The Juneteenth Organization of New Boston will host its annual Juneteenth event at T&P Trailhead Park on Friday, June 14, and Saturday, June 15. Juneteenth, formally known as “Freedom Day”, is the oldest known celebration commemorating the emancipation of slavery in Texas in 1865. On this day, Union soldiers arrived in Galveston to order freedom for the enslaved people of the state — two months after the Confederacy surrendered in the Civil War.
