In the late 18th century and 19th century, African Americans comprised a substantial portion of Georgetown's population. The 1800 census reported the population in Georgetown at 5,120, which included 1,449 slaves and 227 free blacks.  A testament to the African-American history that remains today is the Mount Zion United Methodist Church, which is the oldest African-American congregation in Washington. Prior to establishing the church, free blacks and slaves went to the Dumbarton Methodist Church where they were restricted to a hot, overcrowded balcony. The church was originally located in a small brick meetinghouse on 27th Street, but it was destroyed in the 1880s due to fire. The church was rebuilt on the present site.  Mount Zion Cemetery offered free burials for Washington's earlier African-American population.  "From a pre-Civil War population of 6,798 whites, 1,358 free Negroes, and 577 slaves, Georgetown's population had grown to 17,300 but half these residents were poverty-stricken Negroes."
