Oscar Micheaux was born in 1884, in Metropolis, Illinois, one of 13 children of former slaves. When he was 17 years old he left home for Chicago, where he got a job as a Pullman porter, one of the best jobs an African-American could get in the days of Jim Crow laws that separated the races and were a legal bulwark of racism. Inspired by the self-help, assimilationist teachings of Booker T. Washington and the "Go West" pioneer philosophy of Horace Greeley, Micheaux acquired two 160-acre tracts of land in Gregory County, South Dakota, in 1905, despite no previous experience in farming.
Micheaux's experiences as a homesteader were the basis for his first novel, "The Conquest: The Story of a Negro Pioneer", which was published in 1913. He rewrote it into his most famous novel, "The Homesteader" (1917), which he self-published and distributed, selling it door-to-door to small businessmen and homesteaders in small towns, white people with whom he lived and did business with. "The Homesteader" not only elucidated Micheaux's understanding of societal cleavages but proselytized for assimilating black and white communities. Micheaux was firmly dedicated to the idea of art as a didactic medium.
Micheaux married Alice B. Russell in March 1926, and the two remained married until his death in March 1951. He was buried at Great Bend Cemetery, Great Bend, Kansas.
