At the Second Congress of the SEKE in April 1920, the party decided to affiliate with Comintern. The Comintern was an international communist organisation founded in Moscow in 1919. The SEKE changed its name to the Socialist Labour Party of Greece-Communist (SEKE-K). A new central committee was elected, which included Nikos and Panaghis Dimitratos, Yannis Kordatos, G. Doumas and M. Sideris. At the Third Extraordinary Congress of the SEKE-K in November 1924, the party was renamed the Communist Party of Greece and adopted Marxism–Leninism. Pandelis Pouliopoulos was elected as general-secretary. Ever since, the party has functioned on the basis of democratic centralism.
