The Austrian Empire was a Central European multinational great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous empire after the Russian Empire and the United Kingdom in Europe. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third largest empire in Europe after the Russian Empire and the First French Empire. Proclaimed in response to the First French Empire, it partially overlapped with the Holy Roman Empire until the latter's dissolution in 1806.

The Battle of Batočina was fought on 29–30 August 1689 near the town of Batočina in the Sanjak of Smederevo, between Holy Roman and Ottoman forces during the Great Turkish War (1683–99).

The Habsburg Kings of Hungary were titular rulers (claimants) of Serbia, through the historical vassalage of the Serbian Despotate to the Kingdom of Hungary. The Serbian Despotate was finally conquered by the Ottoman Empire in 1459, while "Little Rascia" in 1521–40. The Vexillum Serviae was one of the flags given to an honorary flag-bearer during the coronation of the king, since 1563. Central Serbia was at times occupied by the Habsburg Monarchy as the "Kingdom of Serbia". The flag included the Triballian boar.

The Great Migrations of the Serbs, also known as the Great Exoduses of the Serbs, refers mainly to two large migrations of Serbs from various territories under the rule of Ottoman Empire to regions under the rule of Habsburg Monarchy in the 17th and the 18th centuries. After the migrations, Serbs became a minority in Kosovo.

Habsburg-occupied Serbia refers to the period between 1686 and 1699 of the Great Turkish War, during which various regions of present-day Serbia were occupied by the Habsburg Monarchy. In those regions, Habsburg authorities have established various forms of provisional military administration, including the newly organized Serbian Militia. By the Treaty of Karlowitz in 1699, some of those regions remained under the permanent Habsburg rule, while others were returned to the Ottoman Empire.

Koča's frontier refers to the Serbian territory established in the Sanjak of Smederevo, Ottoman Empire, during the Austro-Turkish War (1787–1791). The Habsburg-organized Serbian Free Corps, among whom Koča Anđelković was a prominent captain, initially held the central part of the sanjak, between February and September 7, 1788; after the Austrians entered the conflict the territory was expanded and became a Habsburg protectorate under military administration, called Serbia. After the Austrian withdrawal and Treaty of Sistova (1792), the territory was regained by the Ottomans.

The Kingdom of Serbia was a province (crownland) of the Habsburg Monarchy from 1718 to 1739.

Obor-knez was a title borne by elected local native Serbian chiefs (Knyaz) of the nahiyah in the Ottoman Sanjak of Smederevo. The obor-knez was senior chief and responsible for his district's people and was their spokesman (intermediary) in direct relations with the Pasha, though usually through the sipahi, and was in charge of the transfer of taxes levied on the villages. The vojvoda and obor-knez titles were given to people approved by the Pasha. The title was hereditary, being succeeded by one's son. The obor-knez, as a senior, had several knezes under him, who held sub-districts or one village each.

The Serbian Free Corps, known simply as frajkori, was a volunteer militia composed of ethnic Serbs, established by the Habsburg Monarchy, to fight the Ottoman Empire during the Austro-Turkish War (1787–91). The conflict with Turkish forces ultimately proved inconclusive. The rebellion in the Sanjak of Smederevo and militia's operations resulted in the period of Habsburg-occupied Serbia, which took place from 1788 to 1792. Ultimately, the Serbian volunteer corps had the legacy of promoting the creation of future paramilitaries, such as during the First Serbian Uprising.
The Serbian hajduks were brigands and guerrilla fighters (rebels) throughout Ottoman-held Balkans, organized into bands headed by a harambaša, who descended from the mountains and forests and robbed and attacked the Ottomans.

The Serbian national awakening or Serbian Revival refers to a period in the history of the Serbs between the 18th century and the de jure establishment of the Principality of Serbia (1878). It began in Habsburg territory, in Sremski Karlovci. The Serbian renaissance is said to have begun in 17th-century Banat. The Serbian Revival began earlier than the Bulgarian National Revival. The first revolt in the Ottoman Empire to acquire a national character was the Serbian Revolution (1804–1817), which was the culmination of the Serbian renaissance. According to Jelena Milojković-Djurić: "The first literary and learned society among the Slavs was Matica srpska, founded by the leaders of Serbian revival in Pest in 1826." Vojvodina became the cradle of the Serbian renaissance during the 19th century. Vuk Stefanović Karadžić (1787–1864) was the most instrumental in this period.
