Juneteenth —June 19-- acknowledges the date in 1865 when Federal troops went to Galveston, Texas, to publicly inform enslaved people that they were free. This occurred two years after the Emancipation Proclamation Act of 1863. An estimated 250,000 people were still enslaved when troops arrived and forced Texas slaveowners to relinquish ownership of the people.
Philadelphia International Airport (PHL) will observe Juneteenth by lighting its ramp tower red, black and green, the colors of the African American flag, from June 18-21.
