During the nineteenth century, northern Esanland was continually attacked and sacked by the Muslim Nupe people in the hunt for slaves and converts to Islam, having previously taken over the Kukuruku peoples’ lands. Many Esan kingdoms from the south helped in the battle to fend off the Nupes. The battles came into the Esans’ favor; several Nupe and Etsako warriors were brought into Esan cities where their posterity reside today. The nineteenth century brought increasing influence of Europe on Esanland, as the English demanded palm-products.
