of 1813, he was appointed by Governor Caleb Strong to fill the U.S. Senate seat vacated by the resignation of Senator James Lloyd. He served from May 5, 1813, to May 30, 1816, winning reelection to the seat in 1814. He opposed the ongoing War of 1812 in these years, with his earlier diplomatic experience providing valuable knowledge to Federalist interests. He expressed approval of the 1814 Hartford Convention in which the New England states aired grievances concerning Republican governance of the country and the conduct of the war. Gore assented to the Treaty of Ghent that ended the war, but was unhappy that the nation had not gained anything from the war. He resigned in June 1816, unhappy with the politics of Washington and suffering from poor health. Although he was no longer active in politics, he continued to express opinions on the subjects of the day, opposing the 1820 Missouri Compromise and bemoaning the "great moderation & mediocrity" of Federalist Governor John Brooks. He was a presidential elector in 1816. Later years and legacy Gore remained active in the administration of Harvard, and was active in a number of organizations, including the American Academy of Arts and Sciences and the Massachusetts Historical Society (whose president he was from 1806 to 1818). He was also elected a member of the American Antiquarian Society in 1814. Gore spent most of his later years at his country estate in Waltham, suffering from worsening rheumatoid arthritis that made walking increasingly difficult. His declining health and lack of social scene in Waltham led him in 1822 to return to Boston in the winters. He died on March 1, 1827, in Boston, and is buried in its Granary Burying Ground. Gore's wife died in 1834; the couple had no children. The major beneficiary of the Gore estate was Harvard (which received an estimated $100,000), although bequests were also made to the American Academy of Arts and Sciences and the Massachusetts Historical Society. The Waltham estate passed through several hands and was subdivided over time. The mansion was saved from demolition by the Gore Place Society (established for the purpose of preserving it), which now operates it as a museum. It was declared a National Historic Landmark in 1970.
