Shakur was born in the Harlem neighborhood of New York City but relocated to Los Angeles in 1988, and by the time he released his debut album 2Pacalypse Now in 1991, he became 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). Later that year, after suffering legal troubles and a robbery and shooting, Shakur became heavily involved in the growing East Coast–West Coast hip hop rivalry.
