This is one of the largest political rallies for human rights in United States history and called for civil and economic rights for African Americans. It took place in Washington, D.C. on Wednesday, August 28, 1963. Martin Luther King, Jr. stood in front of the Lincoln Memorial, and delivered his historic "I Have a Dream" speech advocating racial harmony during the march. The march was organized by a group of civil rights, labor, and religious organizations, under the theme "jobs and freedom". Around two hundred-thousand to three hundred-thousand people were present during this march. About seventy-five to eighty percent of the marchers were black and the rest were white. This march was widely credited with helping the Civil Rights Act of 1964 and the Voting Rights Act of 1965 be passed.
