Really? You make it sound like it was exclusively founded by them.
Pre-History: The Niagara Movement
In 1905, a group of 32 prominent, outspoken African Americans met to discuss the challenges facing "people of color" (a term used to describe people who were not white) and possible strategies and solutions. Among the issues they were concerned about was the disfranchisement of blacks in the South starting in 1890 to 1908, when Southern legislatures ratified new constitutions creating barriers to voter registration and more complex election rules. Voter registration and turnout dropped markedly in the South as a result. Men who had been voting for 30 years were told they did not "qualify" to register.
Because hotels in the U.S. were segregated, the men convened under the leadership of Harvard scholar W. E. B. Du Bois at a hotel (Fort Erie Hotel) on the Canadian side of Niagara Falls in Fort Erie, Ontario. As a result, the group came to be known as the Niagara Movement. A year later, three whites joined the group: journalist William E. Walling, social worker Mary White Ovington, and social worker Henry Moskowitz, then Associate Leader of the New York Society for Ethical Culture.
The fledgling group struggled for a time with limited resources and internal conflict and disbanded in 1910.[9] Many members of the Niagara Movement then went on to join the NAACP. Although both organizations shared membership and overlapped in their existence, the Niagara Movement was a separate organization and is historically thought of as having a more radical platform than the NAACP. The Niagara Movement was formed exclusively by African Americans, while the meeting which birthed the idea of the NAACP was with three white people.
I know you'd like to take credit for any and all achievements made by African-Americans...but that would be wishful thinking on your part. Whenever you lie, I'd correct you.
