Infantry Janissaries The
Janissaries were elite infantry units created by Sultan
Murad I. They formed the Ottoman Sultan's household troops and bodyguards and became a famed force in 1383. They were units that formed the infantry contingents of the Ottoman Sultan's household troops, recruited through the process of
devshirme. For all practical purposes, Janissaries belonged to the Sultan, carrying the title
kapıkulu (Subject of the gate) indicating their collective bond with the Sultan. Janissaries were taught to consider the corps as their home and family, and the Sultan as their
de facto father. The janissary corps was significant in a number of ways. The janissaries wore
uniforms, were paid in cash as regular soldiers, and marched to distinctive music, by the
mehter. The Janissaries were a formidable military unit in the early centuries, but as Western Europe modernized its military organization and technology, the Janissaries became a reactionary force that resisted all change. Steadily the Ottoman military power became outdated, but when the Janissaries felt their privileges were being threatened, or outsiders wanted to modernize them, or they might be superseded by their cavalry rivals, they rose in rebellion.
Yaya The history of
Yaya goes to the early Ottoman military forces consisted of irregular nomadic cavalry and volunteer light infantry. These units were efficient against local Byzantine feudal lords but were unable to capture fortified castles by direct assault. Established by Sultan Orhan during Alaeddin Pasha's reorganization the military in the mid 1320s. Yaya and Musellem over time lost their original martial qualities.
Cavalry The
Six Divisions of Cavalry, also known as the Kapıkulu Süvarileri ("Household Cavalry of Gate Slaves"), was a corps of elite cavalry soldiers in the army of the Ottoman Empire. There were not really six, but four, divisions in the corps. Two of the six were sub-divisions.
Silahdars The
Silahdars (From Persian, translated roughly as "men at arms") were a bodyguard division for the Sultan, under the command of the
Silahdar Agha. Silahdars were chosen from the best warriors. Any Ottoman soldier who committed a significant deed on the battlefield could be promoted to the Silahdar division, although normally members of other mounted units, like Timarli Sipahis or one of the other less prestigious of the four divisions of Kapikulu Sipahis, were promoted this way. Infantry soldiers had to enlist as serdengecti (literally means giver of his head) and survive suicide missions to join the Silahdar division. If a janissary ever became a silahdar, other members of the division with cavalry backgrounds despised him and former comrade janissaries considered him a traitor, but because the position and wealth of a silahdar was so attractive, janissaries and other soldiers still enlisted for suicide missions.
Sipahi (Persian: "soldier")
Sipahi refers to all freeborn heavy cavalry other than akıncıs and tribal horsemen in the Ottoman army. The word was used almost synonymously with cavalry.
Akıncı Akıncı were irregular light cavalry, scout divisions and advance troops. They were one of the first divisions to face the opposing military and were known for their prowess in battle. Unpaid they lived and operated as raiders on the frontiers of the Ottoman Empire, subsisting totally on plunder. The Akıncıs continued to serve until 1595 when after a major rout in Wallachia they were dissolved by Grand Vezir Koca Sinan Paşa.
Artillery In this section, the artillery corps (
Topçu Ocağı: literally the hearth of artillerymen), the armorer corps (
Cebeci Ocağı: literally the hearth of armourers), the artillery wagoners (
Top Arabacıları Ocağı: literally the hearth of artillery wagoners), the bombardiers (
Humbaracı Ocağı: literally the hearth of bombardiers), the miners (
Lağımcı Ocağı: literally the hearth of miners).
Topçu The Topçu Ocağı (artillery corps) was responsible for the use of artillery pieces. It is not clear when artillery was first used by the Ottoman Army. Although some argue that the Ottomans used cannons in the Battles of
Kosovo (1389) and
Nicopolis (1396), it is certain that artillery was routinely used by the 1420s. However the other argument states that field guns entered service shortly after the
Battle of Varna (1444) and more certainly used in the
Second Battle of Kosovo (1448). Specialist 'topçu' or artillery units were formed mainly of Christians; units such as
tayfa-i efreciye. In the
siege of Baghdad where the Ottomans retook the city from the Persians (1638), gunners of European descent served on the lines. Their commander was called
Cebecibaşı. The unit was small and selected, numbering no more than 625 men in 1574. The Cebeci unit was in charge of maintenance and keeping the weaponry. They were also responsible in transporting weapons to where they were needed.
Support units The Ottoman armies were distinguished from their contemporaries in the West not by numerical predominance of its military forces but by the thoroughness of the administrative backup and general support that maintained them in the field. The auxiliary support system also set the Classical Army apart from their contemporaries. The janissaries waged war as one part of a well-organized military machine. The Ottoman army had a corps to prepare the road, a corps to pitch the tents ahead, a corps to bake the bread. The
cebeci corps carried and distributed weapons and ammunition. The janissary corps had its own internal medical auxiliaries: Muslim and Jewish surgeons who would travel with the corps during campaigns and had organized methods of moving the wounded and the sick to traveling hospitals behind the lines.
Military band Ottoman military bands are thought to be the oldest variety of military marching band in the world. Though they are often known by the Persian-derived word mehter in the West, that word, properly speaking, refers only to a single musician in the band.
Paramilitary units Ottomans had forces organized as a group supplementing but not directly incorporated in a regular military.
Derbendjis Dervendjis were the most important and largest Ottoman military auxiliary constabulary units usually responsible for guarding important roads, bridges, fords or mountain passes. Usually, the population of an entire village near some important pass would be assigned with derbendci status in exchange for tax exemptions. By rehabilitating the Derbendcis, the Ottomans released conventional military units from routine internal duties, such as guarding and repairing roads, bridges. ==Organization ==
