The Kingdom of Serbia (Serbian: Краљевина Србија, romanized: Kraljevina Srbija, German: Königreich Serbien, Latin: Regnum Serviae) was a province (crownland) of the Habsburg monarchy from 1718 to 1739.

It was formed from the territories to the south of the rivers Sava and Danube, corresponding to the Sanjak of Smederevo (or "Belgrade Pashalik"), conquered by the Habsburgs from the Ottoman Empire in 1717.

The Treaty of Karlowitz in 1699 recognized Ottoman authority over most of present-day Serbia, while the region of Bačka and the western part of Syrmia were assigned to the Habsburgs.

[4] Following the Treaty of Passarowitz (1718), the Habsburgs established the Kingdom of Serbia and appointed the first command cadre of the Serbian National Militia, composed out of two obor-kapetans, ten kapetans, two lieutenants and one major.

[7][8] Although the Habsburg administration over this part of present-day Serbia was short-lived, the consciousness about separate political entity was left behind by the Habsburgs, thus local inhabitants never again fully accepted Ottoman administration, which led to Koča's frontier rebellion in 1788 and to the First Serbian Uprising in 1804, which ended direct Ottoman rule over this part of present-day Serbia.
