Document 6: Richmond, Virginia: In 1990 religion and politics intersected to impact the outcome of the Eighth District election in South Richmond.

As the first African American Baptist Minister elected to the Richmond City Council, Prince's election paved the way for a political paradigm shift in politics that persist today. Following Prince's election, Reverend Gwendolyn Hedgepeth and the Reverend Leonidas Young, former Richmond Mayor were elected to public office. Prior to Prince's election black clergy made political endorsements and served as appointees to the Richmond School Board and other boards throughout the city.
