The Emancipation Proclamation became effective on Jan. 1, 1863. But for many slaves in the Confederate South, it had little immediate effect — they had to wait for the Union army to come and enforce it. One such case occurred in Galveston, Texas, on June 18, 1865. On the following day, the freed slaves held a large celebration, which became an annual tradition, and Juneteenth was born. Here in San Francisco, the 63rd Annual Juneteenth Celebration commemorates the 150th anniversary of the Emancipation Proclamation with a parade, car show, and full day of arts, crafts, and live music. The opening ceremony will feature appearances from Mayor Ed Lee and Supervisors Malia Cohen and London Breed, and grooves for the street festival come courtesy of Bobbie "Spider" Web and the Smooth Blues Band. The Juneteenth celebration is also being held in conjunction with the San Francisco Black Film Festival. (see page 18 for details).
