What was the main reason African American parents sued a Kansas school board in 1954? To advocate the desegregation of public schools to promote nonviolent resistance as a means of achieving civil rights to encourage the segregation of schools to demand that their children's education be equal to white students' education

African American parents sued a Kansas school board in 1954 to demand that their children's education be equal to white students' education.

Explanation:

The question refers to the case of Brown v. Board of Education of Topeka, which was resolved in 1954 by the Supreme Court in a ruling that disallowed school segregation in the United States.

The case was started in 1951, after Linda Brown, an African American student, was rejected at a white-only school in her neighborhood. This rejection, based on the "separate but equal" principle, forced her to go to a school a mile farther from her home. For this situation, the Browns sued the city board of education, demanding the inclusion of their daughter in said institution.

Finally, the Court forced the school to accept Linda, dismissing the segregationist doctrine.
