After Rosa Parks refused to give up her seat in the Montgomery bus boycott, it led to a citywide boycott against the racial segregation on busses. The March on Washington brought over 200,000 people to the Lincoln memorial fighting for jobs and the freedom of African Americans. Martin Luther King also delivered his "I have a Dream" speech there. The Chicago Freedom Movement was formed to protest segregated housing, educational deficiencies, and employment and health disparities based on racism. This led to the passage of the federal Fair Housing Act in 1968.
