Organized on February 18, 1894, Mount Zion Baptist Church is home to the largest African American congregation in Washington State. Under Reverend Samuel Berry McKinney’s leadership in the 1960s, the church was a major force in the local civil rights movement. On July 1, 1963, Reverend McKinney led 400 marchers from Mount Zion to City Hall in a push for an open housing ordinance in Seattle.
