For the non-Americans here (most members):
It is a Monday Holiday in the US. Juneteenth. It celebrates the real "official" end of slavery in the US.
That date fell in mid June in 1865. Any history buffs will know that the Emancipation Proclamation was issued in January of 1863, but that was not the end of slavery. After the civil war, which was fought over slavery (despite what some people now say), the last enslaved people were officially freed in June of 1865... in Texas.
Many slave owners in the South sent their enslaved people to Texas during the civil war, for "safe keeping" until they figured the Confederacy would win the war, and they could bring them back to the new Confederate States of America. It didn't work out that way.
It was in June of 1865 when the US Army arrived in Texas and "officially" ended slavery in the USA. I use quotes around "officially" because there were loopholes that took a while to overcome.
If you are curious about world history, I suggest you look into this chapter of US history. Here is a starting point...
