One significant outcome of the Treaty of Trianon, signed in 1920, was the drastic reduction of Hungary's territory and population, leading to considerable national and ethnic tensions. Following World War I, the treaty forced Hungary to cede over two-thirds of its land to neighboring countries, including Romania, Slovakia, and Yugoslavia. This territorial loss had profound implications on the Hungarian economy and national identity, fostering feelings of resentment and betrayal among Hungarians. The treaty also set the stage for irredentism, as many Hungarians sought to reclaim the territories lost in the aftermath, influencing regional politics for decades.
