On June 19, 1865, a Union edict announced that all slaves in Texas were free.

Now, June 19th is known as Juneteenth (or Jubilee Day or Freedom Day). It's an official celebration of the end of slavery. This year, Juneteenth is falling in the midst of a massive revolutionary Black Lives Matter movement, which erupted following the recent death of George Floyd but which is an extension of the Civil Rights movement and a reaction to 400 years of Black oppression in America.
