The result of the Treaty of Trianon, signed in 1920 following World War I, was the significant territorial reduction of Hungary and the establishment of new boundaries in Central Europe. The treaty imposed harsh conditions on Hungary, which lost about two-thirds of its territory and population to neighboring countries, including Romania, Czechoslovakia, and Yugoslavia. This territorial loss caused considerable economic and social challenges for Hungary and fostered resentment towards the treaty, contributing to nationalist sentiments and political instability in the region for years to come. The Treaty of Trianon has had a lasting impact on Hungarian national identity and its relations with neighboring countries.
