The Crimson Coalition, rooted in collectivist ideals, emerges from worker and soldier dissatisfaction with living conditions and economic inequality amid massive industrialization. Influenced by Western collectivist thinkers, the movement originates from a resistance act during the conflict with the Pact. As mobilization intensifies, soldiers and workers rebel against harsh conditions, sparking a revolt. Local support thwarts the Tsarist army's attempts to suppress the rebellion, drawing collective intellectuals to the cause.

As chaos spreads, the Tsarist generals, losing faith in their local army, recall troops from the front. However, reinforcements and local sabotage delay the loyalist forces. When loyalists arrive, partisans face seasoned troops, resulting in a hard-fought conflict. Despite initial success, the Tsarist army regains control, executing revolt leaders. Unexpectedly, reinforcements from the Southern Novgorian Fleet bolster the remaining partisans, leading to a shift in favor.

Suebian diplomacy intervenes, striking a deal: weapons and supplies from Suebia in exchange for the Crimson Coalition opposing Tsarist troops. The movement gains momentum, attracting workers and soldiers from neighboring regions. Internal divisions arise within the Coalition, with differing visions for its future. As territories fall under Crimson control, internal conflicts intensify, leading to factionalism.

Amid internal strife, leaders like Irina Volkova unite the Coalition under a core principle: targeting the owners of production factors for wealth redistribution. A new policy emerges, emphasizing worker-led governance. Volkova's extreme faction advocates global liberation and a perpetual revolution. Internal dissenters are eliminated, solidifying her leadership.

Meanwhile, Tsarist forces organize the Loyalist army in Cossaria, planning to push back the Crimson Coalition. Irina, now de facto leader, reorganizes the Coalition based on her faction's principles, achieving victories against the Tsarist forces. Her strategy extends the movement's influence to Fenghua and even the United States of Ameria, where a syndicalist variant of the Crimson Coalition gains ground.
