Question: James K. Polk ended a binary dispute with the British in 1846 with what treaty?

<P0-S0> James Knox Polk (November 2, 1795 – June 15, 1849) was the 11th President of the United States (1845–49). <P0-S1>  He previously served as the 13th Speaker of the House of Representatives and as Governor of Tennessee. <P0-S2>  A protege of Andrew Jackson, Polk was a member of the Democratic Party and an adherent of Jacksonian democracy and Manifest Destiny. <P0-S3>  During his presidency, the United States expanded significantly with the annexation of Republic of Texas, the Oregon Treaty, and the conclusion of the Mexican-American War. <SEP> <P1-S0> The Oregon Treaty is a treaty between the United Kingdom and the United States that was signed on June 15, 1846, in Washington, D.C. Signed under the presidency of James K. Polk, the treaty brought an end to the Oregon boundary dispute by settling competing American and British claims to the Oregon Country; the area had been jointly occupied by both Britain and the U.S. since the Treaty of 1818. <SEP> <P2-S0> The inauguration of James K. Polk as the 11th President of the United States took place on Tuesday, March 4, 1845, a rainy day with morning thunderstorms. <P2-S1>  The inauguration marked the commencement of the only four-year term of James K. Polk as President and George M. Dallas as Vice President. <P2-S2>  Polk was sworn in at the East Portico of the United States Capitol by Chief Justice Roger B. Taney. <P2-S3>  This was the first inaugural ceremony to be reported by telegraph and to be shown in a newspaper illustration (in "The Illustrated London News"). <SEP> <P3-S0> Polk Place was the home of 11th President of the United States James K. Polk and his wife Sarah Childress Polk on Vine Street in Nashville, Tennessee, which he purchased from his mentor Felix Grundy. <P3-S1>  It was called "Grundy Place" and was changed to "Polk Place." <P3-S2>  It was his final residence and where he died in 1849 at age 53. <P3-S3>  After his death his wife continued to reside there. <P3-S4>  During the Civil War, Polk Place was considered neutral ground by both the Confederate and Union armies. <P3-S5>  In spite of the fact that she had nephews fighting on the Confederate side, Union Generals Ulysses S. Grant and Don Carlos Buell frequently paid their respects to the former first lady. <P3-S6>  After a short illness, Mrs. Polk died at Polk Place in 1891, just short of her 88th birthday. <P3-S7>  James K. Polk's tomb was located on the front lawn until 1893, when it was moved to the Tennessee State Capitol. <P3-S8>  What followed was a long legal dispute centered on James K. Polk's will, after which the heirs of President and Mrs. Polk sold Polk Place. <P3-S9>  The state of Tennessee nearly acquired Polk Place and made it the governor's mansion (at the time, the governor of Tennessee stayed in a hotel room). <P3-S10>  A developer bought the house and had it demolished in 1900 to build a small apartment building. <P3-S11>  The YWCA bought the property in 1909 and built a new state-of-the-art facility. <P3-S12>  They sold the building in 1978 and moved to Woodmont Avenue. <P3-S13>  The Capitol Hotel (formerly Best Western) now occupies the former site of Polk Place.
