In 1866, he went on an unprecedented national tour promoting his executive policies, seeking to break Republican opposition.[1] As the conflict grew between the branches of government, Congress passed the Tenure of Office Act restricting Johnson's ability to fire Cabinet officials. He persisted in trying to dismiss Secretary of War Edwin Stanton, but ended up being impeached by the House of Representatives and narrowly avoided conviction in the Senate. He did not win the 1868 Democratic presidential nomination and left office the following year.
Johnson returned to Tennessee after his presidency and gained some vindication when he was elected to the Senate in 1875, making him the only president to afterwards serve in the Senate. He died five months into his term. Johnson's strong opposition to federally guaranteed rights for black Americans is widely criticized. Historians have consistently ranked him one of the worst presidents in American history.
