The Communist Party of Cuba (Spanish: Partido Comunista de Cuba, PCC) is the sole ruling party of Cuba. It was founded on 3 October 1965 as the successor to the United Party of the Cuban Socialist Revolution, which was in turn made up of the 26th of July Movement and Popular Socialist Party that seized power in Cuba after the 1959 Cuban Revolution. The party governs Cuba as an authoritarian one-party state where dissidence and political opposition are prohibited and repressed. The Cuban constitution ascribes the role of the party to be the "leading force of society and of the state."
The highest body within the PCC is the Party Congress, which convenes every five years. When the Congress is not in session, the Central Committee is the highest body. Because the Central Committee meets twice a year, most day-to-day duties and responsibilities are vested in the Politburo. Since April 2021, the First Secretary of the Central Committee has been Miguel DÃaz-Canel, who has been serving as President of Cuba since 2018.
