When was segregated waiting rooms established?

Segregated waiting rooms, particularly in the context of the United States, were established during the late 19th and early 20th centuries, following the implementation of Jim Crow laws after the Reconstruction era. These laws enforced racial segregation in public facilities, including transportation hubs. The practice became widespread in the early 1900s and continued until the Civil Rights Movement of the 1960s, which sought to dismantle such discriminatory practices.
