Answer:n the years following the Civil War, the Bureau of Refugees, Freedmen, and Abandoned Lands (the Freedmen's Bureau) provided assistance to tens of thousands of former slaves and impoverished whites in the Southern States and the District of Columbia. The war had liberated nearly four million slaves and destroyed the region's cities, towns, and plantation-based economy. It left former slaves and many whites dislocated from there homes, facing starvation, and owning only the clothes they wore. The challenge of establishing a new social order, founded on freedom and racial equality, was enormous.
The Bureau was established in the War Department in 1865 to undertake the relief effort and the unprecedented social reconstruction that would bring freedpeople to full citizenship. It issued food and clothing, operated hospitals and temporary camps, helped locate family members, promoted education, helped freedmen legalize marriages, provided employment, supervised labor contracts, provided legal representation, investigated racial confrontations, settled freedmen on abandoned or confiscated lands, and worked with African American soldiers and sailors and their heirs to secure back pay, bounty payments, and pensions.
The records left by the Freedmen's Bureau through its work between 1865 and 1872 constitute the richest and most extensive documentary source available for investigating the African American experience in the post-Civil War and Reconstruction eras. Historians have used these materials to explore government and military policies, local conditions, and interactions between freedpeople, local white populations, and Bureau officials.
