The European interwar period refers to the time between the end of World War I in 1918 and the beginning of World War II in 1939. This era was marked by significant political, economic, and social upheaval as countries attempted to recover from the devastation of the war, deal with the harsh terms of the Treaty of Versailles, and confront the rise of totalitarian regimes. The interwar period saw a struggle between democracy and authoritarianism, economic instability, and cultural transformation across Europe.
