Today is Juneteenth, a day that celebrates the abolition of slavery in Texas in 1865. Even though the Emancipation Proclamation had been signed in 1863, it wasn't until Union soldiers marched into Galveston and announced the end of the Civil War that slavery was officially terminated. Since then, as yesterday's Time piece nicely explains, the portmanteau of a holiday has become a "de facto second Independence Day...and a first step toward inclusion in the greater American Dream."
