Black men from across the country will assemble on Washington, D.C.'s National Mall on Oct. 10 to mark the 20th anniversary of the iconic Million Man March.

It served as a catalyst for scores of community organizations, such as the local 100 Black Men chapters of Greater Washington, D.C., and Savannah, Ga., which trace their origins to the Million Man March.

The National Association of Black Social Workers told USA Today that thousands of families inquired about adoption after the Million Man March.

But two decades ago, the Million Man March proved that black men could gather peacefully and responsibly, in huge numbers, to discuss the problems in their communities.

Two years after black men gathered in D.C., black women rallied in Philadelphia for the Million Woman March.
