The Finnish Civil War erupted in early 1918 amid escalating tensions following Finland's declaration of independence from Russia in December 1917. Finland was experiencing significant sociopolitical changes, with deep divides forming between the socialist Red Guards, who sought workers' rights and social reforms, and the White Guards, favoring conservative and capitalist ideologies. On January 26, 1918, the Red Guards showcased their resolve by climbing to the tower of the Helsinki Workers' Hall, a key site for the socialist movement, and hanging a red lantern that would symbolize their commitment to achieving their goals through the conflict that was about to unfold.

This symbolic act not only marked the Red Guards' readiness for war but also sent a clear message that they would assert their presence and ideology during the turbulent days ahead. The red lantern indicated solidarity and defiance against ruling authority from the emerging Finnish government and its supporters. As the war progressed, it would lead to violent confrontations, including battles across various regions of Finland, impacting civilians and shaping the future of the nation.

The Finnish Civil War was characterized by its brutal nature, including widespread violence and repression on both sides. The Red Guards represented the working class and leftist movements, while the White faction comprised former aristocrats and military personnel. The conflict lasted until May 1918, ultimately resulting in a White victory, leading to the establishment of a conservative government. The symbolism of the red lantern on that day became an enduring image of the struggle for workers' rights and socialist ideology in Finland's historical landscape.
