アメリカ合衆国憲法修正第13条
The election of 1864 united War Democrats with the GOP and saw Lincoln and Tennessee Democratic Senator Andrew Johnson get nominated on the National Union Party ticket; Lincoln was re-elected. Under Republican congressional leadership, the Thirteenth Amendment to the United States Constitution—which banned chattel slavery in the United States—passed the Senate in 1864 and the House in 1865; it was ratified in December 1865.
