Osman III lived most of his life as a prisoner in the palace, and as a consequence, he had some behavioural peculiarities when he took the throne. Unlike previous sultans, he hated music, and banished all musicians from the palace. According to
Baron de Tott, Osman III was an angry and a modest type of ruler. Osman III's initial action in governance was to select officials to collaborate with. Throughout his reign, the alterations he implemented in high-level governmental positions, particularly that of the Grand Vizier, can be seen as efforts to diminish the overwhelming influence of the charitable authority prevalent during the previous sultan's era. In the second year of his reign, Osman lost his mother Şehsuvar Sultan, afterward, the oldest prince Mehmed, died of illness on 22 December 1756. According to various sources, the funeral of the prince, controlled by the
grand vizier and the
sheikh al-Islam. It was attended by 5,000 people and contemporary sources mentioned that the prince was poisoned and killed on the initiative of
Köse Mustafa Pasha. The sultan was notified of provisions sent to oppose banditry in
Anatolia and
Rumelia. Measures were taken against the tribes of
Bozulus and Cihanbeyli, the Armenians (due to the turmoil in Iran), the bandits around
Erzurum and
Sivas, and the famous leader
Karaosmanoğlu Hacı Mustafa Ağa. The latter was captured and executed, and his head was brought to Istanbul on 5 December 1755.
Architecture Osman is famous for building the
Nuruosmaniye Mosque, whose construction started during the reign of Mahmud I. Nuruosmaniye Complex, also known as Osmaniye for a while, consisted of three schools, madrasahs, a factory, a library, a mausoleum, a temporary room, a mesh house, a fountain, an inn, and shops. Osman built a new neighborhood in 1755-56 where Üsküdar Palace and Garden was located, along with houses and shops. He also built the Ihsaniye Mosque and its masajid ( plural of masjid ), both of which stand today as İhsaniye. Osman III built a fountain in his name in 1755–56; it was destroyed 122 years after its construction. ==Death==
