The Portuguese first landed on Lagos Island in 1472. Trade developed slowly, however, until the Portuguese were granted a series of asientos de negros—monopolies to sell slaves in the Spanish Americas—a century later. The local obas (kings) enjoyed good relations with the Portuguese, who called the island Onim (and later Lagos) and established a flourishing slave trade. British attempts to suppress the slave trade culminated in 1851 in a naval attack on Lagos and the deposition of the oba. The slave trade continued, however, until Lagos came under British control in 1861. Lagos is Nigeria’s largest city and one of the largest in sub-Saharan Africa. Until 1975 it was the capital of Lagos state, and until December 1991 it was the federal capital of Nigeria. Ikeja replaced Lagos as the state capital, and Abuja replaced Lagos as the federal capital. Join us and enjoy this West African megalopolis.
