In early April 1963, the black people in Birmingham, under the leadership of Dr. Martin Luther King and the Southern Christian Leadership Congress, ignited the fire of the struggle for freedom. They took demonstrations such as marches, petitions, and sit-ins to demand the elimination of racial discrimination in shops, restaurants, schools, and employment.

In early May, the Birmingham incident in which police used batons, police dogs, etc. against unarmed demonstrators caused outrage among blacks across the country and the attention of domestic public opinion. Since then, civil rights protests have expanded rapidly.

More than 200,000 blacks and whites from all 50 states in the United States held the largest demonstration ever in Washington. At 11 a.m., the march departed from the Washington Monument, divided into two columns, and marched to the Lincoln Memorial. They put forward slogans such as "Freedom Now", "We Want to Work", "We March to Become First Class Citizens Now!".
