Tupac Amaru Shakur ( TOO-pahk shə-KOOR; born Lesane Parish Crooks, June 16, 1971 – September 13, 1996), better known by his stage name 2Pac and by his alias Makaveli, was an American rapper, songwriter, and actor. He is considered by many to be one of the most influential rappers of all time. Much of Shakur's work has been noted for addressing contemporary social issues that plagued inner cities, and he is considered a symbol of resistance and activism against inequality. Shakur was born in Manhattan, a borough of New York City, but relocated to the San Francisco Bay Area in 1988. He moved to Los Angeles in 1993 to further pursue his music career. By the time he released his debut album 2Pacalypse Now in 1991, he had become a central figure in West Coast hip hop, introducing social issues in the genre at a time when gangsta rap was dominant in the mainstream. Shakur achieved further critical and commercial success with his follow-up albums Strictly 4 My N.I.G.G.A.Z... (1993) and Me Against the World (1995).Shakur became heavily involved in the growing East Coast–West Coast hip hop rivalry between 1995 and 1996. His double-disc album All Eyez on Me (1996) became certified Diamond by the RIAA. On September 7, 1996, Shakur was shot four times by an unknown assailant in a drive-by shooting in Las Vegas; he died six days later and the gunman was never captured. The Notorious B.I.G., Shakur's friend turned rival, was at first considered a suspect, but was also murdered in another drive-by shooting six months later. Five more albums have been released since his death, all of which have been certified platinum in the United States. Shakur is one of the best-selling music artists of all time having sold over 75 million records worldwide. In 2002, he was inducted into the Hip-Hop Hall of Fame. In 2017, he was inducted into the Rock and Roll Hall of Fame in his first year of eligibility. Rolling Stone named Shakur in its list of the 100 Greatest Artists of All Time. Outside music, Shakur also gained considerable success as an actor, with his starring roles as Bishop in Juice (1992), Lucky in Poetic Justice (1993) where he starred alongside Janet Jackson, Ezekiel in Gridlock'd (1997), and Jake in Gang Related (1997), all garnering praise from critics.

He is also known as 2Pac, Makaveli, Tupac Amaru Shakur, Tupac, Lesane Parish Crooks, Lesane Crooks and Tupac Omar Shakur.

During 1995, imprisoned, impoverished, and his mother about to lose her house, Tupac had his wife Keisha Morris get word to Marion "Suge" Knight, in Los Angeles, boss of Death Row Records. Reportedly, Tupac's mother promptly received $15,000. After an August visit to Clinton Correctional Facility in northern New York state, Suge traveled southward to New York City to join Death Row's entourage to the 2nd Annual Source Awards ceremony. Already reputed for strongarm tactics on the Los Angeles rap scene, Suge used his brief stage time mainly to belittle Sean "Puff Daddy" Combs, boss of Bad Boy Entertainment, the label then leading New York rap scene, who routinely performed with his own artists. Before closing with a brief comment of support for Tupac, Suge invited artists seeking the spotlight for themselves to join Death Row. Eventually, Puff recalled that to preempt severe retaliation from his Bad Boy orbit, he had promptly confronted Suge, whose reply — that he had meant Jermaine Dupri, of So So Def Recordings, in Atlanta — was politic enough to deescalate the conflict.

Still, among the fans, the previously diffuse rivalry between America's two mainstream rap scenes had instantly flared already. And while in New York, Suge visited Uptown Records, where Puff, under its founder Andre Harrell, had started in the music business through an internship. Apparently without paying Uptown, Suge obtained the releases of Puff's prime Uptown recruits Jodeci, its producer DeVante Swing, and Mary J. Blige, all then signing with Suge's management company. On September 24, 1995, at a party for Dupri in Atlanta at the Platinum House nightclub, a Bad Boy circle entered a heated dispute with Suge and Suge's friend Jai Hassan-Jamal "Big Jake" Robles, a Bloods gang member and Death Row bodyguard. According to eyewitnesses, including a Fulton County sheriff, working there as a nightclub bouncer, Puff had heatedly disputed with Suge inside the club, whereas several minutes later, outside the club, it was Puff's childhood friend and own bodyguard, Anthony "Wolf" Jones, who had aimed a gun at Big Jake, fatally shot while entering Suge's car.

The attorneys of Puff and his bodyguard both denied any involvement by their clients, while Puff's added that Puff had not even been with his bodyguard that night. Over 20 years later, the case remains officially unresolved. Yet immediately and persistently, Suge blamed Puff, cementing the enmity between the two bosses, whose two record labels dominated the rap genre's two mainstream centers. In the late 1990s, Southern rap's growth into the mainstream would dispel the East–West paradigm. But in the meantime, in October 1995, violating his probation, Suge visited Tupac in prison again. Suge posted $1.4 million bond. And with appeal of his December 1994 conviction pending, Shakur returned to Los Angeles and joined Death Row. On June 4, 1996, it released the 2Pac B side "Hit 'Em Up." In this venonmous tirade, the proclaimed "Bad Boy killer" threatens violent payback on all things Bad Boy—Biggie, Puffy, Junior M.A.F.I.A., the company—and on any in New York's rap scene, like rap duo Mobb Deep and obscure rapper Chino XL, who allegedly had commented against Shakur about the dispute.
