The Knights of Peter Claver organization was founded in 1909 in Mobile, Alabama. It is the largest African American Catholic lay organization in the United States. The organization was founded by the Josephites, a Catholic order whose mission was to serve Catholic African Americans. Josephite leaders were concerned that the Church would lose its African American members to other organizations, such as the Elks and the Masons, who had black lodges, if they did not have their own fraternal Catholic organization.
By 1910, the Knights of Peter Claver had branches in Norfolk and Richmond, Virginia; Nashville, Tennessee; and several towns in Mississippi. They later spread to the North as well and became a national presence by 1946.
The Knights were not initially active in the fight to desegregate the Catholic Church. One man, Marcellus Dorsey, was expelled from the order when he wrote articles criticizing racial segregation in the Church. By 1939 the Knights began to oppose segregation. They created a committee to support black priests and refused to send black priests to Africa, instead wishing to keep them in the United States to support the domestic black Catholic community. During the civil rights movement, the Knights also worked with the National Association for the Advancement of Colored People (NAACP) and the National Urban League.
The Knights of Peter Claver are named for Saint Peter Claver, a Jesuit priest. St. Peter Claver was born in Spain in 1581 and served the poor in Colombia and the West Indies. The objectives of the organization stem from the work of St. Peter Claver. These include promoting civic and social justice, contributing to charity, awarding scholarships, and nurturing relationships with the community, youth, and family. The Knights carry out their mission through several divisions, including the Ladies Auxiliary, the Junior Division, Junior Daughters, the Fourth Degree Knights, and the Fourth Degree Ladies of Grace. The Knights also publish a semi-annual newsletter called The Claverite.
