Rascians ( / Raši, Rašani; ) was a historical term for Serbs. The term was derived from the Latinized name for the central Serbian region of Raška (; ). In medieval and early modern Western sources, exonym Rascia was often used as a designation for Serbian lands in general, and consequently the term Rasciani became one of the most common designations for Serbs. Because of the increasing migratory concentration of Serbs in the southern Pannonian Plain, since the late 15th century, those regions also became referred to as Rascia, since they were largely inhabited by Rasciani (Rascians). Among those regions, term Rascia (Raška) was most frequently used for territories spanning from western Banat to central Slavonia, including the regions of Syrmia, Bačka, and southern Baranja. From the 16th to the 18th century, those regions were contested between the Ottoman Empire and the Habsburg monarchy, and today they belong to several modern countries (Serbia, Romania, Hungary, Croatia). In a wider perspective, the term was also used for some other related South Slavic groups of the Habsburg Monarchy, such as the Catholic Bunjevci and Šokci (designated as "Catholic Rascians"). Although they were certainly mostly Serbs, the term Rascians has wider meaning and includes all southern Slavs except Bulgarians. The reason for this is very mixed terminology of individual nations and ethnic groups immigrated to Hungary. They were distinguished by their religion as the "Catholic Rascians" Dalmatians, or as they are today called Bunjevci (which are they were originally from Dalmatia). People who were called Rascians later mostly self-identified as Serbs. In Hungary some Rascians saw themselves as Croats, mostly in villages of Tököl (Tukulja), Bátya (Baćin) and Dusnok (Dušnok). Etymology The demonym ; ; ; , anglicized as "Rascians". The name, primarily used by Hungarians and Germans, derived from the pars pro toto "Raška" (Rascia), a medieval Serbian region.

History The defeats at the hand of the Ottoman Empire in the late 14th century forced the Serbs to rely on the neighbouring states, especially Hungary. After the Ottoman conquest of Serbian territories in 1439, Despot Đurađ Branković fled to the Kingdom of Hungary where he was given a large territory in southern Pannonia, while his son Grgur ruled Serbia as an Ottoman vassal until his removal in 1441. Đurađ's daughter Katarina of Celje (1434–56) held
