After being narrowly defeated in the 1839 election, Everett was appointed Minister to Great Britain, serving until 1845. He next became President of Harvard, a job he quickly came to dislike. In 1849, he became an assistant to longtime friend and colleague Daniel Webster, who had been appointed Secretary of State. Upon Webster's death Everett served as Secretary of State for a few months until he was sworn in as U.S. Senator from Massachusetts. In the later years of his life, Everett traveled and gave speeches all over the country. He supported efforts to maintain the Union before the Civil War, running for Vice President on the Constitutional Union Party ticket in 1860. He was active in supporting the Union effort during the war and supported Lincoln in the 1864 election.
