@insideedition: Why is June 19th known as #Juneteenth? The answer is rooted in history. "Juneteenth is an African-American holiday that celebrates the emancipation of slaves in Texas in 1865," Scholar Lori Brooks told Inside Edition Digital. Dr. Brooks explained that when Union General Gordon Granger arrived in #Texas, it was June 18, "and the next day he announced the emancipation of African-American slaves." Dr. Brooks added that the holiday gained new interest in the 1960s, as part of the Poor People's Campaign.
