The term "rockabilly" is a portmanteau of "rock," from rock and roll, and "hillbilly", the latter a reference to the country music (often called "hillbilly music" in the 1940s and '50s) that contributed strongly to the style's development. Other important influences on rockabilly include Western Swing, blues music, boogie woogie, and Jump blues. Although there are notable exceptions, its origins lie primarily in the American South.
The influence and popularity of the style waned in the 1960s, but during the late 1970s and early 1980s, rockabilly enjoyed a major revival of popularity that has endured to the present, often within a rockabilly enthusiast subculture.
