Maybe she assumed I knew.
Formal slavery was legal until 1865 in most of the area that is now the United States. Many slaves were of African origin and many slave owners were of European descent, although some other groups also had slaves. By 1860, there were about four million slaves in the United States. On April 16, 1862, Abraham Lincoln, who was the US president at the time, signed the Compensated Emancipation Act, which freed more than 3000 slaves in the District of Columbia. However, slavery did not officially end in the rest of the United States until after the American Civil War, which lasted from 1861 until 1865.
The Thirteenth Amendment to the United States Constitution formally ended slavery in the US. It was proposed on January 31, 1865, and ratified by 30 of the then 36 states in the same year. However, it was only ratified in Mississippi in 1995. Slavery and the racial divisions, upon which it was based, have had and continue to have huge implications for individuals and American society as a whole.
Emancipation Day in Washington DC marks the anniversary of the signing of the Compensated Emancipation Act. On January 4, 2005, legislation was signed to make Emancipation Day an official public holiday in the District of Columbia.
EMANCIPATION DAYS ELSEWHERE
Elsewhere in the United States, the emancipation of slaves is celebrated in Florida (May 20), Puerto Rico (March 22) and Texas (June 19). There are also similar events in many countries in the Caribbean, including Anguilla, Bahamas, Bermuda, Barbados, Guyana, Jamaica, Trinidad and Tobago and the Turks and Caicos Islands. Many of these events occur during the first week of August as slavery was abolished in the British Empire on August 1, 1834.
