The Ottoman dynasty was made up of the members of the imperial House of Osman (Ottoman Turkish: خاندان آل عثمان‎). The Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from c. 1299 to 1922. During much of its history, the sultan was the absolute regent, head of state, and head of government, though much of the power often shifted to other officials such as the Grand Vizier. The imperial family was deposed from power and the sultanate was abolished on 1 November 1922 after the Turkish War of Independence. The Republic of Turkey was declared the following year. The living members of the dynasty were initially sent into exile as persona non gratae, though some have been allowed to return and live as private citizens in Turkey.
