This stance aligned with that of the Spanish Socialist Workers' Party (Partido Socialista Obrero Español; PSOE), with which it was associated.
Following the Russian Revolution in 1917, there was an influx of new and more left-leaning members to the JSE, which caused it to diverge from the PSOE.
[2] On April 15, 1920, at the Fifth Congress of the JSE, the membership voted to break off from the PSOE, and founded the Spanish Communist Party,[3] leaving behind a small group that wished to rebuild the Socialist Youth of Spain, which continues to exist.
[1] Andrade continued as the founding editor of El Comunista, and in the first issue he published the statutes and thesis to be discussed at the new party's First Congress.
[1] The PSOE went through a similar schism at the following year's Congress, when the more left-leaning members (the terceristas) split off to form the Spanish Communist Workers' Party on April 13, 1921, after the PSOE had voted to join the International Working Union of Socialist Parties and reject the Communist International.
