"We do not wish to evangelize, but to ignite, and when the moment arrives the flame will burst forth." — 1912, Karl Marx Circle, Naples

Founder of the Italian Communist Party and a leading left-communist theorist. He championed parliamentary abstentionism and an 'invariant revolutionary program,' debating Lenin directly at the Second Comintern Congress.

Non-Soviet revolutionary 1900–1980 ○ Natural causes

'Gallo': commander in Spain and the Resistance, PCI secretary-general who endured Cominform self-criticism and succeeded Togliatti

When he succeeded Togliatti as PCI secretary-general in 1964, Longo declared: 'I am a secretary, not a boss.'

A founder of the Italian Communist Party (PCI) at the 1921 Livorno Congress, Longo fought as inspector-general of the International Brigades in the Spanish Civil War under the nom de guerre 'Gallo.' During World War II he commanded the communist Garibaldi Brigades in the Italian Resistance and afterwards served as PCI deputy secretary under Palmiro Togliatti. In September 1947 he attended the founding Cominform conference at Szklarska Poręba as the PCI's delegate alongside Eugenio Reale, where the PCI and the French Communist Party were subjected to harsh criticism and forced into a self-critical turn toward militant struggle. Succeeding Togliatti as secretary-general in 1964, Longo pursued the 'Italian road to socialism' with growing autonomy from Moscow and formally opposed the Soviet invasion of Czechoslovakia in 1968.

Non-Soviet revolutionary 1905–1986 ○ Natural causes

Italian delegate at the Cominform founding who witnessed Stalin's telephone line, later turning from communist to anti-communist critic

"Stalin was its absolute master, without even condescending to put in an appearance. We were made conscious of this fact in the course of our debates by the existence of a direct telephone line between our Szklarska Poręba castle and the Kremlin." (1966 memoir)

An Italian communist politician and physician, he served as Undersecretary for Foreign Affairs in the postwar governments and as ambassador to Poland. As an Italian delegate to the 1947 Szklarska Poręba conference that founded the Cominform, his 1966 memoir became the most detailed eyewitness account of the proceedings, documenting Stalin's unseen control through a direct telephone line to the Kremlin and Zhdanov's pre-arranged attacks on the French and Italian parties for failing to seize power. He broke with the PCI in 1956 over the Soviet invasion of Hungary and spent his later decades as an anti-communist critic, founding the journal Corrispondenza Socialista.

Non-Soviet revolutionary 1922–1984 ○ Cerebral hemorrhage

Architect of Eurocommunism who led the West's largest non-ruling communist party

In a landmark interview with La Repubblica (28 July 1981), he named the structural corruption of Italy's party system the 'moral question' (questione morale): "Today's parties are above all machines of power and clientelism: scant or distorted knowledge of society and people's lives; ideas, ideals, programs few or vague; sentiments and civic passion — zero." The phrase became a reference point in Italian political discourse for decades.

Secretary-General of the Italian Communist Party (PCI, 1972–1984). Architect of Eurocommunism, a democratic, pluralist socialism independent of Moscow, who led the PCI to its historic peak of 34.4% in the 1976 general election.
