Muhammad Ali's contribution to civil rights and social justice was profound and multifaceted. Not only was he an iconic boxer, but he also became a prominent figure in the civil rights movement in the 1960s and 1970s. Ali refused military service during the Vietnam War on the grounds of his religious beliefs and opposition to the war, famously stating, "I ain’t got no quarrel with them Viet Cong." His stance drew attention to issues of racial injustice and helped to elevate the conversation around civil rights and anti-war sentiments. Ali's activism made him an enduring symbol of courage and resistance against oppression.
