The Sanjak of Prizren (Turkish: "Prizren Sancağı" , Albanian: "Sanxhaku i Prizrenit" , Serbian: Призренски санџак ) was one of the sanjaks in the Ottoman Empire with Prizren as its administrative centre.
 It was founded immediately after Ottoman Empire captured Prizren from Serbian Despotate in 1455.
 It was one of the sanjaks established on the territory which Ottoman Empire conquered from Serbian Despotate.
 The rest of the territory of Serbian Despotate was conquered after the fall of Smederevo in 1459, and divided into following sanjaks: Sanjak of Vučitrn, Sanjak of Kruševac and Sanjak of Smederevo.
 At the beginning of the First Balkan War in 1912, the territory of Sanjak of Prizren was occupied by the armies of Kingdom of Serbia and Kingdom of Montenegro.
 Based on Treaty of London signed on May 30, 1913, the territory of Sanjak of Prizren was divided between Serbia and Montenegro.
The Treaty of Niš was a peace treaty signed on 3 October 1739 in Niš (East Serbia), by the Ottoman Empire and Russian Empire, to end the Russo-Turkish War of 1735-1739.
 The Russians gave up their claim to Crimea and Moldavia but were allowed to build a port at Azov, though without fortifications and without the right to have a fleet in the Black Sea.
 The war was the result of a Russian effort to gain Azov and Crimea as a first step towards dominating the Black Sea.
 The Habsburg Monarchy entered the war in 1737 on the Russian side, but was forced to make peace with Ottomans at the separate Treaty of Belgrade, surrendering Northern Serbia, Northern Bosnia and Oltenia, and allowing the Ottomans to resist the Russian push toward Constantinople.
 In return, the Sultan acknowledged the Habsburg Emperor as the official protector of all Ottoman Christian subjects ("see Ottoman millet"), a position also claimed by Russia.
 The Austrian peace treaty compelled Russia to accept peace at Niš, ending the war with a partial Russian victory.
The Sanjak of Pojega (Turkish: "Pojega Sancağı" ; Croatian: "Požeški sandžak" ) was an administrative unit of the Ottoman Empire formed around 1538.
 It existed until the Treaty of Karlowitz (1699), when the region was transferred to the Habsburg Monarchy.
 It was located in present-day eastern Croatia, in Slavonia region.
 The capital of the sanjak was Pojega (Croatian: Požega).
Sanjak of Syrmia (Turkish: "Sirem sancağı" , Serbian: Sremski sandžak/Сремски санџак , Croatian: "Srijemski sandžak" ) was an administrative unit of the Ottoman Empire formed in 1541.
 It was located in the Syrmia region and was part of the Budin Province.
 Administrative center of the Sanjak of Syrmia was from 1542 Uyluk (Croatian: Ilok) and in the second half of the 17th century it was Dimitrofça (Serbian: Dmitrovica, today Sremska Mitrovica).
 Most of the sanjak was ceded to Austria according to Treaty of Karlovitz in 1699.
 Remainder of the territory of sanjak was transferred to Sanjak of Semendire and was later also ceded to Austria according to Treaty of Passarowitz in 1718.
The Habsburg Monarchy (German: "Habsburgermonarchie" ) or Empire, is an unofficial appellation among historians for the countries and provinces that were ruled by the between 1521 and 1780 and then by the successor branch of Habsburg-Lorraine until 1918.
 The Monarchy was a composite state composed of territories within and outside the Holy Roman Empire, united only in the person of the monarch.
 The dynastic capital was Vienna, except from 1583 to 1611, when it was moved to Prague.
 From 1804 to 1867 the Habsburg Monarchy was formally unified as the Austrian Empire, and from 1867 to 1918 as the Austro-Hungarian Empire.
The Treaty of Karlowitz was signed on 26 January 1699 in Sremski Karlovci, in modern-day Serbia, concluding the Austro-Ottoman War of 1683–97 in which the Ottoman side had been defeated at the Battle of Zenta.
 It marks the end of Ottoman control in much of Central Europe, with their first major territorial losses after centuries of expansion, and established the Habsburg Monarchy as the dominant power in Central and southeast Europe.
Since the days of Rudolph of Habsburg and the 1283 Treaty of Rheinfelden, the combination of red-white-red was widely considered to be the Austrian (later also Inner Austrian) colours used by the ruling Habsburg dynasty.
 However, the "national flag" (in a modern sense) of the Austrian Habsburg Monarchy, like the later Austrian Empire and the Cisleithanian part of Austria-Hungary until 1918, was black-yellow.
 These were the family colours of the Imperial House of Habsburg, and were themselves in part derived from the banner of the Holy Roman Empire.
The Treaty of Baden was the treaty that ended formal hostilities between France and the Holy Roman Empire, who had been at war since the start of the War of the Spanish Succession.
 It was signed on 7 September 1714 in Baden, Switzerland, and complemented the treaties of Utrecht and of Rastatt.
 By the Treaty of Rastatt Emperor Charles VI accepted the Utrecht treaty on behalf of the Habsburg Monarchy.
 In the Baden treaty, the terms of peace between France and the Holy Roman Empire — formally incomplete — were agreed, and thereby the last of the many conflicts within the War of the Spanish Succession was ended.
 The details of the Treaty of Baden and the peace conference held in this town are recalled by the town's banneret and eye-witness Caspar Joseph Dorer (1673-1754) in his "Diarium".
The Treaty of Belgrade, known as the Belgrade peace was the peace treaty signed on September 18, 1739 in Belgrade, Habsburg Kingdom of Serbia (today Serbia), by the Ottoman Empire on one side and the Habsburg Monarchy on the other, that ended the Austro–Turkish War (1737–39).
Karlo Pavao Gvozdanović (German: "Karl Paul von Quosdanovich" , in some sources also "Quasdanovich" or "Guosdanovich"; Brezovac Žumberački near Samobor, Kingdom of Croatia within Habsburg Monarchy, 1763 – Pančevo, Banat Military Frontier, Habsburg Monarchy, 5 February 1817) was a Croatian nobleman and general in the Habsburg Monarchy imperial army service.
 He achieved the rank of major general and was awarded the Knight's Cross of the Military Order of Maria Theresa in 1801 and the Commander's Cross of the same order of merit in 1814.
