context_page_description: The Ottoman Empire was a state that controlled much of Southeastern Europe, Western Asia, and Northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt by the Turkoman tribal leader Osman I. Although initially the dynasty was of Turkic origin, it was Persianised in terms of language, culture, literature and habits. After 1354, the Ottomans crossed into Europe and with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.
  During the 16th and 17th centuries, at the height of its power, under the reign of Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire controlling most of Southeastern Europe, Central Europe, Western Asia, parts of Eastern Europe, the Caucasus, Northern Africa, and the Horn of Africa. At the beginning of the 17th century, the empire contained 32 provinces and numerous vassal states.
context_section_description: The first military unit of the Ottoman State was an army that was organized by Osman I from the tribesmen inhabiting the hills of western Anatolia in the late 13th century. The military system became an intricate organization with the advance of the Empire. The Ottoman military was a complex system of recruiting and fief-holding. The main corps of the Ottoman Army included Janissary, Sipahi, Akıncı and Mehterân. The Ottoman army was once among the most advanced fighting forces in the world, being one of the first to use muskets and cannons. The Ottoman Turks began using falconets, which were short but wide cannons, during the Siege of Constantinople. The Ottoman cavalry depended on high speed and mobility rather than heavy armour, using bows and short swords on fast Turkoman and Arabian horses (progenitors of the Thoroughbred racing horse), and often applied tactics similar to those of the Mongol Empire, such as pretending to retreat while surrounding the enemy forces inside a crescent-shaped formation and then making the real attack. The Ottoman army continued to be an effective fighting force throughout the seventeenth and early eighteenth centuries, falling behind the empire's European rivals only during a long period of peace from 1740–1768.
  The modernization of the Ottoman Empire in the 19th century started with the military. In 1826 Sultan Mahmud II abolished the Janissary corps and established the modern Ottoman army. He named them as the Nizam-ı Cedid (New Order). The Ottoman army was also the first institution to hire foreign experts and send its officers for training in western European countries. Consequently, the Young Turks movement began when these relatively young and newly trained men returned with their education.
  The Ottoman Navy vastly contributed to the expansion of the Empire's territories on the European continent. It initiated the conquest of North Africa, with the addition of Algeria and Egypt to the Ottoman Empire in 1517. Starting with the loss of Greece in 1821 and Algeria in 1830, Ottoman naval power and control over the Empire's distant overseas territories began to decline. Sultan Abdülaziz (reigned 1861–1876) attempted to reestablish a strong Ottoman navy, building the largest fleet after those of Britain and France. The shipyard at Barrow, England, built its first submarine in 1886 for the Ottoman Empire.
  However, the collapsing Ottoman economy could not sustain the fleet's strength for long. Sultan Abdülhamid II distrusted the admirals who sided with the reformist Midhat Pasha and claimed that the large and expensive fleet was of no use against the Russians during the Russo-Turkish War. He locked most of the fleet inside the Golden Horn, where the ships decayed for the next 30 years. Following the Young Turk Revolution in 1908, the Committee of Union and Progress sought to develop a strong Ottoman naval force. The Ottoman Navy Foundation was established in 1910 to buy new ships through public donations.
  The establishment of Ottoman military aviation dates back to between June 1909 and July 1911. The Ottoman Empire started preparing its first pilots and planes, and with the founding of the Aviation School (Tayyare Mektebi) in Yeşilköy on 3 July 1912, the Empire began to tutor its own flight officers. The founding of the Aviation School quickened advancement in the military aviation program, increased the number of enlisted persons within it, and gave the new pilots an active role in the Ottoman Army and Navy. In May 1913, the world's first specialized Reconnaissance Training Program was started by the Aviation School, and the first separate reconnaissance division was established. In June 1914 a new military academy, the Naval Aviation School (Bahriye Tayyare Mektebi) was founded. With the outbreak of World War I, the modernization process stopped abruptly. The Ottoman aviation squadrons fought on many fronts during World War I, from Galicia in the west to the Caucasus in the east and Yemen in the south.
