Ottoman army in the context of "Binbashi"

The siege of Belgrade (Hungarian: Nándorfehérvár ostroma) in 1521 is an event that followed as a result of the third major Ottoman attack on this Hungarian stronghold in the Ottoman–Hungarian wars at the time of the greatest expansion of the Ottoman Empire to the west. Ottoman Sultan Suleiman the Magnificent launched his army in mid-May 1521. The Hungarian state was almost in disarray and unable to effectively counter the Ottoman army.

A bashi-bazouk (Ottoman Turkish: باشی بوزوق başıbozuk, IPA: [baʃɯboˈzuk], lit. 'one whose head is turned, damaged head, crazy-head', roughly "leaderless" or "disorderly") was an irregular soldier of the Ottoman army, raised in times of war. The army primarily enlisted Albanians and sometimes Circassians as bashi-bazouks, but recruits came from all ethnic groups of the Ottoman Empire, including slaves from Europe or Africa. Bashi-bazouks had a reputation for being undisciplined and brutal, notorious for looting and preying on civilians as a result of a lack of regulation and of the expectation that they would support themselves off the land.

Timariot (or tımar holder; tımarlı in Turkish) was the name given to a Sipahi cavalryman in the Ottoman army. In return for service, each timariot received a parcel of revenue called a timar, a fief, which were usually recently conquered plots of agricultural land in the countryside. Far less commonly, the sultan would grant a civil servant or member of the imperial family a timar. Also non-military timar holders were obliged to supply the imperial army with soldiers and provisions.

The timariots provided the backbone of the Ottoman cavalry force and the army as a whole. They were obligated to fight as cavalrymen in the Ottoman military when called upon. The timariots had to assemble with the army when at war, and had to take care of the land entrusted to him in times of peace. When at war, the timariot had to bring his own equipment and in addition a number of armed retainers (cebelu). The timariot was granted feudatory with the obligation to go mounted to war and to supply soldiers and sailors in numbers proportionate to the revenue of the appanage. The timariot owed personal service for his sword in time of war and for a certain sum of money owed a number of soldiers as a substitute (cebelu). The (cebelu) was bound to live on the timariot’s estate and look after the land. When summoned for campaign the timariot and his cebelu had to present themselves with a cuirass. When a timariot failed to obey the summon he was deprived of his timar for one or two years. Timariots were expected to bring cebelus or men-at-arms as well as their own equipment on campaign, the number of cebelu being determined by revenue. The number of the timariots in the sultan's army fluctuated between 50,000 and 90,000 men. Timariots were themselves organized by sanjak-beys who ruled over groups of timars. The sanjak-beys were subordinate to the beylerbeyi and then the sultan himself. This semi-feudal arrangement allowed for the Ottomans to organize large armies at once, thus making an imperial army from what was still essentially a medieval economy. This system of using agricultural revenue to pay troops was influenced by a similar Byzantine practice and other Near Eastern states prior to the Ottoman Empire.

The Muslim uprisings in Kars and Sharur–Nakhichevan were a series of insurgencies by local Muslims against the administration of the First Republic of Armenia, beginning on 1 July 1919 and ending 28 July 1920. The areas of uprising were persuaded into insurrection by the sedition of Turkish and Azerbaijani agents who were trying to destabilise Armenia in order to form a pan-Turkic corridor between their nations.

Following the withdrawal of the Ottoman army from the South Caucasus, local Muslims in the formerly occupied areas were armed and assisted in establishing political states with the aim of resisting reincorporation into Armenia. In the spring of 1919, the British command in the Caucasus assisted Armenia in defeating these statelets; however, some months later due to the efforts of Turkish and Azerbaijani emissaries, Armenian administration collapsed and the region fell under local control again until the Armenian counteroffensive in the summer of 1920. The Armenian campaign to reabsorb the Nakhichevan region was halted by the forces of Soviet Russia who had invaded Azerbaijan earlier in the year. The Kars region was briefly reincorporated into Armenian governance until it was conquered by Turkish forces by the end of the Turkish–Armenian war in December 1920.

The Battle of Kars (19 August 1745) was the last major engagement of the Ottoman–Persian War. The battle resulted in the complete and utter destruction of the Ottoman army. It was also the last of the great military triumphs of Nader Shah. The battle was in fact fought over a period of ten days in which the first day saw the Ottomans routed from the field, followed by a series of subsequent blockades and pursuits until the final destruction of the Ottoman army. The severity of the defeat, in conjunction with another defeat near Mosul, ended any hopes of Ottoman victory and forced them to enter into negotiations with a significantly weaker position than they would otherwise have occupied.
