It formally ended World War I between most of the Allies of World War I and the Kingdom of Hungary. French diplomats played the major role in designing the treaty, with a mind to establishing French-led coalition of the newly formed nations. It regulated the status of the independent Hungarian state and defined its borders generally within the ceasefire lines established in November–December 1918 and left Hungary as a landlocked state that included 93,073 square kilometres (35,936 sq mi), 28% of the 325,411 square kilometres (125,642 sq mi) that had constituted the pre-war Kingdom of Hungary. The new Kingdom had a population of 7.6 million, 36% compared to the pre-war kingdom's population of 20.9 million. Though the areas that were allocated to neighbouring countries had a majority of non-Hungarians, in them lived 3.3 million Hungarians – 31% – who were now in a minority status. The treaty limited Hungary's army to 35,000 officers and men, and the Austro-Hungarian Navy ceased to exist. These decisions and their consequences has been the cause of deep resentment in Hungary ever since.
