The congregation that became Dexter Avenue Baptist Church organized in 1877, twelve years after emancipation, among Black Montgomery residents who had until then worshipped separately within white controlled churches. The building it has occupied since 1889 sits on Dexter Avenue within sight of the Alabama State Capitol, a proximity that would matter far more than its builders could have anticipated.
Martin Luther King Jr. arrived as the church's new pastor in 1954, twenty five years old, and had held the pulpit barely a year when Rosa Parks was arrested in December 1955 for refusing to give up her bus seat to a white passenger. Montgomery's Black clergy organized a response within days, forming the Montgomery Improvement Association to coordinate a boycott of the city's bus system, and elected King, still new to the city, as its president.
The church's basement, rather than its sanctuary, is where much of that organizing work happened: strategy sessions, an alternative transportation network, and the planning that sustained a boycott lasting three hundred and eighty one days against organized resistance and violence, including the bombing of King's own nearby home. The boycott ended in December 1956 after a Supreme Court ruling declared Montgomery's bus segregation unconstitutional, establishing the tactic of sustained nonviolent economic pressure and King's national profile while still in his twenties.
King left Dexter Avenue in 1960 to co-pastor his father's church in Atlanta, but the Montgomery congregation kept its connection to that history deliberately alive, renamed Dexter Avenue King Memorial Baptist Church in 1978, its basement now holding a mural and museum recounting the boycott's planning.
