Turkish Military Academy in the context of Ministry of National Defense (Turkey)

The Ottoman Army was the military of the Ottoman Empire after the country was reorganized along modern western European lines during the Tanzimat modernization period. In 1826, Sultan Mahmud II abolished the Janissary Corps, which had existed for centuries but was unable to adapt to modern military tactics and frequently rebelled. In its place, he established the Asakir-i Mansure-i Muhammediye (Victorious Soldiers of Prophet Muhammad) army that same year. The Sultan continued his reform efforts by establishing modern institutions to support the army. In 1826, he established the Seraskerlik , equivalent to a modern Ministry of Defense. In 1827, the first military medical school,Imperial School of Medicine, was opened to train doctors and surgeons for the army. In 1834, Harbiye Military School was opened with the support of French military instructors to train officers for the army.

On June 14, 1843, Sultan Abdülmecid changed the army's name to Asâkir-i Nizâmiye-i Şâhâne (Royal Regular Soldiers). From this date onward, the army began to be known simply as the Nizami Ordu (Regular Army). In 1845, he established Kuleli Military High School, the first modern military high school, in the capital Istanbul. In 1848, the first military academy, Erkan-ı Harbiye Military Academy, was opened to train army staff officers and high-ranking officers, or pashas. The Crimean War was the first war effort in which the modern army took part in, proving itself as a decent force. The last reorganization occurred during the Second Constitutional Era.

The Mansure Army (Ottoman Turkish: عساكر منصورهٔ محمديه, romanized: Asâkir-i Mansûre-i Muhammediye, "The Victorious Soldiers of Muhammad") was initially an ocak (military unit) of the Ottoman army but later became a new army force. It was established by Mahmud II, who also disbanded the Janissary Corps. The army's name was changed to the Asâkir-i Nizâmiye-i Şâhâne (Royal Regular Soldiers) in 1843 and the army continued its existence until 1918 and joined the Grand National Assembly government stationed in Ankara during the War of Independence. With the proclamation of the republic, the army was transformed into the Turkish Land Forces.

After The Auspicious Incident and the disbandment of the Janissary Corps, Mahmud II established a new military ocak and Agha Hussein Pasha was appointed to the command of the corps. Koca Hüsrev Mehmed Pasha served as their serasker. The foundations of the modern Turkish Army were laid during the reign of Sultan Mahmud II. After the Janissary Corps, which was outdated and could not adapt to the times, was abolished with the Auspicious Incident (June 15, 1826), Sultan Mahmud II ordered the establishment of Asakir-i Mansure-i Muhammediye (Victorious Soldiers of Muhammad). By embarking on a rapid modernization effort that took the military and technical developments in Europe as an example, the new army decree was approved by Sultan Mahmud II on July 7, 1826, and the Asâkir-i Mansûre-i Muhammediyye Army, the modern army of the empire, was established. After this date, Sultan Mahmud II accelerated his reform efforts and started to establish schools and institutions to support the new army. The Seraskerlik institution, a high military command, was established by Mahmud II in 1826 to fulfill the duties of the commander-in-chief, and on 14 March 1827, Imperial Military School of Medicine, which is the basis of Turkey's first medical faculty and modern military hospital Gülhane Training and Research Hospital, was established to meet the army's need for physicians and surgeons. Harbiye Military School was later established in 1834 as a modern officer school modeled on the French and Prussian armies, taught by European instructors.
