Summary of Significant Accounting Policies	9 Months Ended

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 2019 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. Recent pronouncements are discussed below. a) Effective January 1, 2019, the Company adopted FASB guidance on lease accounting which requires balance sheet recognition of all leases with a term greater than 12 months. The Company's adoption of this guidance is discussed in Note 7. b) Effective January 1, 2020, the Company adopted the FASB’s current expected credit loss standard ("CECL") which requires the immediate recognition of estimated credit losses expected to occur over the remaining life of certain financial assets measured at amortized cost, including the Company’s reinsurance recoverables, held to maturity securities and its accounts and notes receivable. CECL replaces the current incurred loss impairment model that recognizes losses when a probability threshold is met with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased and at subsequent measurement dates. The expected credit losses, and subsequent adjustment to such losses, are recorded through an allowance account that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the asset presented on the consolidated balance sheet. The guidance also modifies the impairment model for available for sale fixed maturity securities by requiring the recognition of other than temporary impairments ("OTTI") relating to credit losses through an allowance account, as opposed to a charge that cannot be revised should the underlying security recover. Under the guidance, the length of time a security has been in an unrealized loss position will no longer impact the determination as to whether an OTTI loss exists. The guidance relating to financial assets measured at amortized cost was adopted on a modified retrospective basis, resulting in a net of tax adjustment to January 1, 2020 retained earnings of $2.3. The Company’s total credit loss allowance relating to financial assets increased from $30.1 as of January 1, 2020 to $35.7 at September 30, 2020. The September 30, 2020 allowance was comprised of $16.0 related to reinsurance recoverables and $19.7 related to accounts and notes receivable. At adoption, the allowance included $14.5 related to reinsurance recoverables, $15.5 related to accounts and notes receivable, and an immaterial amount related to held to maturity securities. The Company performs an ongoing evaluation of reinsurance balances outstanding and uses a probability-of-default methodology to estimate the credit allowance for uncollectible amounts. Allowances for uncollectible accounts and notes receivable are established based on a review of amounts outstanding, historical charge off activity, and current and forecasted economic conditions. The revised impairment guidance for available for sale fixed maturity securities was adopted on a prospective basis. Related disclosures relative to this standard’s impact on the Company’s investment portfolio are included in Note 3.

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 (loss) 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 (loss) and the number of shares used in basic and diluted earnings per share calculations.

Investments [Abstract]
Investment	Investments: The Company classifies its fixed maturity securities as those 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 June 30, 2020 the Company changed its intent to hold its tax exempt municipal bond portfolio until maturity and consequently, reclassified these securities from their previous held to maturity designation to available for sale. As a result, cumulative net of tax unrealized gains of $48.5 were recognized in other comprehensive income as of that date. The Company's entire fixed maturity portfolio is now classified as available for sale. Fixed maturity securities classified as "available for sale" are reported at fair value with changes in such values, net of deferred income taxes, reflected directly in shareholders' equity. Fixed maturity securities classified as "held to maturity" are carried at amortized cost. Equity securities are reported at fair value with changes in such values reflected as unrealized investment gains (losses) in the consolidated statements of income. Fair values for fixed maturity securities and equity securities are based on quoted market prices or estimates using values obtained from recognized independent pricing services. The status and fair value changes of each of the fixed maturity investments are reviewed at least once per quarter 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 audited financial statements, 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 the issuer's previously reported earnings or financial condition, are recognized as realized losses as soon as credible publicly available information emerges to confirm such developments. In the event the Company's estimate of OTTI is insufficient at any point in time, future periods' net income (loss) would be negatively impacted by the recognition of additional 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 directly in shareholders' equity. The Company recognized no OTTI adjustments for the quarter and nine months ended September 30, 2020, and $0 and $2.0 of OTTI adjustments for the quarter and nine months ended September 30, 2019, respectively. A summary of fixed maturity securities by type, contractual maturity and credit quality 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.

(b) "All other" includes non-investment grade or non-rated issuers. As described in Note 1, the Company adopted the FASB's accounting guidance on CECL effective January 1, 2020. The credit allowance for the Company's held to maturity fixed maturity securities was evaluated using a probability-of-default methodology and due to the high credit quality of the portfolio, the resulting allowance established was not material. As previously noted, the Company no longer classifies these fixed maturity securities as held to maturity. The following tables reflect the Company's gross unrealized losses and fair value, aggregated by category and length of time that individual available for sale and held to maturity fixed maturity securities have been in an unrealized loss position. Fair value and issuer's cost comparisons follow: Less than 12 Months 12 Months or Greater Total Fair Unrealized Losses Fair Unrealized Losses Fair Unrealized Losses September 30, 2020: Fixed Maturity Securities: Available for sale: U.S. & Canadian Governments $ 210.3 $ .1 $ — $ — $ 210.3 $ .1 Corporate 514.3 11.9 1.3 — 515.7 11.9 $ 724.7 $ 12.1 $ 1.3 $ — $ 726.0 $ 12.1 Number of available for sale securities in unrealized loss position 94 4 98 December 31, 2019: Fixed Maturity Securities: Available for sale: U.S. & Canadian Governments $ 217.2 $ .3 $ 53.0 $ .1 $ 270.3 $ .4 Corporate 176.4 1.9 54.3 .8 230.7 2.8 $ 393.7 $ 2.3 $ 107.4 $ 1.0 $ 501.1 $ 3.3 Number of available for sale securities in unrealized loss position 54 47 101 Held to maturity: Tax-exempt $ — $ — $ 21.7 $ — $ 21.7 $ — Number of held to maturity securities in unrealized loss position — 8 8 In the above tables the unrealized losses on fixed income securities reflect changes in the interest rate environment and the effects of the COVID-19 pandemic and the associated governmental responses. As part of its assessment of other-than-temporary impairments, the Company considers its intent to continue to hold the securities, and the likelihood that it will not be required to sell investment securities in an unrealized loss position until cost recovery, principally in consideration of its asset and liability matching objectives. The following table shows cost and fair value information for equity securities: Equity Securities Gross Gross Estimated September 30, 2020 $ 3,271.0 $ 776.3 $ 364.4 $ 3,682.9 December 31, 2019 $ 3,089.1 $ 968.0 $ 26.6 $ 4,030.5 During the third quarter and first nine months of 2020 and 2019, the Company recognized pretax unrealized investment gains (losses) of $79.2 and $(529.4), respectively for 2020, and $57.3 and $439.3, respectively for 2019, emanating from changes in the fair value of equity securities in the consolidated statements of income. Changes in the fair value of equity securities still held at September 30, 2020 and 2019 were $78.9 and $(520.6) for the third quarter and first nine months of 2020, respectively, and $78.0 and $438.5 for the third quarter and first nine months of 2019, respectively. 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: Level 1 inputs are based on quoted market prices in active markets; Level 2 observable inputs are based on corroboration with available market data; and Level 3 unobservable inputs are based on uncorroborated market data or a reporting entity's own assumptions. 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 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) comparisons with other sources including the fair value estimates based on current market quotations, and with independent fair value estimates provided by the independent investment custodian. The independent pricing source obtains market quotations and actual transaction prices for securities that have quoted prices in active markets and uses their 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, mutual funds, and 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 and equity securities. There were no significant changes in the fair value of Level 3 assets as of September 30, 2020 and December 31, 2019. The following tables show a summary of the fair value of financial assets segregated among the various input levels described above: Fair Value Measurements As of September 30, 2020: Level 1 Level 2 Level 3 Total Available for sale: Fixed maturity securities: U.S. & Canadian Governments $ 1,157.8 $ 807.7 $ — $ 1,965.5 Tax-exempt — 1,071.0 — 1,071.0 Corporate — 7,159.6 10.5 7,170.1 Short-term investments 748.1 — — 748.1 Equity securities $ 3,681.0 $ — $ 1.8 $ 3,682.9 As of December 31, 2019: Available for sale: Fixed maturity securities: U.S. & Canadian Governments $ 1,068.1 $ 810.7 $ — $ 1,878.8 Corporate — 6,907.1 10.5 6,917.6 Short-term investments 484.3 — — 484.3 Held to maturity: Fixed maturity securities: Tax-exempt — 1,058.2 — 1,058.2 Equity securities $ 4,028.7 $ — $ 1.7 $ 4,030.5 There were no transfers between Levels 1, 2 or 3 during the nine months ended September 30, 2020. 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. At September 30, 2020, the Company and its subsidiaries had no non-income producing fixed maturity or equity securities. Realized investment gains and losses, which result from sales or impairments 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. The following table reflects the composition of net investment income, net realized gains or losses, and the net change in unrealized investment gains or losses for each of the periods shown.

Insurance [Abstract]
Losses, Claims and Settlement Expenses	Losses, Claims and Settlement Expenses:The establishment of claim reserves by the Company's insurance subsidiaries is a reasonably complex and dynamic process influenced by a large variety of factors. These factors principally include past experience applicable to the anticipated costs of various types of claims, continually evolving and changing legal theories emanating from the judicial system, recurring accounting, statistical, and actuarial studies, the professional experience and expertise of the Company's claim departments' personnel or attorneys and independent claim adjusters, ongoing changes in claim frequency or severity patterns such as those caused by natural disasters, illnesses, accidents, work-related injuries, and changes in general and industry-specific economic conditions. Consequently, the reserves established are a reflection of the opinions of a large number of persons, of the application and interpretation of historical precedent and trends, of expectations as to future developments, and of management's judgment in interpreting all such factors. At any point in time, the Company is exposed to the incurrence of possibly higher or lower than anticipated claim costs due to all of these factors, and to the evolution, interpretation, and expansion of tort law, as well as the effects of unexpected jury verdicts. All reserves are therefore based on estimates which are periodically reviewed and evaluated in the light of emerging claim experience and changing circumstances. The resulting changes in estimates are recorded in operations of the periods during which they are made. Return and additional premiums and policyholders' dividends, all of which tend to be affected by development of claims in future years, may offset, in whole or in part, favorable or unfavorable claim developments for certain coverages such as workers' compensation, portions of which are written under loss sensitive programs that provide for such adjustments. The Company believes that its overall reserving practices have been consistently applied over many years, and that its aggregate net reserves have generally resulted in reasonable approximations of the ultimate net costs of claims incurred. However, no representation is made nor is any guaranty given that ultimate net claim and related costs will not develop in future years to be greater or lower than currently established reserve estimates. The Company’s accounting policy regarding the establishment of claim reserve estimates is described in Note 1(h) to the consolidated financial statements included in Old Republic’s 2019 Annual Report on Form 10-K. The following table shows an analysis of changes in aggregate reserves for the Company's losses, claims and settlement expenses for each of the periods shown. This space left intentionally blank Summary of changes in aggregate reserves for claims and related costs: Nine Months Ended September 30, 2020 2019 Gross reserves at beginning of period $ 9,929.5 $ 9,471.2 Less: reinsurance losses recoverable 3,249.7 3,006.3 Net reserves at beginning of period: General Insurance 6,021.3 5,766.1 Title Insurance 530.9 533.4 RFIG Run-off 118.9 154.5 Other 8.4 10.8 Sub-total 6,679.7 6,464.9 Incurred claims and claim adjustment expenses: Provisions for insured events of the current year: General Insurance 1,787.9 1,815.9 Title Insurance 80.8 71.3 RFIG Run-off (a) 36.2 29.9 Other 8.3 10.9 Sub-total 1,913.4 1,928.1 Change in provision for insured events of prior years: General Insurance (11.6) (11.1) Title Insurance (19.6) (18.0) RFIG Run-off (a) (7.8) (6.4) Other (2.3) (3.2) Sub-total (41.4) (38.7) Total incurred claims and claim adjustment expenses (a) 1,871.9 1,889.3 Payments: Claims and claim adjustment expenses attributable to insured events of the current year: General Insurance 505.9 562.2 Title Insurance 1.9 2.2 RFIG Run-off .6 2.0 Other 4.8 7.2 Sub-total 513.4 573.8 Claims and claim adjustment expenses attributable to insured events of prior years: General Insurance 968.3 1,068.4 Title Insurance 35.5 49.8 RFIG Run-off 23.9 51.3 Other 1.9 2.9 Sub-total 1,029.8 1,172.5 Total payments 1,543.2 1,746.3 Amount of reserves for unpaid claims and claim adjustment expenses at the end of each period, net of reinsurance losses recoverable: General Insurance 6,323.4 5,940.1 Title Insurance 554.5 534.6 RFIG Run-off 122.7 124.6 Other 7.7 8.3 Sub-total 7,008.4 6,607.8 Reinsurance losses recoverable 3,548.6 3,209.5 Gross reserves at end of period $ 10,557.1 $ 9,817.4 __________ (a) In common with all other insurance coverages, RFIG Run-off mortgage guaranty settled and incurred claim and claim adjustment expenses include only those costs actually or expected to be paid by the Company. Changes in mortgage guaranty aggregate case, IBNR, and loss adjustment expense reserves entering into the determination of incurred claim costs, take into account, among a large number of variables, claim cost reductions for anticipated coverage rescissions and claims denials. Estimates of coverage rescissions and claim denials are no longer material to Old Republic's consolidated financial statements.

Retirement Benefits [Abstract]
Pension Plans	Employee Benefit Plans: The Company had an active pension plan (the "Plan") covering a portion of its work force until December 31, 2013. The Plan is a defined benefit plan pursuant to which pension payments are based primarily on years of service and employee compensation near retirement. The Plan was closed to new participants and benefits were frozen as of December 31, 2013. As a result, eligible employees retained all of the vested rights as of the effective date of the freeze. While additional benefits no longer accrue, the Company's cumulative obligation continues to be subject to further adjustment due to changes in actuarial assumptions such as expected mortality and changes in interest rates. Net periodic pension costs for the quarterly periods ended September 30, 2020 and 2019 were not material to Old Republic's consolidated statements of income. During the first quarter of 2020, the Employee Savings and Stock Ownership Plan (ESSOP) purchased 3.3 million shares of Old Republic common stock for $50.0. The purchases were financed by loans to the ESSOP from participating subsidiaries.

Segment Reporting [Abstract]
Information About Segments of Business	Information About Segments of Business: Old Republic is engaged in the single business of insurance underwriting and related services. The Company conducts its operations through a number of regulated insurance company subsidiaries organized into three major segments, namely its General Insurance (property and liability insurance), Title Insurance, and the Republic Financial Indemnity Group ("RFIG") Run-off Business. The results of a small life and accident insurance business are included with those of the parent holding company and its internal corporate services subsidiaries. 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 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities: (a) Legal Proceedings - 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. At September 30, 2020, the Company had no material non-claim litigation exposures in its consolidated business. (b) Leases - Several of the Company’s subsidiaries maintain their offices in leased premises. A number of these leases provide for the payment of real estate taxes, insurance, and other operating expenses. In addition, many of the subsidiaries also lease equipment for use in their businesses. Substantially all of the Company’s leases are classified as operating leases. Effective January 1, 2019, the Company adopted new lease accounting guidance issued by the FASB which requires the balance sheet recognition of all leases with a term greater than 12 months. The Company’s adoption of this standard resulted in the establishment of a right of use asset ($226.9) and corresponding lease liability ($241.4) equal to the present value of future lease payments, reflected within sundry assets and liabilities in the consolidated balance sheet. Furthermore, the Company recognized $18.4, net of tax, in previously deferred gains associated with sale leaseback transactions as an adjustment to beginning retained earnings.

Income Tax Disclosure [Abstract]
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 Company is not currently under audit by the IRS and 2017 and subsequent tax years remain open.
