Bulgaria

Non-Soviet revolutionary 1856–1924 ○ Natural causes

Founder of Bulgarian socialism who organized Russia's first Marxist circle

In August 1891, with political assemblies banned, Blagoev secretly gathered some twenty socialists on Buzludzha Peak in the Balkan Mountains and founded Bulgaria's first Social Democratic Party.

While a student at St. Petersburg University, he organized Russia's first Marxist circle (the 'Party of Russian Social Democrats') in 1883 and published the illegal newspaper Rabochii (Worker). Arrested and deported to Bulgaria, he founded the Bulgarian Social Democratic Party at the 1891 Buzludzha Congress, led the revolutionary 'Narrow' (Tesnyaki) wing after the 1903 split, edited the theoretical journal Novo Vreme for 25 years, and translated Marx's Capital into Bulgarian. He opposed the Balkan Wars and World War I, advocated a Balkan Federation, and after the October Revolution aligned with the Bolsheviks, transforming the party into the Bulgarian Communist Party in 1919 and becoming its first leader. An independent revolutionary who never fully accepted Lenin's worker-peasant alliance, he laid the theoretical foundations of Bulgarian Marxism.

Co-founder of the Bulgarian Communist Party and Comintern General Secretary (1922–24).

Elected Comintern General Secretary in 1935, he formalized the anti-fascist Popular Front strategy.

A leader of the Bulgarian Agrarian National Union (BZNS), he studied law in Paris after the First World War and returned in 1929 to work as a journalist. He co-founded the anti-fascist Fatherland Front in 1943 but broke from it in 1945 to lead the opposition against the Communists' monopolisation of power, and in the 1946 election his opposition coalition won 101 seats in the Grand National Assembly. Arrested in parliament in June 1947 and sentenced to death in August for a supposed military plot, he was hanged on 23 September, eight days after the Paris peace treaty came into force.
