Serbia, officially the Republic of Serbia is a country in the Central and Southeast Europe. It is situated in the southern Pannonian Plain and central Balkans, and 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; while claiming a border with Albania through the disputed territory of Kosovo. Serbia has a population of roughly 7 million, with Belgrade as its capital and largest city.
Continuously inhabited since the Paleolithic Age, the territory of modern-day Serbia faced Slavic migrations 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. The Serbian Kingdom obtained recognition by the Holy See and Constantinople in 1217, reaching its territorial apex in 1346 as Serbian Empire.
