Question: Widespread segregation in 19th- and early 20th-century North America made it difficult for African-Americans to join Lodges outside of Prince Hall jurisdictions and impossible for inter-jurisdiction recognition between the parallel U.S. Masonic authorities. By the 1980s, such discrimination was a thing of the past, and today most U.S. Grand Lodges recognise their Prince Hall counterparts, and the authorities of both traditions are working towards full recognition.

While celebrating their heritage as lodges of black Americans, Prince Hall is open to all men regardless of race or religion.
