As head of the Comintern Information-Propaganda Department he coordinated the ideological line of foreign communist parties, and as director of the Institute of Red Professorship (Party History) he authored the 1935 Short History of the CPSU, the direct precursor to the 1938 Short Course.

When Nikolaos Zachariadis was transferred to Dachau, Siantos served as the party's acting general secretary and led the KKE, National Liberation Front (EAM), and Greek People's Liberation Army (ELAS) through the German occupation. He directed EAM forces during the December 1944 fighting, opposed disarmament, yet ultimately pursued negotiation. In February 1945 he led the EAM delegation that signed the Varkiza Agreement, whose disarmament terms became, amid the subsequent White Terror and renewed civil conflict, the political defeat of the EAM.

“Comrade Maslow, who is playing at Leftism and wishes to exercise himself 'hunting Centrists,' has more zeal than sense.” — Lenin, singling him out by name in his 'Letter to the German Communists' (14 August 1921).

Born into a Ukrainian Jewish merchant family, he abandoned a concert-pianist career to study physics under Einstein and Planck, then the First World War radicalized him into the KPD's founding. As Ruth Fischer's lifelong partner he took the party chairmanship in 1924 and drove 'Bolshevisation', a break with the united front and a one-sided crusade against Social Democracy, until Stalin and Thälmann displaced and expelled him in 1926, leaving him a lifelong anti-Stalinist dissident.

A diplomat from Olomouc, he served as envoy to the Netherlands, Romania, the United States, Switzerland and Austria and, as the exile government’s ambassador in Moscow during the war, grew close to the Soviet Union. Prime minister of the Košice government from April 1945, he led the National Front government until June 1946.

With his wife Devleta he rescued dozens of Jewish refugees, and as a vice president of AVNOJ elected in 1942 he embodied the partisan movement's multi-ethnic character.
