Executive summary

The 1917 Russian Revolution served both as an inspiration and as a cautionary mirror for Western socialist and social-democratic parties: it energized revolutionary factions worldwide while simultaneously pushing many established Western parties toward democratic, reformist politics to distance themselves from Bolshevik methods and to retain respectability within liberal systems [1] [2]. Its existence reshaped political language—“socialism” split into revolutionary communism and parliamentary, democratic socialism—and that terminological split explains why Western parties would adopt the label “democratic socialist” in the decades that followed [3] [2].

1. The revolution as a global stimulant to socialist identity

The Bolshevik seizure of power in October 1917 became a dramatic demonstration that a socialist party could overthrow an existing order, and that example electrified left movements worldwide, raising class consciousness and providing a model that some Western organizations sought to emulate or learn from [1] [4]. Contemporary Marxists and revolutionary socialists explicitly treated 1917 as a turning point that validated the possibility of proletarian rule and gave fresh urgency to calls for political transformation across Europe and beyond [1] [5].

2. A painful schism: revolutionary versus parliamentary socialism

The events in Russia sharpened pre-existing tensions inside socialist internationals between those who favored immediate revolutionary rupture and those who argued for gradual, parliamentary routes to social change; the Bolsheviks’ methods and outcomes crystallized these debates and pushed many Western parties to define themselves against Bolshevik tactics [6] [7]. Scholarly accounts emphasize that while revolutionary rhetoric inspired radicals, most mass social-democratic parties in Western Europe increasingly accommodated existing political regimes and rejected insurrectionary strategy after 1917 [2].

3. Democratic socialism as a defensive and aspirational label

Western parties that called themselves democratic socialists did so in a context shaped by 1917: the label signalled commitment to socialist ends but through democratic institutions rather than one-party seizure, a split that reflected both ideological conviction and a desire to avoid the political delegitimization that came with association with Soviet-style centralism [3] [2]. The October example also forced socialists to reckon publicly with governance questions—how to combine planning, welfare and popular participation without reproducing the over-centralization and lack of democratic checks critics associated with the Soviet model [3].

4. Western governments’ reactions shaped party strategies and public narratives

The new Soviet state’s radical reforms and the ensuing geopolitical threat unnerved western democracies and affected domestic politics: fear of Bolshevism helped harden anti-communist currents while also prompting reforms—state planning and welfare measures in some Western countries—that social democrats could claim as democratic alternatives to revolution [8] [3]. Thus democratic socialism operated both as critique of capitalism and as a palatable policy program that could undercut revolutionary appeals while preserving democratic legitimacy [3] [9].

5. Enduring ambiguities and the limits of the record

Historians differ over the balance between inspiration and deterrence that 1917 produced: some left currents celebrated the revolution as proof of Marxism in practice, while others argued it demonstrated the perils of centralization and authoritarianism [1] [3]. The provided sources document broad impacts—ideological stimulus, organizational splits, Western welfare responses—but do not catalogue every party’s name-change or internal deliberations; specific domestic histories of particular Western parties require targeted archival or national scholarship beyond these general accounts [2] [10].
