Abraham Lincoln (; February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States (1861–1865). Lincoln led the nation through its greatest moral, constitutional, and political crisis in the American Civil War. On April 14, 1865, just days after the war's end at Appomattox, he was enjoying a night at the theatre with his wife Mary when he was assassinated by Confederate sympathizer and spy John Wilkes Booth. They had three children: Sarah, Abraham, and Thomas – who died in infancy.Thomas Lincoln bought or leased farms in Kentucky before losing all but 200 acres (81 ha) of his land in court disputes over property titles. In 1816, the family moved to Indiana where the land surveys and titles were more reliable.
