Today is Juneteenth, and if you don’t know what that means in America, or for Black Americans, then comedians Dulcé Sloan and Amber Ruffin are here to help you, with these explainers they delivered last night on The Daily Show with Trevor Noah and Late Night with Seth Meyers, respectively.

For starters, the Emancipation Proclamation by President Abraham Lincoln in 1863 didn’t actually free all of the enslaved Black Americans. Just those people enslaved in certain parts of the Confederacy during the Civil War. Only two months after the Confederacy surrendered (even if they didn’t give up their heritage flags, and some still won’t stop fighting), on June 19, 1865, did word of freedom reach Texas.

Roll the clips!

Oh, and also Astronomy Club took Jimmy Fallon to school…
