The connection between music and politics has been seen in many cultures. People in the past and present – especially politicians, politically-engaged musicians and listeners – hold that music can 'express' political ideas and ideologies, such as rejection of the establishment ('anti-establishment') or protest against state or private actions, including war through anti-war songs, but also energize national sentiments and nationalist ideologies through national anthems and patriotic songs. Because people attribute these meanings and effects to the music they consider political, music plays an important role in political campaigns, protest marches as well as state ceremonies. Much of the music that is considered political or related to politics are songs, and many of these are topical songs, i.e. songs with topical lyrics, made for a particular time and place.

Rock is a broad genre of popular music that originated as "rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles from the mid-1960s, particularly in the United States and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a 44 time signature using a verse–chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. Rock was the most popular genre of music in the U.S. and much of the Western world from the 1950s to the 2010s.
