Nationalism in Soviet Republics refers to the strong sense of pride and identity that various ethnic groups within the Soviet Union developed during its existence, leading to a demand for greater autonomy or independence. This feeling was fueled by historical grievances, cultural differences, and the desire for self-determination, becoming particularly pronounced as the Soviet Union weakened in the late 20th century. As the central authority of Moscow diminished, these nationalist sentiments played a crucial role in the eventual dissolution of the USSR.
