Carlos Baliño in the context of Popular Socialist Party (Cuba)

The Popular Socialist Party (Spanish: Partido Socialista Popular, PSP) was a communist party in Cuba. It was founded in 1925 as the Cuban Communist Party (Partido Comunista Cubano) by José Miguel Pérez, Carlos Baliño, Alfonso Bernal del Riesgo, and Julio Antonio Mella. The party later merged with the Revolutionary Union (Unión Revolucionaria) to form the Communist Revolutionary Union (Unión Revolucionaria Comunista) on 13 August 1939. The party was renamed Popular Socialist Party on 22 January 1944, but with the Auténticos' victory in the 1944 elections, the party went into decline.

The party published the daily newspaper Hoy ("Today") until 1950.
