Susan D. Greenbaum, Afro-Cubans in Ybor City: A Centennial History (Tampa: [s.n.], 1986)

Black Cuban cigarmakers organized Los Libres Pensadores de Marti y Maceo (Freethinkers of Marti and Maceo) in Ybor City, a neighborhood of Tampa, Florida, on October 26, 1900, after a split with white Cubans from the Club Nacional Cubano. They took their name from Jose Martí, poet and hero of the war of independence, and Antonio Maceo, the anticolonialist black general called the "Bronze Titan." After its merger in 1904 with La Union, another Afro-Cuban organization from West Tampa, Marti-Maceo, now known as La Sociedad la Unión Martí-Maceo, became a mutual aid society that provided medical care and death benefits to its members. In 1909, the society built its substantial headquarters at 11th Street and 6th Avenue in Ybor City. Very active in the racial struggle, Marti-Maceo forged links in the 1940s with African Americans and Afro-Puerto Ricans in New York.
