History of the Impeachment of Andrew Johnson, President of the United States, by the House of Representatives, and his trial by the Senate for high crimes and misdemeanors in office, 1868 Andrew Johnson (December 29, 1808 – July 31, 1875) was the 17th President of the United States, serving from 1865 to 1869. Johnson became president as Abraham Lincoln's Vice President at the time of Lincoln's assassination. A Democrat who ran with Lincoln on the National Union ticket, Johnson came to office as the Civil War concluded. The new president favored quick restoration of the seceded states to the Union. His plans did not give protection to the former slaves, and he came into conflict with the Republican-dominated Congress, culminating in his impeachment by the House of Representatives. The first American president to be impeached, he was acquitted in the Senate by one vote. Johnson was born in poverty in Raleigh, North Carolina. Apprenticed as a tailor, he worked in several frontier towns before settling in Greeneville, Tennessee. He served as alderman and mayor there before being elected to the Tennessee House of Representatives in 1835. After brief service in the Tennessee Senate, Johnson was elected to the federal House of Representatives in 1843, where he served five two-year terms. He became Governor of Tennessee for four years, and was elected by the legislature to the Senate in 1857. In his congressional service, he sought passage of the Homestead Bill, which was enacted soon after he left his Senate seat in 1862.
