Why did federal government intervene in civil rights movement?

The federal government intervened in the Civil Rights Movement primarily to address systemic racial discrimination and uphold constitutional rights that were being denied to African Americans, particularly in the South. Key events, such as the violent responses to peaceful protests and the assassination of civil rights leaders, prompted federal action to protect citizens and enforce laws. Legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965 emerged to dismantle segregation and ensure voting rights, reflecting a commitment to promoting equality and justice.
