On June 19, 1865, the 250,000 enslaved people of Texas learned they were free, ending slavery in the United States. This day was soon to be memorialized with the dedication of a park in Houston. The park was called Emancipation Park, and the day it honored would come to be known as Juneteenth. In the voice and memory of the park itself — its fields and pools, its protests and cookouts, and, most of all, its people—the 150-year story of Emancipation Park is brought to life.
