The Black Panther Party, under the leadership of Newton, gained international support. This was most demonstrated when Newton was invited to visit China in 1970. He was welcomed enthusiastically by large crowds holding up copies of Quotations from Chairman Mao Tse-tung as well as signs supporting the BPP and criticizing U.S. imperialism.

After returning to the United States, Newton was tried for a variety of violent offenses such as assault and multiple murders. These charges resulted in him fleeing to Havana, Cuba to escape prosecution for three years. Upon his return, he stood trials for one more assault and murder and was acquitted of both charges. Compounding these challenges was the split that developed between Newton and Eldridge Cleaver in early 1971 over the primary function of the Party. Newton wanted the party to focus on serving African American communities while Cleaver thought the focus should be on building relationships with international revolutionary movements. This rift resulted in violence between the factions and the deaths of several BPP members.

In 1989, Newton was fatally shot in West Oakland by a member of the Black Guerilla Family and drug dealer named Tyrone Robinson. Relations between the Black Panther Party and the Black Guerilla Family had been strained for nearly twenty years prior to this incident. The murder occurred after Newton left a drug den in a neighborhood where Newton had once organized social programs. Newton’s last words were, “You can kill my body, and you can take my life but you can never kill my soul. My soul will live forever!” Robinson then shot Newton twice in the face. Newton is buried at Evergreen Cemetery in Oakland. Robinson was convicted of murder in 1991 and was sentenced to 32 years to life in prison.
