The suppression of the transatlantic slave trade in West Africa by the American and British navies after 1808 also produced new settlers, as these two navies would settle liberated slaves in Liberia or Sierra Leone. In the later 19th century, Liberia had to economically compete with European colonies in Africa. The economy of Liberia was always based on the production of agricultural produce for export. In particular, Liberia's important coffee industry was destroyed in the 1870s by the emergence of production in Brazil.
