Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. Poland borders it to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 square kilometers (19,000 sq mi), with a population of over 5.4 million. The capital and largest city is Bratislava, while the second-largest city is Košice.
Slovakia's name, in theory, means the "Land of the Slavs" (Slovensko in Slovak stemming from the older form Sloven/Slovienin). As such, it is a cognate of the words Slovenia and Slavonia.
