Serbia [SEP] Introduction
Serbia (, ), officially the Republic of Serbia (, ), is a landlocked country situated at the crossroads of Central and Southeast Europe in the southern Pannonian Plain and the central Balkans. It borders Hungary to the north, Romania to the northeast, Bulgaria to the southeast, North Macedonia to the south, Croatia and Bosnia and Herzegovina to the west, and Montenegro to the southwest. The country claims a border with Albania through the disputed territory of Kosovo. Serbia's population numbers approximately seven million. Its capital, Belgrade, ranks among the largest and oldest citiеs in southeastern Europe. Continuously inhabited since the Paleolithic Age, the territory of modern-day Serbia faced Slavic migrations to Southeastern Europe in the 6th century, establishing several regional states in the early Middle Ages at times recognised as tributaries to the Byzantine, Frankish and Hungarian kingdoms.
