A workers' uprising occurs in Kyiv, Ukraine (then part of the Russian Empire), and establishes the Shuliavka Republic.

Workers in Kyiv stage an uprising and establish the short-lived Shuliavka Republic during the 1905 Russian Revolution.
Amid the 1905 Russian Revolution, workers in Kyiv's Shuliavka district rose up against Tsarist authorities on December 11, 1905. They seized government buildings and proclaimed the autonomous Shuliavka Republic. Organized by socialist activists, the rebels formed workers' councils to administer the area. The uprising reflected growing discontent over exploitation, political repression, and national inequality. Imperial troops swiftly regained control, arresting leaders and dismantling the republic. Though brief, the Shuliavka Republic became a symbol of popular resistance in the Russian Empire. The event foreshadowed larger revolutionary movements that would culminate in the revolutions of 1917.
