Raška is a geographical and historical region of Serbia. Initially a small borderline district between early medieval Serbia and Bulgaria, since the mid-12th century became the center of the Grand Principality of Serbia and of the Serbian Kingdom. From that period the name of Raška became associated with the state of Serbia, eventually covering the south-western parts of modern Serbia, and historically also including north-eastern parts of modern Montenegro, and some of the most eastern parts of modern Bosnia and Herzegovina, and its southern part also corresponds to the modern region of Sandžak.

Serbia, officially the Republic of Serbia, is a landlocked country at the crossroads of Southeast and Central Europe, located in the Balkans and the Pannonian Plain. 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. Serbia claims a border with Albania through the disputed territory of Kosovo. Serbia has about 6.6 million inhabitants, excluding Kosovo. Its capital Belgrade is also the largest city.
