first piece of African-American utopian fiction on account of its vision of a peaceful and equal polity of men and women, whites and former slaves. In contrast, the 1899 novel Imperium in Imperio by Sutton Griggs (1872–1933) ends with preparations for a violent takeover of Texas for African Americans by a secret black government. Imperium in Imperio is credited with being the first political novel written by an African American. Griggs self-published his novel and sold it door-to-door. Early 20th century Of One Blood (1902) by the prolific writer and editor Pauline Hopkins (1859–1930), describing the discovery of a hidden civilization with advanced technology in Ethiopia, is the first "lost race" novel by an African-American author. However, unlike other entrants into this genre, Hopkins' "lost race" offers a homecoming to her black protagonists. Light Ahead for the Negro, a 1904 novel by Edward A. Johnson (1860–1944), is an early attempt at imagining a realistic post-racist American society, describing how by 2006 Negroes are encouraged to read books and given land by the government. W. E. B.

Nnanga Kôn, a 1932 novel by Jean-Louis Njemba Medou, covers the disastrous first contact of white colonialists with the Bulu people. It became so popular in Medou's native Cameroon that it has become the basis of local folklore. 1934 saw the publication of two Nigerian novels describing the deeds of rulers in a mythic version of the country's past, Gandoki by Muhammadu Bello Kagara (1890–1971) and Ruwan Bagaja by Abubakar Imam.
