According to the 7th-century Miracles of Saint Demetrius, Avars gave the region of Syrmia to a Bulgar leader named Kuber circa 680.Salan's residence was Titel, while that of Glad was possibly in the rumoured rampart of Galad or perhaps in the Kladovo (Gladovo) in eastern Serbia.Glad's descendant was the duke Ahtum, another local ruler from the 11th century who opposed the establishment of Hungarian rule over the region.Bunardžić dated Avar-Bulgar graves excavated in Čelarevo, containing skulls with Mongolian features and Judaic symbols, to the late 8th and 9th centuries.)[citation

administration until the 16th century (Following periods of Ottoman and Habsburg administrations, Hungarian political dominance over most of the region was established again in 1867 and over entire region in 1882, after abolition of the Habsburg Military Frontier).[citation needed] The regional demographic balance started changing in the 11th century when Magyars began to replace the local Slavic population.But from the 14th century, the balance changed again in favour of the Slavs when Serbian refugees fleeing from territories conquered by the Ottoman army settled in the area.In 1526 Jovan Nenad, a leader of Serb mercenaries, established his rule in Bačka, northern Banat and a small part of Syrmia.Taking advantage of the extremely confused military and political situation, the Hungarian noblemen from the region joined forces against him and defeated the Serbian troops in the summer of 1527.[11] At the beginning of Habsburg rule, most of the region was integrated into the Military Frontier, while western parts of Bačka were put under civil administration within the County of Bač.[citation needed] During the 1848–49 revolutions, Vojvodina was a site of a war between Serbs and Hungarians, due to the opposite national conceptions of the two peoples.[12] The head of the metropolitanate of Sremski Karlovci, Josif Rajačić, was elected patriarch, while Stevan Šupljikac was chosen as first voivod (duke).[citation needed] Following the Habsburg-Russian and Serb victory over the Hungarians in 1849, a new administrative territory was created in the region in November 1849, in accordance with a decision made by the Austrian emperor.By this decision, the Serbian autonomous region created in 1848 was transformed into the new Austrian crown land known as Voivodeship of Serbia and Banat of Temeschwar.On 25 November 1918, the Great People's Assembly of Serbs, Bunjevci and other Slavs in Banat, Bačka and Baranja in Novi Sad proclaimed the unification of Vojvodina (Banat, Bačka and Baranja) with the Kingdom of Serbia (The assembly numbered 757 deputies, of which 578 were Serbs, 84 Bunjevci, 62 Slovaks, 21 Rusyns, 6 Germans, 3 Šokci, 2 Croats and 1 Hungarian).Apart from the core territories of Vojvodina and Baranja, it included significant parts of Šumadija and Braničevo regions south of the Danube (but not the capital city of Belgrade).Between 1941 and 1944, during World War II, Nazi Germany and its allies, Hungary and the Independent State of Croatia, occupied Vojvodina and divided it.A smaller Danube Banovina (including Banat, Šumadija, and Braničevo) was designated as part of the area governed by the Military Administration in Serbia.In total, Axis occupational authorities killed about 50,000 citizens of Vojvodina (mostly Serbs, Jews and Roma) while more than 280,000 people were interned, arrested, violated or tortured.[21][22][23][24] In 1942, in the Novi Sad Raid, a military operation carried out by the Királyi Honvédség, the armed forces of Hungary, during World War II, after occupation and annexation of former Yugoslav territories.[35][36] Under the rule of Serbian president Slobodan Milošević, a series of protests against Vojvodina's party leadership took place during the summer and autumn of 1988, which forced it to resign.[citation needed] The Vojvodina provincial assembly adopted a new statute on 15 October 2008, which, after being partially amended, was approved by the Parliament of Serbia.The seven districts are further subdivided into 37 municipalities and the 8 cities of Kikinda, Novi Sad, Subotica, Zrenjanin, Pančevo, Sombor, Sremska Mitrovica, and Vršac.During the NATO bombing in the spring of 1999, the RT Novi Sad building of 20 thousand square meters was completely destroyed along with its basic production and technical premises .Traditionally, it has always been a significant part of the local economy and a generator of positive results, due to the abundance of fertile agricultural land which makes up 84% of its territory.Vojvodina pays particular attention to interregional and cross-border economic cooperation, as well as to implementation of priorities defined within the EU Strategy for the Danube Region.Tourist destinations in Vojvodina include well known Orthodox monasteries on Fruška Gora mountain, numerous hunting grounds, cultural-historical monuments, different folklores, interesting galleries and museums, plain landscapes with a lot of greenery, big rivers, canals and lakes, sandy terrain Deliblatska Peščara ("the European Sahara"), etc.
