(1527), his commander Radoslav Čelnik ruled Syrmia as an Ottoman and Habsburg vassal until 1532, when he retreated to Slavonia with the Ottoman conquest. Many of the Syrmian Serbs then settled the Kingdom of Hungary. A 1542 document describes that "Serbia" stretched from Lipova and Timișoara to the Danube, while a 1543 document that Timișoara and Arad being located "in the middle of Rascian land" (in medio Rascianorum). At that time, the majority language in the region between Mureș and Körös was indeed Serbian. Apart from Serbian being the main language of the Banat population, there were 17 Serbian monasteries active in Banat at that time. The territory of Banat had received a Serbian character and was called "Little Rascia". In early 1594, the Serbs in Banat rose up against the Ottomans, during the Long Turkish War (1593–1606) which was fought at the Austrian-Ottoman border in the Balkans. The Serbian patriarchate and rebels had established relations with foreign states, and had in a short time captured several towns, including Vršac, Bečkerek, Lipova, Titel and Bečej. The rebels had, in the character of a holy war, carried war flags with the icon of Saint Sava, the founder of the Serbian Orthodox Church and an important figure in medieval Serbia. The war banners had been consecrated by Patriarch Jovan Kantul, and the uprising had been aided by Serbian Orthodox metropolitans Rufim Njeguš of Cetinje and Visarion of Trebinje. Because of the substantial number of Serbs (Rascians), who belonged to the Ottoman social and fiscal category of vlachs () parts of the Sanjak of Pakrac and Sanjak of Požega were also referred to as Mala Vlaška (). In the 17th and early 18th century, the territory of lower Slavonia was called Mala Raška (), due to its large number of Serbs. In 17th-century Habsburg usage, the term "Rascian" referred most commonly to the Serbs who lived in Habsburg-controlled territory, then more generally to Orthodox Serbs, wherever they lived, and then more generally still to speakers of Serbian language. Throughout the 17th century, former counties of Požega, Baranya and Syrmia were often mentioned as "Rácország" (Hungarian term for the region of Rascians). The Emperor's so-called "Invitatorium" in April 1690, for example, was addressed to Arsenije III as "Patriarch of the Rascians", but Austrian court style also distinguished between "Catholic Rascians" and "Orthodox Rascians". In 1695, Emperor Leopold issued a protective diploma for Patriarch Arsenije
