Calabar was once a major source of slaves brought down from the interior to be shipped west in the Atlantic slave trade. Slaving was suppressed by 1860, but the port of Calabar remained important for export of palm oil and other products. With improved roads into the interior, Calabar has regained importance as a port and is growing rapidly. The tropical rain forest in the Calabar River basin is second to none, and fish and shrimp catches in the estuary are common practice.
