The Treaty of Trianon is the peace treaty formed in 1920 by the Allies of World War I on one side, and Hungary, on the other.[1][2][3][4]

Hungary lost much of its land to neighbouring countries,[5] such as Romania, Czechoslovakia and Yugoslavia. Hungary was partitioned, lost two thirds of her territory, and lost one-third of her Hungarian population. This brought irredentism. Hungary also had to pay World War I reparations. The treaty limited the size of the Hungarian army.
