Mod originated in London, England in the late 1950s and peaked in the early-to-mid 1960s. The term mod came from   the 1959 novel Absolute Begginers by Colin Macinnes which describes as a modernist, a young modern jazz fan who dresses in sharp modern Italian clothes. Absolute Beginners may be one of the earliest use of the term modernist being used to describe young British style-conscious modern jazz fans. The mod subculture includes fashion,Pop Music, American Soul, Jamaican Ska, and British Beat and R&B. The Mods were British working class Youths with a stuck up image.
