Muhammad Ali: Political activist, global humanitarian

Inside the ring, Muhammad Ali was a heavyweight champion, a showman, one of the greatest in the boxing world. But outside the ring? It's where Ali's greatness truly shone. While his activism against the Vietnam War and his comments on race relations in the 1960s led to much controversy, his devotion in his later years to humanitarian causes worldwide garnered much respect. Ali's death Friday at the age of 74 came after a lengthy battle with Parkinson's, a disease for which he spent decades raising money and awareness and appealing Congress for research funding. POLITICO takes a look back at Ali's moments in the political spotlight, his activism and his many efforts over the years to promote peace in the world.
