What exactly is Juneteenth? It is a celebration marking the end of slavery in the United States. The first time this holiday was celebrated was June 19, 1865. After the Civil War ended Major General Gordon Granger, arrived in Galveston, Texas. He quickly spread the news that the war had ended and that the slaves had been freed. As you hopefully remember from reading Lincoln’s speeches during Jump #6, the Emancipation Proclamation freed the slaves on January 1, 1863. Sadly, it took two years from the time the Emancipation Proclamation became law until it could be enforced in Texas. Every year since then, Juneteenth has been celebrated on June 19th with parades, parties, and other celebrations.
