Fredrick Allen Hampton Sr. was an American activist. He came to prominence in Chicago as deputy chairman of the national Black Panther Party and chair of the Illinois chapter. As a progressive African American, he founded the anti-racist, anti-classist Rainbow Coalition, a prominent multicultural political organization that initially included the Black Panthers, Young Patriots, and the Young Lords, and an alliance among major Chicago street gangs to help them end infighting and work for social change. A Marxist–Leninist, Hampton considered fascism the greatest threat, saying, "nothing is more important than stopping fascism, because fascism will stop us all.”
