The Niagara Movement was a civil-rights group founded in 1905 near Niagara Falls. Scholar and activist W. E. B. Du Bois gathered with supporters on the Canadian side of Niagara Falls to form an organization dedicated to social and political change for African Americans. Its list of demands included an end to segregation and discrimination in unions, the courts, and public accommodations, as well as equality of economic and educational opportunity.
