Andrew Johnson (1808-75) was the 17th President of the United States, serving between 1865 and 1869. He was Vice President to Abraham Lincoln and became President when Lincoln was assassinated.
The most difficult task facing Johnson was the struggle to being the states together afer the Civil War. He was keen to do this as quickly as possible, but this meant he did not fight to protect the rights
of former slaves. Johnson was impeached - that is formally accused - for breaking the rules of the Presidency. Though he was acquitted by one vote he is one of only two Presidents to be impeached.
