Ba?ka (Serbian: / Ba?ka, pronounced [bâ:tka:]; Hungarian: Bácska, pronounced ['ba:tk?]) is a geographical and historical area within the Pannonian Plain bordered by the river Danube to the west and south, and by the river Tisza to the east. It is divided between Serbia and Hungary. Most of the area is located within the Vojvodina region in Serbia and Novi Sad, the capital of Vojvodina, lies on the border between Ba?ka and Syrmia. The smaller northern part of the geographical area is located within Bács-Kiskun County, in Hungary.
The name of the region in Serbian is Ba?ka or and in Hungarian is Bácska. In other languages of the region, the name is similar: Ba?ka in Croatian and Bunjevac, Bá?ka in Slovak, (Ba?ka) in Rusyn, and Batschka in German.
According to Serbian historians, Ba?ka is a typical Slavic name form, created from "Ba?" (name of historical town in Ba?ka) and suffix "ka" (which designates "the land that belongs to Ba?"). There are many other similar name forms used in Serbian and other Slavic languages[original research?], for example ?ajka?ka, Srpska, Hrvatska (Croatia), Timo?ka Krajina, Bugarska (Bulgaria), Polska (Poland), etc.
The name of "Ba?" (Bács) town itself is of uncertain origin and its existence was recorded among Vlachs, Slavs and Hungarians in the Middle Ages. The origin of the name could be Paleo-Balkanic,Romanian, Slavic, or Old Turkic.
According to Hungarian historians, the denominator of the landscape may have been the first bailiff of Ba? (Bács) castle, and the name one which can be rendered probable it Old Turkic baya derives from a dignity name.
In the 17th and 18th century, due to the large number of Serbs who lived in Ba?ka, this region was called »Raczorszag« (Hungarian name, which means "the Serb country" in English). Sometimes, the Hungarians used name Délvidék ("the southern or lower country") for a wider imprecisely defined geographical area, which, according to 19th century view also included Ba?ka. However, according to other Hungarian sources, Ba?ka was rather seen as part of Alföld.
Through history, Ba?ka has been a part of Dacia, the Kingdom of the Iazyges, the Hun Empire, the Gepid Kingdom, the Avar Khanate, the First Bulgarian Empire, the Great Moravia, the Kingdom of Hungary, the Serb realm of Jovan Nenad, the Ottoman Empire, the Habsburg Monarchy, the Austrian Empire, Austria-Hungary, the Kingdom of Serbia, the Kingdom of Serbs, Croats and Slovenes, the Kingdom of Yugoslavia, the Socialist Federal Republic of Yugoslavia, the Federal Republic of Yugoslavia, Serbia and Montenegro, and since 2006, it has been part of an independent Republic of Serbia. The smaller northern part of the region was part of the short-lived Serb-Hungarian Baranya-Baja Republic (in 1921) and part of independent Hungary since 1921.
People have inhabited the region of Ba?ka since Neolithic times. Indo-European peoples settled in this region in three migration waves dated in 4200 BC, 3300 BC, and 2800 BC respectively. The earliest historical inhabitants of the region were probably Illyrian tribes. Later, other Indo-European peoples, including Dacians, Celts, Sarmatians (Iazyges) and Gepids were recorded as inhabitants of Ba?ka.
Slavs, the ancestors of contemporary Serbs, settled today's Ba?ka in the 6th and 7th centuries, before part of them subsequently migrated to the Balkans. In the 9th century the territory of Ba?ka was part of Bulgarian Empire. Salan, a Bulgarian voivod (duke), was a ruler in this territory and his capital city was Titel. In the early 10th century, Hungarians defeated Salan, and his duchy came under Hungarian rule.
At the turn of the first millennium, during the administration of the medieval Kingdom of Hungary by Stephen I of Hungary, two counties (comitatus) were formed in this land. Bács County in the south, with city of Bács (now Ba?) as its administrative centre and Bodrog County in the western and central territories with the historical city of Bodrogvár as capital (near the presenr-day village of Ba?ki Mono?tor). The two countries were later united to form Bács-Bodrog County. In 1085 King Ladislaus I made Bács the seat of the Archbishopric of Kalocsa-Bács. The first archbishop, Fabian (1085-1103) helped the king in the course of the campaign against Croatia and was rewarded with the title. According to Serbian sources, Ilija Vid, the first known prefect of Bacsensis County was recorded in 1068 and he was an ethnic Serb. In this time, the region was populated by both, Slavs and Hungarians. Serbian historian Dr. Milenko Pali? also mentions that prefect Vid was an ethnic Serb and that he, together with two other ethnic Serbs whose names were Ilija and Radovan, participated in dynastic struggles in the Kingdom of Hungary, in the end of the 11th century.[verification needed] According to Hungarian authors, prefect Vid belonged to the Gutkeled genus, but there is a possibility that he was a fictitious person. In 1169, canons from the knighthood Order of the Holy Sepulchre built a small church in Bács in the Romanesque style. They used some building materials from much older previous edifices. Franciscans took over the church in 1300. In the second half of the 14th century, the Franciscans expanded it, forming a monastery. Today the Fanciscian monastery of Bács is the oldest church building in present-day Vojvodina. In the early 13th century Ugrin Csák, Archbishop of Kalocsa, founded a hospital in Bács, as the first such facility in this part of Europe. Pope Gregory IX wrote about the "Ba?ka hospital" in 1234, as being open for the sick and poor. At the beginning of the fourteenth century the town of Bács prospered during the rule of king Charles Robert I, who started building the modern fortress in 1338-42 at the site of the earlier hillfort. From the 15th century, it became the most important Hungarian defense point against the invading Ottoman forces.
In 1526 the Kingdom of Hungary was defeated in the Battle of Mohács by the Ottoman Empire. During the revolt of the Rascians, Ba?ka became (from 1526-27) the central region of an independent, short-lived Serbian pseudostate, which existed in the territory of present-day Vojvodina. The ruler of this state was the self-appointed Emperor Jovan Nenad and his capital city was Subotica. After Jovan Nenad was defeated and killed, his state collapsed and Ba?ka, for a short time, came again under Hungarian administration. Soon, the region became part of the Ottoman Empire.
After the Ottoman conquest, most of the previously decisive Hungarian majority population have fled (in the 16th-17th centuries). The relatively dense populated and prosperous southern counties of the Kingdom were devastated and became mostly abandoned and uninhabited. In this period begun the intense settlement of the Serbs and other South Slavs from the Ottoman ruled central Balkans. They were military engaged in the borderlands by the both sides. This resulted in radical changes of the population structure. Ba?ka was part of the Sanjak of Segedin (Szeged), and the region was mainly populated with Serbs (who were in an absolute majority) and Muslims.
During the Great Turkish War (1683-1699) near Senta in eastern Ba?ka took place one of the most decisive defeats in Ottoman history, the Battle of Zenta. Christian forces of the Holy League (1684) led by Prince Eugene of Savoy in a surprise attack destroyed the Ottoman army crossing the river Tisza. The battle resulted in a spectacular victory for Austria. As a result in 1699 the Treaty of Karlowitz was signed, ending the Ottoman controll in much of Central Europe. All the lands of the Kingdom of Hungary (except for Banat and a small chunk of Eastern Slavonia) conquered by the Ottomans in the previous 150 years were returned. The Ba?ka became a possession of the Habsburg Monarchy. Bács-Bodrog County was established in the western parts of the region, while some other (mostly eastern) parts of the Ba?ka were incorporated into the Tisza-Maros section of Habsburg Military Frontier. After this part of the Military Frontier was abolished in 1751, these parts of Ba?ka were also included into Bacsensis county. The only part of Ba?ka which remained within the Military Frontier was ?ajka?ka, but it also came under civil administration in 1873.
According to the Austrian censuses from 1715-20, Serbs, Bunjevci, and ?okci comprised most of the region's population (97.6% of population according to 1715-1720 census data). There were only 530 or 1.9% Hungarians and 0.5% Germans. During the 18th century, the Habsburgs carried out an intensive colonisation of the area, which had low population density after the last Ottoman Wars, as much of the Serbian population had been decimated through warfare. Muslim population had almost entirely left or was expelled from the region and some of the Muslim refugees from this area settled in Ottoman Bosnia. The new settlers in Ba?ka were primarily Serbs who moved from Ottoman Balkans, Hungarians - returning to Ba?ka from all parts of the Habsburg Hungary, and Germans. Because many of the Germans came from Swabia, they were known as Donauschwaben, or Danube Swabians. Some Germans also came from Austria, and some from Bavaria and Alsace. Lutheran Slovaks, Rusyns, and others were also colonized but to a much smaller extent.
There was also an emigration of Serbs from the eastern parts of the region, which belonged to Military Frontier until 1751. After the abolition of the Tisa-Mure? section of Military Frontier, many Serbs emigrated from north-eastern parts of Ba?ka. They moved either to Russia (notably to New Serbia and Slavo-Serbia) or to Banat, where the Military Frontier was still needed.

In 1848 and 1849, Ba?ka was part of the Serbian Voivodship, a Serbian autonomous region within Austrian Empire, while between 1849 and 1860 it was part of the Voivodship of Serbia and Tami? Banat, a separate Austrian crown land (the official languages of the voivodship were German and Illyrian, i.e. Serbo-Croatian), the successor of the Serbian Voivodship. After 1860, when Voivodship of Serbia and Tami? Banat was abolished, the Bács-Bodrog County was again formed in the territory of Ba?ka. The county was part of the Kingdom of Hungary, which became one of two autonomous parts of Austria-Hungary in 1867. According to the 1910 census, the population of Ba?ka numbered 704,563 people and was composed of: 43.2% speakers of Hungarian (310,490), 28.1% speakers of South Slavic (Serbo-Croatian) language and 22.5% speakers of German. Linguistic composition of the region is partially different from ethnic composition since some ethnic Jews and bilingual South Slavs were in this census recorded as speakers of Hungarian language.
In early September 1914, several years before the end of the Austria-Hungary, in a town in the West Vojvodina Ba?ka region known as Zombor or Sombor of some 30,000 people, including 12,000 Serb-speakers, popular demonstrations demanded the removal of all shop signs in the Cyrillic alphabet. When an angry mob chased one Serb-speaking shopkeeper to his home for refusing to remove his Cyrillic sign, he responded by shooting at the demonstrators. The local military commander demanded the shopkeeper's immediate extradition, court martialed him and executed him on the spot. The court martial also designated twelve more affluent hostages from among the Serb-speaking population who would be "arrested and immediately executed by the military authorities" in the case of any obstruction or opposition shown by the local [Serb-speaking] population to the military authorities." This would presage the Serb genocide committed in the Independent State of Croatia during most of the Second World War.
At the end of October 1918, Austria-Hungary gradually dissolved and, with the Armistice of Villa Giusti of 3 November, officially capitulated to the Triple Entente. Following this capitulation, Slavs from Banat, Ba?ka and Baranja organized a new civil administration in these regions as well as their own military units known as People's Guard (Serbian: Narodna stra?a). The new civil administration was composed of local People's Boards (Serbian: Narodni odbori), which were subordinated to Serb People's Board (Serbian: Srpski narodni odbor) in Novi Sad. Military units of Serb People's Board also possessed aircraft from the Novi Sad Airport. After elections, which were organized between 18 and 24 November, Great People's Assembly of Serbs, Bunjevci and other Slavs of Banat, Ba?ka and Baranja (held on 25 November 1918) proclaimed unification of these regions with the Kingdom of Serbia. The assembly represented only a part of the whole population and did not met the principle of the self-determination of nations. It numbered 757 deputies, of which 578 were Serbs , 84 Bunjevci , 62 Slovaks , 21 Rusyn , 6 Germans , 3 ?okci , 2 Croats and 1 Hungarian , despite the fact that the absolute majority of the population of these regions was Hungarian and German. New administrative bodies of Banat, Ba?ka and Baranja (government and parliament) were also formed. Although, government in Belgrade accepted decision of unification with Serbia, it never recognized new provincial government. The provincial administration, however, was active until 12 March 1919, when it held its last session.
On 1 December 1918, the Kingdom of Serbia united with the State of Slovenes, Croats and Serbs to form new country named the Kingdom of Serbs, Croats, and Slovenes. Sovereignty of new kingdom was internationally recognized by the Treaty of Saint Germain in 1919. The Treaty of Trianon of 4 June 1920 defined the exact borders between the newly independent Hungary and the Kingdom of Serbs, Croats and Slovenes (which was later renamed the Kingdom of Yugoslavia) and original territory of Ba?ka was divided between these two countries. The northern part of the region was a separate county of Hungary (Bács-Bodrog) with seat in Baja, which was later incorporated into Bács-Kiskun county. The southern part of the region was within the District of Novi Sad of the Kingdom of Serbs, Croats, and Slovenes between 1918 and 1922, then was divided between Ba?ka Oblast and Belgrade Oblast, provinces (oblasts) of the kingdom, between 1922 and 1929. In 1929, it was incorporated into Danube Banovina, which was a province of the Kingdom of Yugoslavia.
Between 1820 and 1910, Hungarian speaking population in Ba?ka increased from 121,688 (31.5%) to 363,518 (44.75%). In the same time, percentage of South Slavs decreased from 44% in 1820 to 27% in 1910. 1921 census showed about 40,000 Hungarian speakers less than in census of 1910. This was especially case in Subotica where 1910 census recorded 55.587 speakers of Hungarian and 33,247 speakers of Bunjevac, while census of 1921 recorded 60,700 speakers of Serbo-Croatian and 26,750 speakers of Hungarian. This is explained by the fact that ethnic Bunjevci from Subotica who had knowledge of Hungarian language were listed as speakers of Hungarian by 1910 census. Between 1921 and 1931 census, number of Hungarian speakers in Ba?ka increased from 260,998 to 268,711. Slavic population increased by 91,800 inhabitants.
In 1941, Yugoslav Ba?ka was occupied by the Axis powers and attached to Horthy's Hungary (but was still internationally recognized as part of Yugoslavia). Before this occupation, according to 1931 census, Yugoslav Ba?ka had 784,896 inhabitants, of whom there were 284,865 Yugoslavs (Serbs, Croats, Bunjevci, ?okci), 268,711 Hungarians and 169,858 Germans. Hungarian occupation authorities expelled several thousands of Serbs from the region and settled ethnic Hungarians from other parts of Central Europe in their place, so that the Hungarian census of 1941 recorded different a demographic composition in the region. According to this census, the territory of Ba?ka had 789,705 inhabitants, of which 45.4% or[clarification needed] 47.2% were speakers of Hungarian language (not all of them native, however). During the occupation, Hungarian troops killed about 20,000 Serbs, Jews and Roma.
The occupation ended in 1944 and Yugoslav Ba?ka became part of the new Democratic Federal Yugoslavia (later the Socialist Federal Republic of Yugoslavia). Following the defeat of the Axis troops, most of the German population that lived in the area left the region together with German army. The smaller part of the German population (several thousands of people) that did not leave the area (mostly women, children and the elderly) were sent to prison camps, where many of them died of malnutrition and disease. After the war, members of the Yugoslav Partisan army also killed several tens of thousands of inhabitants of German, Hungarian and Serb ethnic origin (in whole of Vojvodina). Estimates about numbers of victims of the Partisans (in whole of Vojvodina) are between 17,000 and 56,000 killed Germans, between 4,000 and 40,000 Hungarians killed, and about 23,000-24,000 Serbs killed.
Together with eastern Syrmia, western Banat, and northern Ma?va, Yugoslav Ba?ka has been part of the Autonomous Province of Vojvodina since 1945. After 1992, Yugoslav Ba?ka was part of the Federal Republic of Yugoslavia (renamed Serbia and Montenegro in 2003), and since 2006 it has been part of the independent Republic of Serbia.

Ba?ka is a flat, fertile agricultural area within the larger Pannonian Plain, which was once the ancient Pannonian Sea. In Hungary, it is seen as a southern extension of the Great Alfold (itself part of the Pannonian Plain), while this designation is not used in Serbia where region is simply seen as a part of the Pannonian Plain. It lies between the River Danube to the west and south, and by the River Tisa (Tisza) to the east of which confluence is located near Titel in the South Ba?ka District of Serbia. The region is crisscrossed by parts of the Danube-Tisa-Danube Canal system which serves a variety of economic purposes. Almost all of Ba?ka is divided between Serbia and Hungary. However, there are small uninhabited pockets of the area on the left bank of the Danube which are de jure parts of Croatia according to the Badinter Commission; the disputed areas have been under de facto Serbian control since 1991.
Most of the territory and a vast majority of the population of Ba?ka is part of Serbia's Autonomous Province of Vojvodina. This area within Serbia is officially divided into the districts of Southern Ba?ka, Western Ba?ka, and Northern Ba?ka. Novi Sad, the capital of Vojvodina, lies on the border between Ba?ka and Syrmia, on both banks of the river Danube. In some sources, Serbian part of Ba?ka is referred to as Central and Southern Ba?ka (Serbian: ? / Srednja i ju?na Ba?ka; Hungarian: Közép- és Dél-Bácska) or simply Southern Ba?ka (Serbian: / ""Ju?na Ba?ka; Dél-Bácska). The smaller part of the region in Hungary's Bács-Kiskun County is, by the same sources, described as Northern Ba?ka (Hungarian: Észak-Bácska; Serbian: ? / Severna Ba?ka).
The districts of Serbia in Ba?ka are:
Note that municipalities of Sremski Karlovci, Petrovaradin, and Beo?in and southern part of municipality of Ba?ka Palanka that belong to South Ba?ka District are geographically not located in Ba?ka, but in Syrmia, while municipalities of Ada, Senta and Kanji?a which are geographically located in Ba?ka are part of North Banat District.
