emerged in the mid-1970s. Preceded by a variety of protopunk music of the 1960s and early 1970s, punk rock developed between 1974 and 1977 in the United States, the United Kingdom, and Australia, where groups such as the Ramones, Sex Pistols, and The Clash were recognized as the vanguard of a new musical movement.
Punk rock bands, eschewing the perceived excesses of mainstream 1970s rock, created fast, hard music, typically with short songs, stripped-down instrumentation and often political or nihilistic lyrics. The associated punk subculture expresses youthful rebellion and is characterized by distinctive clothing styles, a variety of anti-authoritarian ideologies, and a DIY (do it yourself) attitude.
Punk rock became a major phenomenon in the United Kingdom during the late 1970s; its popularity elsewhere was more limited. During the 1980s, forms of punk rock emerged in small scenes around the world, often rejecting commercial success and association with mainstream culture. By the turn of the century, punk rock's legacy had led to the development of the alternative rock movement, and new punk rock bands popularized the genre decades after its first heyday.
