Bačka in the context of "Novi Sad"

Banat, Bačka, and Baranya (Serbo-Croatian: Banat, Bačka i Baranja / Банат, Бачка и Барања) was a province of the Kingdom of Serbia and the Kingdom of Serbs, Croats, and Slovenes between November 1918 and 1922. It included the geographical regions of Banat, Bačka, and Baranya and its administrative center was Novi Sad. They were later separated from the country to become SAP Vojvodina in 1945 with the creation of Federal Yugoslavia; smaller parts of Baranya were incorporated into Croatia or ceded to Kingdom of Hungary, while a portion of Banat was ceded to Kingdom of Romania.

Vojvodina (Serbian: Војводина, IPA: [vǒjvodina], VOY-və-DEE-nə), officially the Autonomous Province of Vojvodina (Serbian: Аутономна Покрајина Војводина, romanized: Autonomna Pokrajina Vojvodina), is an autonomous province in northern Serbia. It encompasses the historical and geographical regions of Bačka, Banat, Syrmia, and northernmost part of Mačva, lying to the north of the national capital Belgrade and the Sava and Danube rivers. Vojvodina has 1.7 million inhabitants, about a quarter of the country's population, and its administrative centre, Novi Sad, is the second largest city in Serbia.

The invasion of Yugoslavia, also known as the April War or Operation 25, was a German-led attack on the Kingdom of Yugoslavia by the Axis powers which began on 6 April 1941 during World War II. The order for the invasion was put forward in "Führer Directive No. 25", which Adolf Hitler issued on 27 March 1941, following a Yugoslav coup d'état that overthrew the pro-Axis government.

The invasion commenced with an overwhelming air attack on Belgrade and facilities of the Royal Yugoslav Air Force (VVKJ) by the Luftwaffe (German Air Force) and attacks by German land forces from southwestern Bulgaria. These attacks were followed by German thrusts from Romania, Hungary and the Ostmark (modern-day Austria, then part of Germany). Italian forces were limited to air and artillery attacks until 11 April, when the Italian Army attacked towards Ljubljana (in modern-day Slovenia) and through Istria and Lika and down the Dalmatian coast. On the same day, Hungarian forces entered Yugoslav Bačka and Baranya, but like the Italians they faced practically light resistance. Italians moved into Dalmatia also from Italian-controlled Albania, after repelling an initial Yugoslav attack there.

The South Bačka District (Serbian: Јужнобачки округ, romanized: Južnobački okrug, pronounced [jûʒnobâːtʃkiː ôkruːɡ]) is one of administrative districts of Serbia. It lies in the southern part of Bačka and northern part of Syrmia. According to the 2022 census, the South Bačka District has a population of 607,178 inhabitants. The administrative center of the district is the city of Novi Sad, which is also the administrative center and the largest city of the Vojvodina.

The Serbian Vojvodina (Serbian: Српска Војводина, romanized: Srpska Vojvodina) was a short-lived self-proclaimed autonomous province within the Austrian Empire during the Revolutions of 1848, which existed until 1849 when it was transformed into the new (official) Austrian province named Voivodeship of Serbia and Temes Banat. It was created and led by political leaders of Serbs in regions of Syrmia, Banat, Bačka and Baranja. The Serbian Vojvodina gave its name to the present Vojvodina autonomous region in Serbia.

The border between Croatia and Serbia in the area of the Danube is disputed, an important part of their broader diplomatic relations. While Serbia claims that the thalweg of the Danube valley and the centreline of the river represent the international border between the two countries, Croatia disagrees, claiming that the international border lies along the boundaries of the cadastral municipalities located along the river—departing from the course at several points along a 140-kilometre (87 mi) section. The cadastre-based boundary reflects the course of the Danube which existed in the 19th century, before anti-meandering and hydrotechnical engineering works altered its course. The area size of the territory in dispute is reported variously, up to 140 km (54 square miles).

The dispute first arose in 1947, but was left unresolved during the existence of the Socialist Federal Republic of Yugoslavia. After the breakup of Yugoslavia, the dispute would become a contentious issue. Particular prominence was given to the dispute at the time of Croatia's accession to the European Union. The dispute remains unresolved, and the line of control mostly corresponds to Serbia's claim.

The North Bačka District (Serbian: Севернобачки округ, romanized: Severnobački okrug, pronounced [sêʋeːrnobâːtʃkiː ôkruːɡ]) is one of administrative districts of Serbia. It lies in the geographical region of Bačka. According to the 2022 census, the North Bačka District has a population of 160,163 inhabitants. The administrative center of the district is the city of Subotica.
