Rustin was born in West Chester, Pennsylvania, to Florence Rustin and Archie Hopkins, but raised by his maternal grandparents, Julia (Davis) and Janifer Rustin, as the ninth of their twelve children; growing up he believed his biological mother was his older sister. His grandparents were relatively wealthy local caterers who raised Rustin in a large house. Julia Rustin was a Quaker, although she attended her husband's African Methodist Episcopal Church. She was also a member of the National Association for the Advancement of Colored People (NAACP). NAACP leaders such as W.E.B. Du Bois and James Weldon Johnson were frequent guests in the Rustin home. With these influences in his early life, in his youth Rustin campaigned against racially discriminatory Jim Crow laws.
