The Bridge Wars was a hip hop rivalry during the mid-to-late 1980s and early 1990s, that arose from a dispute over the true birthplace of hip hop music and retaliation over the rejecting of a record for airplay. The Bridge Wars originally involved The South Bronx's Boogie Down Productions, led by KRS-One, and Marley Marl's Juice Crew, hailing from Queensbridge. KRS-One and Marley Marl have since officially retired the feud, with the release of their collaborative 2007 album, Hip-Hop Lives.
