Nationalist ideas in Sub-Saharan Africa emerged during the mid-19th century among the emerging black middle classes in West Africa. Early nationalists hoped to overcome ethnic fragmentation by creating nation-states. In its earliest period, it was inspired by African-American and Afro-Caribbean intellectuals from the Back-to-Africa movement who imported nationalist ideals current in Europe and the Americas at the time. The early African nationalists were elitist and believed in the supremacy of Western culture but sought a greater role for themselves in political decision-making. They rejected African traditional religions and tribalism as "primitive" and embraced western ideas of Christianity, modernity, and the nation state. However, one of the challenges faced by nationalists in unifying their nation after European rule were the divisions of tribes and the formation of ethnicism.
