Answer:
In the United States, the terms "freedmen" and "freedwomen" refer chiefly to former slaves emancipated during and after the American Civil War by the Emancipation Proclamation and the 13th Amendment.
The Freedmen's Bureau, formally known as the Bureau of Refugees, Freedmen and Abandoned Lands, was established in 1865 by Congress to help millions of former black slaves and poor whites in the South in the aftermath of the Civil War.
