The ECL was founded in 1923 when the Philadelphia-area Hilldale Club and the Bacharach Giants of Atlantic City, both associate members of the midwest-based Negro National League (NNL), broke with the NNL and allied with the white promoter Nat Strong to form an east coast league. The charter members were: Hilldale, the Bacharach Giants, the Brooklyn Royal Giants, the Cuban Stars (East), the Lincoln Giants of New York, and the Baltimore Black Sox.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
