How did the Communist Party of Cuba become the country’s only legal political party?

The Communist Party of Cuba (PCC) became the country’s sole legal political party through a process of revolutionary consolidation and constitutional reform following the 1959 revolution.12

In the early 1960s, the government dissolved existing political parties and merged three key revolutionary organizations—Fidel Castro’s 26th of July Movement, the Popular Socialist Party, and the Revolutionary Directorate—into a single entity. This group was reorganized several times before being officially designated as the Communist Party of Cuba in 1965.13

The party’s status as the only legal political entity was formally established under the 1976 constitution, which was approved by members at the party's first congress in 1975 and subsequently ratified in a national referendum. This single-party rule was further reinforced in the 1992 revised constitution, which defined the PCC as the "organized vanguard of the Cuban nation". Today, the party remains the leading force of the state and society, and no other political parties are permitted to compete for power.12
