Explanation:

Andrew Johnson was the 17th president of the United States. He became president after the assassination of Abraham Lincoln.

During the period of the U.S. Civil War (1861-1865), Johnson was a Southern senator and the only one who remained loyal to the Union among the southern senators. He tried restoring the south to the Union and clashed with radical Republicans. He had frequent clashes with congress and was impeached in 1868 although he was not removed from the office.
