With a land area of 93,030 square kilometers, Hungary is a country in Central Europe. It measures about 250 kilometers from north to south and 524 kilometers from east to west. It has 2,258 kilometers of boundaries, shared with Austria to the west, Serbia, Croatia and Slovenia to the south and southwest, Romania to the southeast, the Ukraine to the northeast, and Slovakia to the north.
Hungary's modern borders were first established after World War I when, by the terms of the Treaty of Trianon in 1920, it lost more than 71% of what had formerly been the Kingdom of Hungary, 58.5% of its population, and 32% of the Hungarians. With the aid of Nazi Germany, the country secured some boundary revisions at the expense of parts of Slovakia in 1938, Carpatho-Ukraine in 1939, Romania in 1940 and Yugoslavia in 1941. However, Hungary lost these territories again with its defeat in World War II. After World War II, the Trianon boundaries were restored with a small revision that benefited Czechoslovakia.
Most of the country has an elevation of fewer than 200 meters. Although Hungary has several moderately high ranges of mountains, those reaching heights of 300 meters or more cover less than 2% of the country. The highest point in the country is Kékes (1,014 m) in the Mátra Mountains northeast of Budapest. The lowest spot is 77.6 meters above sea level, located in the south of Hungary, near Szeged.
The major rivers in the country are the Danube and Tisza. The Danube also flows through parts of Germany, Austria, Slovakia, Serbia, and Romania.It is navigable within Hungary for 418 kilometers. The Tisza River is navigable for 444 kilometers in the country. Less important rivers include the Drava along the Croatian border, the Rába, the Szamos, the Sió, and the Ipoly along the Slovakian border. Hungary has three major lakes. Lake Balaton, the largest, is 78 kilometers long and from 3 to 14 kilometers wide, with an area of 592 square kilometers. Hungarians often refer to it as the Hungarian Sea. It is Central Europe's largest freshwater lake and an important recreation area. Its shallow waters offer good summer swimming, and in winter its frozen surface provides excellent opportunities for winter sports. Smaller bodies of water are Lake Velence (26 square kilometers) in Fejér County and Lake Fertő (Neusiedler See--about 82 square kilometers within Hungary).
