The Ottoman dynasty () consisted of the members of the imperial House of Osman (), also known as the Ottomans (). According to Ottoman tradition, the family originated from the Kayı tribe branch of the Oghuz Turks, under Osman I in northwestern Anatolia in the district of Bilecik Söğüt. The Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from 1299 to 1922.
During much of the Empire's 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. During the First (1876–78) and Second Constitutional Eras (1908–20) of the late Empire, a shift to a constitutional monarchy was enacted, with the Grand Vizier taking on a prime ministerial role as head of government and heading an elected General Assembly.
The imperial family was deposed from power and the sultanate was abolished on 1 November 1922 during 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 personae non-gratae, though some have been allowed to return and live as private citizens in Turkey. In its current form, the family is known as the Osmanoğlu family.
History
The Ottoman dynasty operated under several basic premises: that the Sultan governed the empire's entire territory, that every male member of the dynastic family was hypothetically eligible to become Sultan, and that only one person at a time could be the Sultan. Such rules were fairly standard for monarchic empires of the time. The certain processes through which men rose to the Sultanate, however, were very specific to the Ottoman Empire. To go into greater detail about these processes, the history of succession between Sultans can be divided into two eras: the period between the reign of Orhan (1323–1362), the first person to inherit the Ottoman sultanate, and the reign of Ahmed I (1603–1617); and the period following Ahmed I's reign.
The succession process during the first period was dominated by violence and intra-familial conflict, in which the various sons of the deceased Sultan fought until only one remained alive and, thus, inherited the throne. This tradition was known as fratricide in the Ottoman Empire but may have evolved from tanistry, a similar succession procedure that existed in many Turco-Mongolian dynasties predating the Ottomans. Sons of the Sultan were often given provincial territories to govern until the Sultan's death, at which point they would each vie for the throne. Each son had to, according to historian H. Erdem Cipa, "demonstrate that his fortune was superior to the fortunes of his rivals", a demonstration that often took the form of military accomplishment and ruthlessness. This violence was not considered particularly unexpected or unusual. As Cipa has noted, the Ottoman words for "successor" and "conflict" share the same Arabic root, and indeed, all but one of the successions in this roughly 200-year period involved a resolution by combat. Over time, the combat became increasingly prevalent and recognized, especially after a Janissary uprising negated Murad II's attempt to abdicate the throne peacefully to his son, Mehmed II, in 1444. During the eventual reign of Mehmed II (1451–1481), fratricide was legalized as an official practice; during the reign of Bayezid II (1481–1512), fratricide between Bayezid II's sons occurred before Bayezid II himself died; and after the reign of Murad III (1574–1595), his successor Mehmed III executed 19 brothers to claim the throne.
