Happy Juneteenth! This holiday marks the end of the official institution of slavery in the United States, and was historically widely celebrated by black Americans. The photo above is of a 1905 celebration in Richmond, Virginia.
On this day in 1865, enslaved people in Texas were informed of their freedom, two years following the Emancipation Proclamation. Also on this day, the Civil Rights Act of 1963 was passed, after an 83 day filibuster in the US Senate.
