Социалистическая народная партия
The Popular Socialist Party (, PSP) was a communist party in Cuba. Originally called the Communist Party of Cuba (), it was formed in 1925 by a group including Blas Roca, Anibal Escalante, Fabio Grobart, Alfonso Bernal del Riesgo and Julio Antonio Mella, who acted as its leader until his assassination in Mexico in 1929. It was later renamed the "Communist Revolutionary Union". After the electoral victory of the Partido Auténtico in the 1944 elections, the party went into decline, and eventually adopted the name "Popular Socialist Party" for electoral reasons.
