The Cultural Revolution (Arabic: ال زاهف, romanized: al-zahf) (also known as the People's Revolution or the Green Terror) in Libya was a nearly four-year period of political and social change in Libya. It started with Muammar Gaddafi's declaration of a cultural revolution during a speech in Zuwarah on 15 April 1973. This came after increasing tensions between Gaddafi and his colleagues in the Revolutionary Command Council (RCC) had led him to agree to step down. Gaddafi had told the RCC that he would announce his resignation to the people during his Zuwara speech, but he instead surprised them with his declaration of the Cultural Revolution. By the end of the Cultural Revolution period, Gaddafi was the uncontested leader of Libya.
The Cultural Revolution continued to at least September 1974, when the independence of action of the People's Committees was reduced by the national leadership in the Revolutionary Command Council. In a wider sense, it came to its conclusion in the establishment of Gaddafi's "state of the masses" ("jamahiriya") in 1977.
