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).
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).
[4] The territory inhabited primarily by the Serbs in the Habsburg monarchy was called Latin: Rascia; Serbian: Raška/Рашка; Hungarian: Ráczság,[5] Ráczország,[6] rácz tartomány,[6]; German: Ratzenland, Rezenland.
[9] Having picked the losing side in the Hungarian civil war, the Branković dynasty were stripped of their estates in Hungary upon Matthias Corvinus' coronation in 1458.
The settlement of Serbs in Syrmia, Bačka, Banat and Pomorišje strengthened the Hungarian hold of these sparse areas, most exposed to Ottoman expansion.
Following the Ottoman conquest, a large part of the Serbian nobility were killed, while what survived crossed into Hungary, bringing their subjects, including many farmer families, with them.
Matthias Corvinus complained in a letter from 1462 that 200,000 peoples during the previous three years had been taken from his country by Turks, this information was used as a reference for Serbian migration to Hungary.
The Serbian patriarchate and rebels had established relations with foreign states,[22] and had in a short time captured several towns, including Vršac, Bečkerek, Lipova, Titel and Bečej.
The war banners had been consecrated by Patriarch Jovan Kantul,[22] and the uprising had been aided by Serbian Orthodox metropolitans Rufim Njeguš of Cetinje and Visarion of Trebinje.
In 1695, Emperor Leopold issued a protective diploma for Patriarch Arsenije and the Serb people, whom he called "popolum Servianum" and "Rasciani seu Serviani".
[27] During the Kuruc War (1703–1711) of Francis II Rakoczi, the territory of present-day Vojvodina was a battlefield between Hungarian rebels and local Serbs who fought on the side of the Habsburg Emperor.
Darvas, the prime military commander of the Hungarian rebels, which fought against Serbs in Bačka, wrote: We burned all large places of Rascia, on the both banks of the rivers Danube and Tisa.
