The Oi! movement is a subculture that emerged in the late 1960s and early 1970s in the United Kingdom. It is closely associated with the working-class youth and is characterized by its distinctive music style, which blends elements of punk rock and reggae. The movement often addresses themes of social and political issues, reflecting the frustrations and experiences of the working class. The term "Oi!" itself is a form of greeting and is often used in the lyrics of songs by bands within this genre. Notable bands associated with the Oi! movement include Cockney Rejects, Sham 69, and The Business. The movement has also been linked to various social and political movements, including skinhead culture and football culture.
