The Rev. Martin Luther King, fresh off the success of the Montgomery bus boycotts, spoke to an overflow crowd at the First Baptist Church of North Tulsa 60 years ago today, on July 28, 1960.

The 31-year-old minister had recently positioned himself as the voice and face of the rising civil rights movement and was on a cross-country mission to mobilize black communities, encouraging them to vote in the upcoming presidential election in November 1960.

The Rev. Anthony Scott, First Baptist’s leader today, said the audience was estimated to be 1,500 to hear Rev. King.
