April 16, 1862, President Lincoln signed the District of Columbia Compensated Emancipation Act. This law prohibited slavery in the District, forcing its 900-odd slaveholders to free their slaves, with the federal government paying owners an average of about $300 (equivalent to $9,000 in 2024) for each
Although there have been few reparations to the nations involved, one controversial development dates back to the 1800s. In 1833, the British government agreed to pay £20m to slave owners in exchange for the freeing of their slaves — which would equate to billions in the modern day
France went further by penalizing Haiti for the revolution that abolished slavery in its former colony St. Domingue. It levied a huge sum on the island, which crippled it in decades of debt. Former slaves were forced to pay indemnities to former slaveowners in exchange for official recognition as the first black independent nation-state in the Western Hemisphere.
Slaves were so valuable their owners were compensated by the Government.
