OTTOMAN ARCHITECTURE SINAN

MILITARY CAREER
In 1512, Sinan was conscripted into Ottoman service via the devshirme system.He went to Constantinople as a recruit of the Janissary Corps, and converted to Islam.He was too old (over twenty-one years) to be admitted to the imperial Enderun School in the Topkapı Palace but was sent instead to an auxiliary school.Some records claim that he might have served the Grand Vizier Pargalı İbrahim Pasha as a novice of the Ibrahim Pasha School. Possibly, he was given the Islamic name Sinan there. He initially learned carpentry and mathematics but through his intellectual qualities and ambitions, he soon assisted the leading architects and got his training as an architect.

During the next six years, he also trained to be a Janissary officer (acemioğlan). He possibly joined Selim I in his last military campaign, Rhodes according to some sources, but when the Sultan died, this project ended. Two years later he witnessed the conquest of Belgrade. He was present, as a member of the Household Cavalry, in the Battle of Mohács, led by the new sultan Suleiman the Magnificent. He was promoted to captain of Mohács, led by the new sultan Suleiman the Magnificent. He was promoted to captain of the Royal Guard and then given command of the Infantry Cadet Corps. He was later stationed in Austria, where he commanded the 62nd Orta of the Rifle Corps. He became a master of archery, while at the same time, as an architect, learning the weak points of structures when gunning them down. In 1535 he participated in the Baghdad campaign as a commanding officer of the Royal Guard. In 1537 he went on expedition to Corfu and Apulia and finally to Moldavia

During all these campaigns he had proven himself a trained engineer and an able architect. When the Ottoman army captured Cairo, Sinan was promoted to chief architect and was given the privilege of tearing down any buildings in the captured city that were not according to the city plan.[citation needed] During the campaign in the East, he assisted in the building of defences and bridges, such as a bridge across the Danube. He converted churches into mosques. During the Persian campaign in 1535 he built ships for the army and the artillery to cross Lake Van. For this he was given the title Haseki'i, Sergeant-at-Arms in the body guard of the Sultan, a rank equivalent to that of the Janissary Ağa.
When Chelebi Lütfi Pasha became Grand Vizier in 1539, he appointed Sinan, who had previously served under his command, Architect of the Abode of Felicity. This was the start of a remarkable career. It was his task to supervise the constructions and the flow of supplies within the Ottoman empire. He was also responsible for the design and construction of public works, such as roads, waterworks and bridges. Through the years he transformed his office into that of Architect of the Empire, an elaborate government department, with greater powers than his supervising minister. He became the head of a whole Corps of Court Architects, training a team of assistants, deputies and pupils.
