Abraham Lincoln was born in a log cabin in Kentucky on February 12, 1809. When he was a small boy, his family moved to the frontier of Indiana. Here, his mother taught him to read and write.
    When his family moved to the state of Illinois Lincoln began to study law in his spare time. He soon became one of the best known lawyers in the state capital at Springfield, Illinois. It was here that Lincoln became famous for his debates with Stephen A. Douglas on the subject of slavery.
    In 1860, Lincoln was elected president of the United States. Soon after his election, some of the Southern states withdrew from the Union and set up the Confederate States of America. This brought on the terrible Civil War. During the war, on January 1,1863, Lincoln issued the famous Emancipation Proclamation. In 1865, after the war ended, the Thirteenth Amendment was added to the Constitution of the United States. This amendment put an end to slavery everywhere in the United States.
    On April 14,1865, a year after Lincoln was again elected to the presidency, he was shot in the head by John Wilkes Booth in Ford’s Theater in Washington, D.C. The President died the next day. In his death, the world lost one of the greatest men of all time.
