting developments that bring into question the validity of previously reported earnings or financial condition, are recognized as realized losses as soon as credible publicly available information emerges to confirm such developments. Absent issuer-specific circumstances that would result in a contrary conclusion, any equity security with an unrealized investment loss amounting to a 20% or greater decline for a six month period is considered OTTI. In the event the Company's estimate of OTTI is insufficient at any point in time, future periods' net income (loss) would be adversely affected by the recognition of additional realized or impairment losses, but its financial position would not necessarily be affected adversely inasmuch as such losses, or a portion of them, could have been recognized previously as unrealized losses in shareholders' equity. The Company recognized no OTTI adjustments for the quarters ended March 31, 2015 and 2014.
	The amortized cost and estimated fair values by type and contractual maturity of fixed maturity securities are shown in the following tables. Expected maturities will differ from contractual maturities since borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

	At March 31, 2015, the Company held 141 fixed maturity and 14 equity securities in an unrealized loss position, representing 8.3% (as to fixed maturities) and 14.0% (as to equity securities) of the total number of such issues it held. At December 31, 2014, the Company held 322 fixed maturity and 11 equity securities in an unrealized loss position, representing 18.8% (as to fixed maturities) and 11.7% (as to equity securities) of the total number of such issues it held. Of the securities in an unrealized loss position, 57 and 117 fixed maturity securities had been in a continuous unrealized loss position for more than 12 months as of March 31, 2015 and December 31, 2014, respectively. The unrealized losses on these securities are primarily deemed to reflect changes in the interest rate environment. As part of its assessment of other-than-temporary impairments, the Company considers its intent to continue to hold, and the likelihood that it will not be required to sell investment securities in an unrealized loss position until cost recovery, principally on the basis of its asset and liability maturity matching procedures.
	Fair Value Measurements - Fair value is defined as the estimated price that is likely to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price) at the measurement date. A fair value hierarchy is established that prioritizes the sources ("inputs") used to measure fair value into three broad levels: inputs based on quoted market prices in active markets (Level 1); observable inputs based on corroboration with available market data (Level 2); and unobservable inputs based on uncorroborated market data or a reporting entity's own assumptions (Level 3). Following is a description of the valuation methodologies and general classification used for financial instruments measured at fair value.
	The Company uses quoted values and other data provided by a nationally recognized independent pricing source as inputs into its quarterly process for determining fair values of its fixed maturity and equity securities. To validate the techniques or models used by pricing sources, the Company's review process includes, but is not limited to: (i) initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; and (ii) comparing other sources including the fair value estimates to its knowledge of the current market and to independent fair value estimates provided by the investment custodian. The independent pricing source obtains market quotations and actual transaction prices for securities that have quoted prices in active markets and uses its own proprietary method for determining the fair value of securities that are not actively traded. In general, these methods involve the use of "matrix pricing" in which the independent pricing source uses observable market inputs including, but not limited to, investment yields, credit risks and spreads, benchmarking of like securities, broker-dealer quotes, reported trades and sector groupings to determine a reasonable fair value.
	Level 1 securities include U.S. and Canadian Treasury notes, publicly traded common stocks, the quoted net asset value ("NAV") mutual funds, and most short-term investments in highly liquid money market instruments. Level 2 securities generally include corporate bonds, municipal bonds, and certain U.S. and Canadian government agency securities. Securities classified within Level 3 include non-publicly traded bonds, short-term investments, and equity securities. There were no significant changes in the fair value of assets measured with the use of significant unobservable inputs as of March 31, 2015 and December 31, 2014.
	The following tables show a summary of assets measured at fair value segregated among the various input levels described above:

There were no transfers between Levels 1, 2 or 3 during the quarter ended March 31, 2015.
Investment income is reported net of allocated expenses and includes appropriate adjustments for amortization of premium and accretion of discount on fixed maturity securities acquired at other than par value. Dividends on equity securities are credited to income on the ex-dividend date. Realized investment gains and losses, which result from sales or write-downs of securities, are reflected as revenues in the income statement and are determined on the basis of amortized value at date of sale for fixed maturity securities, and cost in regard to equity securities; such bases apply to the specific securities sold. Unrealized investment gains and losses, net of any deferred income taxes, are recorded directly as a component of accumulated other comprehensive income in shareholders' equity. At March 31, 2015, the Company and its subsidiaries had no non-income producing fixed maturity securities.

Information About Segments of Business	Information About Segments of Business:
	Old Republic is engaged in the single business of insurance underwriting. The Company conducts its operations through a number of regulated insurance company subsidiaries organized into three major segments, namely its General Insurance Group (property and liability insurance), Title Insurance Group, and the Republic Financial Indemnity Group ("RFIG") Run-off Business. The results of a small life & accident insurance business are included with those of the holding company parent and minor corporate services operations. Each of the Company's segments underwrites and services only those insurance coverages which may be written by it pursuant to state insurance regulations and corporate charter provisions. Segment results exclude net realized investment gains or losses and other-than-temporary impairments as these are aggregated in the consolidated totals. The contributions of Old Republic's insurance industry segments to consolidated totals are shown in the following table.

	The material increases in mortgage guaranty insurance claims and loss payments that began in 2007 gradually depleted Republic Mortgage Insurance Company's ("RMIC") statutory capital base and forced it to discontinue writing new business. The insurance laws of 16 jurisdictions, including RMIC's and its affiliate company, Republic Mortgage Insurance Company of North Carolina's ("RMICNC") domiciliary state of North Carolina, require a mortgage insurer to maintain a minimum amount of statutory capital relative to risk in force (or a similar measure) in order to continue to write new business. The formulations currently allow for a maximum risk-to-capital ratio of 25 to 1, or alternatively stated, a "minimum policyholder position" ("MPP") of one-twenty-fifth of the total risk in force. The failure to maintain the prescribed minimum capital level in a particular state generally requires a mortgage insurer to immediately stop writing new business until it reestablishes the required level of capital or receives a waiver of the requirement from a state's insurance regulatory authority. RMIC breached the minimum capital requirement during the third quarter of 2010. RMIC had previously requested and, subsequently received waivers or forbearance of the minimum policyholder position requirements from the regulatory authorities in substantially all affected states. Following several brief extensions, the waiver from its domiciliary state of North Carolina expired on August 31, 2011, and RMIC and its affiliate company, RMICNC, discontinued writing new business in all states and limited themselves to servicing the run-off of their existing business. They were placed under the North Carolina Department of Insurance's ("NCDOI") administrative supervision the following year and ultimately ordered to defer the payment of 40% of all settled claims as a deferred payment obligation ("DPO").
	On July 1, 2014, the NCDOI issued a Final Order approving an Amended and Restated Corrective Plan (the "Amended Plan") submitted jointly on April 16, 2014, by RMIC and RMICNC. Under the Amended Plan, RMIC and RMICNC were authorized to pay 100% of their DPOs accrued as of June 30, 2014 and to settle all subsequent valid claims entirely in cash, without establishing any DPOs. In anticipation of receiving this Final Order, ORI invested $125.0 of cash and securities in RMIC during June 2014. In mid-July 2014, in furtherance of the Final Order, RMIC and RMICNC processed payments of their accumulated DPO balances of approximately $657.0 relating to fully settled claims charged to periods extending between January 19, 2012 and June 30, 2014. Both subsidiaries remain under the supervision of the NCDOI as they continue to operate in run-off mode. The approval of the Amended Plan notwithstanding, the NCDOI retains its regulatory supervisory powers to review and amend the terms of the Amended Plan in the future as circumstances may warrant.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities:
	Legal proceedings against the Company and its subsidiaries routinely arise in the normal course of business and usually pertain to claim matters related to insurance policies and contracts issued by its insurance subsidiaries. Other, non-routine legal proceedings which may prove to be material to the Company or a subsidiary are discussed below.
	A certified class action lawsuit is pending against the Company's principal title insurance subsidiary, Old Republic National Title Insurance Company ("ORNTIC"), in a federal district court in Pennsylvania (Markocki et al. v. ORNTIC, U.S. District Court, Eastern District, Pennsylvania, filed June 8, 2006). The plaintiffs allege that ORNTIC failed to give consumers reissue and/or refinance credits on the premiums charged for title insurance covering mortgage refinancing transactions, as required by filed rate schedules. The suit also alleges violations of the federal Real Estate Settlement Procedures Act ("RESPA"). ORNTIC is challenging the certification based on more recent case precedents.
	On December 19, 2008, Old Republic Insurance Company and Republic Insured Credit Services, Inc., ("Old Republic") filed suit against Countrywide Bank FSB, Countrywide Home Loans, Inc. ("Countrywide") and Bank of New York Mellon, BNY Mellon Trust of Delaware ("BNYM") in the Circuit Court, Cook County, Illinois (Old Republic Insurance Company, et al. v. Countrywide Bank FSB, et al.) seeking rescission of various credit indemnity policies issued to insure home equity loans and home equity lines of credit which Countrywide had securitized or held for its own account, a declaratory judgment and money damages based upon systemic material misrepresentations and fraud by Countrywide as to the credit characteristics of the loans or by the borrowers in their loan applications. Countrywide filed a counterclaim alleging a breach of contract, bad faith and seeking a declaratory judgment challenging the factual and procedural bases that Old Republic had relied upon to deny or rescind coverage for individual defaulted loans under those policies, as well as unspecified compensatory and punitive damages. The Court ruled that Countrywide does not have standing to counterclaim with respect to the policies insuring the securitized loans because those policies were issued to BNYM. In response, Countrywide and BNYM jointly filed a motion asking the Court to allow an amended counterclaim in which BNYM would raise substantially similar allegations as those raised by Countrywide and make substantially similar requests but with respect to the policies issued to BNYM. The Court dismissed their motion, with leave to re-plead the counterclaim. BNYM's subsequent attempt to re-plead was granted by the Court. No trial date has been set.
	On December 31, 2009, two of the Company's mortgage insurance subsidiaries, Republic Mortgage Insurance Company and Republic Mortgage Insurance Company of North Carolina (together "RMIC") filed a Complaint for Declaratory Judgment in the Supreme Court of the State of New York, County of New York, against Countrywide Financial Corporation, Countrywide Home Loans, Inc., The Bank of New York Mellon Trust Company, N.A., BAC Home Loans Servicing, LP, and Bank of America N.A. as successor in interest to Countrywide Bank, N.A. (together "Countrywide")(Republic Mortgage Insurance Company, et al v. Countrywide Financial Corporation, et al). The suit relates to five mortgage insurance master policies (the "Policies") issued by RMIC to Countrywide or to the Bank of New York Mellon Trust Company as co-trustee for trusts containing securitized mortgage loans that were originated or purchased by Countrywide. RMIC has rescinded its mortgage insurance coverage on over 1,500 of the loans originally covered under the Policies based upon material misrepresentations of the borrowers in their loan applications or the negligence of Countrywide in its loan underwriting practices or procedures. Each of the coverage rescissions occurred after a borrower had defaulted and RMIC reviewed the claim and loan file submitted by Countrywide. The suit seeks the Court's review and interpretation of the Policies' incontestability provisions and its validation of RMIC's investigation procedures with respect to the claims and underlying loan files.
	On January 29, 2010, in response to RMIC's suit, Countrywide served RMIC with a demand for arbitration under the arbitration clauses of the same Policies. The demand raises largely the same issues as those raised in RMIC's suit against Countrywide, but from Countrywide's perspective, as well as Countrywide's and RMIC's compliance with the terms, provisions and conditions of the Policies. The demand includes a prayer for punitive, compensatory and consequential damages. RMIC filed a motion to stay the arbitration, and Countrywide filed a motion to dismiss RMIC's lawsuit and to compel the arbitration. On July 26, 2010, the Court granted Countrywide's motion, ordering the matters be submitted to arbitration and dismissing the lawsuit. The arbitration is proceeding.
	On December 30, 2011 and on January 4, 2013, purported class action suits alleging RESPA violations were filed in the Federal District Court, for the Eastern District of Pennsylvania targeting RMIC, other mortgage guaranty insurance companies, PNC Financial Services Group (as successor to National City Bank) and HSBC Bank USA, N.A., and their wholly-owned captive insurance subsidiaries. (White, Hightower, et al. v. PNC Financial Services Group (as successor to National City Bank) et al.), (Ba, Chip, et al. v. HSBC Bank USA, N.A., et al.). The lawsuits are two of twelve against various lenders, their captive reinsurers and the mortgage insurers, filed by the same law firms, all of which were substantially identical in alleging that the mortgage guaranty insurers had reinsurance arrangements with the defendant banks' captive insurance subsidiaries under which payments were made in violation of the anti-kickback and fee splitting prohibitions of Sections 8(a) and 8(b) of RESPA. Ten of the twelve suits have been dismissed. The remaining suits seek unspecified damages, costs, fees and the return of the allegedly improper payments. A class has not been certified in either suit and RMIC has filed motions to dismiss the cases.
	On May 16, 2013, Bank of America, N.A. ("B of A") filed a demand for arbitration with the American Arbitration Association against both Republic Mortgage Insurance Company and Republic Mortgage Insurance Company of North Carolina (together, "RMIC") under the arbitration provisions of the RMIC Master Policy of mortgage guaranty insurance issued to B of A. The demand relates to RMIC's denials of certain claims and rescissions of coverage as to other claims. B of A alleges RMIC's actions were in breach of contract, in breach of RMIC's duty of good faith and fair dealing and in bad faith. The allegations are substantially similar to those raised by B of A's affiliates, Countrywide Financial Corporation and Countrywide Home Loans, Inc. in their arbitration demand against RMIC. B of A is a plaintiff in that proceeding as well, in its capacity as successor in interest to Countrywide Bank, N.A. B of A's demand requests a declaratory judgment with respect to the interpretation of certain policy provisions, B of A's compliance with certain terms and conditions of the policy, and the propriety of certain coverage positions and claims administration procedures of RMIC. The demand also seeks unspecified money damages, punitive, compensatory and consequential damages, interest, attorneys' fees and costs. The arbitration is proceeding.
	On August 26, 2014, Bank of America, N.A. ("B of A") filed suit against both Republic Mortgage Insurance Company and Republic Mortgage Insurance Company of North Carolina (together, "RMIC") in the General Court of Justice, Superior Court Division for Mecklenburg County, North Carolina. The complaint arises in connection with a RMIC bulk mortgage guaranty insurance policy issued to B of A and several RMIC traditional primary mortgage guaranty insurance policies issued to correspondent lenders from whom B of A acquired loans or servicing rights on loans for which certificates of insurance were issued under such policies. The complaint relates to RMIC's denials and curtailments of certain claims and rescissions and cancellations of coverage as to other claims. B of A alleges RMIC's actions were in breach of contract, in breach of RMIC's duty of good faith and fair dealing and in bad faith. The allegations are substantially similar to those asserted by B of A in the May 16, 2013 American Arbitration Association arbitration demand against RMIC, and relate to loans that were dismissed from that proceeding. B of A's demand requests a declaratory judgment with respect to the interpretation of certain policy provisions, B of A's compliance with certain terms and conditions of the policy, and the propriety of certain coverage positions and claims administration procedures of RMIC. The demand also seeks money damages, punitive, compensatory and consequential damages, interest, attorneys' fees and costs.
	On October 9, 2014, Intellectual Ventures I LLC and Intellectual Ventures II LLC (collectively, "IV") served a complaint naming as defendants Old Republic National Title Insurance Company, Old Republic Title Insurance Group, Inc., Old Republic Insurance Company and Old Republic General Insurance Group, Inc. (collectively, "Old Republic")(Intellectual Ventures I LLC et al. v. Old Republic General Insurance Group, Inc. et al.). The lawsuit is pending in the United States District Court for the Western District of Pennsylvania. IV alleges that Old Republic has infringed three patents and seeks damages, costs, expenses, and pre-judgment and post-judgment interest for the alleged infringement, in addition to injunctive relief. On October 14, 2014, Old Republic filed a motion to dismiss each count of the complaint on the grounds that the patents fail to meet the patentability test established by the United States Supreme Court in Alice Corp. Pty. Ltd. v. CLS Bank, 134 S.Ct. 2347 (2014).
	On January 20, 2015, Intellectual Ventures II LLC filed two complaints in the United States District Court for the Eastern District of Texas naming as defendants Great West Casualty Company and BITCO General Insurance Corporation and BITCO National Insurance Company. (Intellectual Ventures II LLC v. Great West Casualty Company) and (Intellectual Ventures II LLC v. BITCO General Insurance Corporation et al.) The plaintiff alleges a single patent infringement and seeks damages, costs, expenses, and pre-judgment and post-judgment interest in addition to injunctive relief. On April 9, 2015, plaintiff amended each complaint to allege a second patent infringement claim.
	Under GAAP, an estimated loss is accrued only if the loss is probable and reasonably estimable. The Company and its subsidiaries have defended and intend to continue defending vigorously against each of the aforementioned actions. The Company does not believe it probable that any of these actions will have a material adverse effect on its consolidated financial position, results of operations, or cash flows, though there can be no assurance in those regards. The Company has made an estimate of its potential liability under certain of these lawsuits, the counterclaim, and the arbitration, all of which seek unquantified damages, attorneys' fees, and expenses. Because of the uncertainty of the ultimate outcomes of the aforementioned disputes, additional costs may arise in future periods beyond the Company's current reserves. It is also unclear what effect, if any, the run-off operations of RMIC and its limited capital will have in the actions against it.

	Total debt	$	961.7		$	1,086.40		$	965		$	1,074.70
	On September 23, 2014, the Company completed a public offering of $400.0 aggregate principal amount of Senior Notes. The notes bear interest at a rate of 4.875% per year and mature on October 1, 2024.
	The Company completed a public offering of $550.0 aggregate principal amount of Convertible Senior Notes in early March, 2011. The notes bear interest at a rate of 3.75% per year, mature on March 15, 2018, and are convertible at any time prior to maturity by the holder into 64.3407 shares (subject to periodic adjustment under certain circumstances) of common stock per one thousand dollar note.
	The Company's 3.75% Convertible Senior Notes and 4.875% Senior Notes ("the Notes") contain provisions defining certain events of default, among them a court ordered proceeding due to the insolvency of a Significant Subsidiary. The Notes define Significant Subsidiary in accordance with the paragraph (w) of Rule 1-02 of the SEC's Regulation S-X. The Company's flagship mortgage guaranty insurance carrier, RMIC qualifies as a Significant Subsidiary for purposes of the Notes. If RMIC were to become statutorily impaired, its insolvency could trigger a receivership proceeding which, in turn could ultimately result in an event of default. If this were to occur, the outstanding principal of the Notes could become immediately due and payable. Management believes the Final Order by the North Carolina Department of Insurance to RMIC has precluded such an event of default from occurring in the foreseeable future. Moreover, RMIC was statutorily solvent at March 31, 2015 and is expected to be an increasingly less significant subsidiary with the payment of the DPO balances and as its run-off book extinguishes itself.
	Fair Value Measurements - The Company utilizes indicative market prices, which incorporate recent actual market transactions and current bid/ask quotations to estimate the fair value of outstanding debt securities that are classified within Level 2 of the fair value hierarchy as presented below. The Company uses an internally generated interest yield market matrix table, which incorporates maturity, coupon rate, credit quality, structure and current market conditions to estimate the fair value of its outstanding debt securities that are classified within Level 3.
	The following table shows a summary of the carrying value and fair value of financial liabilities segregated among the various input levels described in Note 3 above:

Income Taxes	Income Taxes:
	Tax positions taken or expected to be taken in a tax return by the Company are recognized in the financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. To the best of management's knowledge, there are no tax uncertainties that are expected to result in significant increases or decreases to unrecognized tax benefits within the next twelve month period. The Company views its income tax exposures as primarily consisting of timing differences whereby the ultimate deductibility of a taxable amount is highly certain but the timing of its deductibility is uncertain. Such differences relate principally to the timing of deductions for loss and premium reserves. As in prior examinations, the Internal Revenue Service ("IRS") could assert that claim reserve deductions were overstated thereby reducing the Company's statutory taxable income in any particular year. The Company believes that it establishes its reserves fairly and consistently at each balance sheet date, and that it would succeed in defending its tax position in these regards. Because of the impact of deferred tax accounting, the possible accelerated payment of tax to the IRS would not necessarily affect the annual effective tax rate. The Company classifies interest and penalties as income tax expense in the consolidated statement of income. The IRS is currently examining the Company's 2011 through 2013 consolidated Federal income tax returns, including amendments, relative to claims for recovery of income taxes previously paid.
