“Juneteenth is the official commemoration of the end of slavery in America. On June 19, 1865, enslaved people in Galveston, Texas were notified by a Union general that the Confederacy lost the Civil War and all of the enslaved were finally free. By the time the news reached Galveston, it had been about two months since the war ended and over two and a half years since the Emancipation Proclamation.”

“Juneteenth is short for ‘June 19th’ and is observed every year on that day.”
