Question

Quizplus · Accepted Answer

Rampant nationalism, particularly in the successor states of the former Austro-Hungarian Empire and Ottoman Empire, contributed to ethnic and territorial disputes that destabilized the region. These tensions were often exploited by authoritarian leaders and fascist movements in the 1920s and 1930s. The other options listed (reimposition of empires, liberal democratic reforms, and coalition governments) may have also played a role in certain contexts, but they were generally less significant factors than nationalism in creating instability in the successor states.
