The earliest inhabitants of Gabon were pygmy hunter-gatherers; Baka pygmies continue to inhabit the northern forests, while the Babongo remain in parts of the southeast. Bantu-speaking farmers originating in present-day Cameroon migrated south and east across the African continent from around 500 BC, leaving evidence of pottery and tools at Njole in central Gabon. Later Bantu migrations from the north included the Mpongwe in the 15th century and the Fang in the 18th century.
