This Sunday is Juneteenth, the oldest known celebration commemorating the end of slavery. It’s observed across the country, but it marks the day in 1865 when slavery ended in Texas. That was more than two years after the Emancipation Proclamation. Contrary to popular belief, the proclamation did not eradicate slavery. It applied only to slave-holding rebel states. Slaves in Union states like Maryland remained captive. It wasn’t until 1864 that Maryland elected to free the state’s slaves through a referendum, by a margin of just 375 votes. How did it happen? And what was life in this divided state like for newly emancipated slaves? The end of slavery in Maryland.
