Each population had a distinct ethnic, social, cultural and linguistic history. Members of these communities provided most of the labor that built and expanded the cocoa farming industry on Fernando Pó during the 1880s and 1890s. The Fernandinos of Fernando Po were closely related to each other. Because of the history of labor in this area, where workers were recruited, effectively impressed, from Freetown, Cape Coast, and Lagos, the Fernandinos also had family ties to those areas. Eventually these ethnically distinct groups intermarried and integrated. In 21st-century Bioko, their differences are considered marginal.
