The Esan Kingdoms often warred among each other. Despite the wars, the Esans kept a homogenous culture that was chiefly influenced by the Benin Empire. However, these kingdoms were colonized, along with the Benin Empire, by the British Empire during September 1897, only gaining independence 63 years later in 1960 when Nigeria became independent from British Colonial rule. After independence, the Esan people have suffered from civil war, poverty, and lack of infrastructure.
