Revolutionary socialism in the context of "World revolution"

Ba'athism, also spelled Baathism, is an Arab nationalist ideology which advocates the establishment of a unified Arab state through the rule of a Ba'athist vanguard party operating under a revolutionary socialist framework. The ideology is officially based on the theories of the Syrian intellectuals Michel Aflaq (per the Iraqi-led Ba'ath Party), Zaki al-Arsuzi (per the Syrian-led Ba'ath Party), and Salah al-Din al-Bitar. Ba'athist leaders of the modern era include the former president of Iraq Saddam Hussein, and former presidents of Syria Hafez al-Assad and his son Bashar al-Assad.

The Ba'athist ideology advocates the "enlightenment of the Arabs" as well as the renaissance of their culture, values and society. It also advocates the creation of one-party states and rejects political pluralism in an unspecified length of time—the Ba'ath party theoretically uses an unspecified amount of time to develop an "enlightened" Arab society. Ba'athism is founded on the principles of Arab nationalism, pan-Arabism, and Arab socialism, as exemplified by its slogan "Unity, Freedom, Socialism".

Anarchism in Russia developed out of the populist and nihilist movements' dissatisfaction with the government reforms of the time.

The first Russian to identify himself as an anarchist was the revolutionary socialist Mikhail Bakunin, who became a founding figure of the modern anarchist movement within the International Workingmen's Association (IWA). In the context of the split within the IWA between the Marxists and the anarchists, the Russian Land and Liberty organization also split between a Marxist faction that supported political struggle and an anarchist faction that supported "propaganda of the deed", the latter of which went on to orchestrate the assassination of Alexander II.

Bolshevism (derived from Bolshevik) is a revolutionary socialist current of Soviet Leninist and later Marxist–Leninist political thought and political regime associated with the formation of a rigidly centralized, cohesive and disciplined party of social revolution, focused on overthrowing the existing capitalist state system, seizing power and establishing the "dictatorship of the proletariat".

Bolshevism originated at the beginning of the 20th century in Russia and was associated with the activities of the Bolshevik faction within the Russian Social Democratic Labour Party led by Vladimir Lenin, Bolshevism's main theorist. Other theoreticians included Joseph Stalin, Leon Trotsky, Nikolai Bukharin and Yevgeni Preobrazhensky. While Bolshevism was based on Marxist philosophy, it also absorbed elements of the ideology and practice of the socialist revolutionaries of the second half of the 19th century (Sergey Nechaev, Pyotr Tkachev, Nikolay Chernyshevsky) and was influenced by Russian agrarian socialist movements like the Narodniks.

Neo-Ba'athism is a far-left variant of Ba'athism that became the state ideology of Ba'athist Syria, after the Arab Socialist Ba'ath party's Sixth National Congress in October 1963. As a result of the 1966 Syrian coup d'état launched by the neo-Ba'athist military committee led by Salah Jadid and Hafez al-Assad, Ba'ath party's Syrian regional branch was transformed into a militarist organization that became completely independent of the National Command of the original Ba'ath Party.

Neo-Ba'athism has been described as a divergence from Ba'athism proper that had gone beyond its pan-Arabist ideological basis by stressing the precedent of the military and purging the classical Ba'athist leadership of the old guard, including Michel Aflaq and Salah al-Din al-Bitar. The far-left neo-Ba'athist regime in Syria, which was influenced by various Marxist ideological schools, espoused radical leftist doctrines such as revolutionary socialism abandoned pan-Arabism, sought to strengthen ties with the Soviet Union, and came into conflict with Arab nationalists such as Nasserists and the Iraqi Ba'athists, particularly Saddamists, with whom they maintained a bitter rivalry. From their seizure of power in the Syrian Arab Republic as a result of the 1963 Syrian coup d'état, neo-Ba'athist officers purged traditional civilian elites to establish a military dictatorship operating along totalitarian lines.

Far-left politics encompasses a range of ideologies, such as anarchism, communism, Maoism, Leninism, Stalinism and Marxism, that are situated on the leftmost end of the political spectrum. The term is also used to describe various forms of authoritarianism and characterize groups that advocate revolutionary socialism, communist ideologies, anti-capitalism, anti-imperialism and anti-globalisation. Far-left terrorism consists of terrorism that is engaged in by extremist, militant, or insurgent groups that attempt to realize their ideals through political violence rather than democratic processes.

The Party of Left Socialist-Revolutionaries-Internationalists (Russian: Партия левых социалистов-революционеров-интернационалистов, romanized: Partiya levykh sotsialistov-revolyutsionerov-internatsionalistov) was a revolutionary socialist political party formed during the Russian Revolution.

In 1917, the Socialist Revolutionary Party split between those who supported the Russian Provisional Government, established after the February Revolution and those who supported the Bolsheviks, who favoured the overthrow of the Provisional Government and the placing of political power in the hands of the Congress of Soviets. Those that continued to support the Provisional Government became known as the Right SRs while those who aligned with the Bolsheviks became known as the Left Socialist-Revolutionaries or Left SRs (Russian: левые эсеры, romanized: leviye esery). After the October Revolution, the Left SRs formed a coalition government with the Bolsheviks from November 1917 to March 1918, but resigned its position in government after the signing of the Treaty of Brest-Litovsk. The Central Committee of the Left SRs ultimately ordered the assassination of Wilhelm von Mirbach in an attempt to cause Russia to re-enter World War I and launched an ill-fated uprising against the Bolsheviks shortly after. Most members of the Left SRs were promptly arrested, though the majority that opposed the uprising were steadily released and allowed to retain their positions in the Soviets and bureaucracy. However, they were unable to reorganize the party, which gradually splintered into multiple pro-Bolshevik parties – all of which would merge with the Russian Communist Party (Bolsheviks) by 1921.

Reformism is a political tendency advocating the reform of an existing system or institution – often a political or religious establishment – as opposed to its abolition and replacement via revolution.

Within the socialist movement, reformism is the view that gradual changes through existing institutions can eventually lead to fundamental changes in a society's political and economic systems. Reformism as a political tendency and hypothesis of social change grew out of opposition to revolutionary socialism, which contends that revolutionary upheaval is a necessary precondition for the structural changes necessary to transform a capitalist system into a qualitatively different socialist system. Responding to a pejorative conception of reformism as non-transformational, philosopher André Gorz conceived non-reformist reform in 1987 to prioritize human needs over capitalist needs.

Parcham (Pashto/Dari: پرچم, lit. 'banner' or 'flag') was the more moderate socialist faction of the People's Democratic Party of Afghanistan (PDPA) led by Afghan communist politician Babrak Karmal. It was later turned into the Watan (Homeland) Party of Afghanistan with a more Islamic outlook under Mohammed Najibullah. The faction was formed directly after the founding of the Party in 1965 following ideological splits in the PDPA. While the Parchamites stressed the need for swift social-economic reforms to achieve revolution, this was in direct contrast with their PDPA rivals, the Khalqists, who sought an immediate and violent overthrow of the government. Karmal believed that Afghanistan was not developed enough for a Leninist revolutionary approach and instead sought a patriotic and anti-imperialist united front to take the next steps toward revolution.

The Polish Workers' Party (Polish: Polska Partia Robotnicza, PPR) was a communist party in Poland from 1942 to 1948. It was founded as a reconstitution of the Communist Party of Poland (KPP) and merged with the Polish Socialist Party (PPS) in 1948 to form the Polish United Workers' Party (PZPR). From the end of World War II the PPR led Poland, with the Soviet Union exercising moderate influence. During the PPR years, the centers of opposition activity were largely diminished, and a socialist system was established in the country.

Arriving from the Soviet Union, a group of Polish communists was parachuted into occupied Poland in December 1941. With Joseph Stalin's permission, in January 1942 they established the Polish Workers' Party, a new communist party. The PPR established a partisan military organization Gwardia Ludowa, later renamed Armia Ludowa. In November 1943, Władysław Gomułka became secretary (chief executive) of the Central Committee of the PPR. On 1 January 1944 the party created the State National Council (KRN), proclaimed to be a wartime parliament of Poland; the body was chaired by Bolesław Bierut. In June 1944 the Union of Polish Patriots, a rival to the PPR Polish-communist organization operating in the Soviet Union, recognized the KRN as "the true representation of the Polish nation". The PPR was initially a small party with marginal support; it grew because of its alliance with the victorious Soviet Union.
