Interwar Europe's democratic collapses (1922-1939)
New democracies across central and eastern Europe collapsed into authoritarianism within a generation of World War I: Italy in 1922, Poland in 1926, Germany in 1933. Emergency powers and rule-of-law erosion preceded each takeover.
A continent-wide wave of authoritarian rule followed within two decades.
The sequence from legal erosion to violent conflict shaped post-1945 institution-building.
The report warns that some forms of democratic decline are associated with a greater risk of violent conflict, echoing the interwar pattern where legal erosion preceded state-on-state war.
