The first celebration of Juneteenth began at the same courthouse in Galveston, on the same date where, one year before, enslaved people in Texas learned that the war was over and they were now free. On these same steps, Union Major General Gordon Granger had read, “The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free. This involves an absolute equality of personal rights and rights of property between former masters and slaves. …” On this day, June 19, 1866, the Emancipation Proclamation was read out loud, and then those gathered progressed to Methodist Episcopal South (now Reedy Chapel AME Church) for a public prayer meeting.
