In June, Truman became the first president to address the NAACP. His speech was a significant departure from traditional race relations in the United States. In front of 10,000 people at the Lincoln Memorial, the president left no doubt where he stood on civil rights. According to his speech, America had "reached a turning point in the long history of our country's efforts to guarantee freedom and equality to all our citizens…Each man must be guaranteed equality of opportunity."

"We must make the Federal government a friendly, vigilant defender of the rights and equalities of all Americans. And again I mean all Americans.":40
