In the 13th century a nomadic Turkish tribesman named Ertogrul established control over large parts of northwest Anatolia. The Ottoman Empire took its name from his son Osman (r. 1280–1324); Ottoman was an Italian corruption of Osmanli.
As the Seljuk dynasty and other Turkish dynasties, the Ottoman Empire relied on ghazi warriors as the foundation of its military power. The Ghazi warriors were an egalitarian society in which leadership was earned through bravery and feats in battle.
They practiced a code of conduct (futuwwa) analogous to the code of chivalry among western medieval knights. Converts to Sunni Islam, the Ottomans viewed themselves as protectors of Islam.
Osman married the daughter of a Sufi shaykh who was the master of one of the numerous Sufiorders that had been established in Asia Minor. Sufi shaykhs often became the spiritual leaders in Ottoman society.
Like all early Ottoman leaders Osman and his son Orhan (r. 1324–c. 1359) were able military leaders who personally led their troops into battle. Both expanded Ottoman territories and, with the conquest of Gallipoli, Orhan extended Ottoman lands into Europe.
Murad I (r. 1360–89) took the title of sultan and continued Ottoman expansion into the Balkans and Anatolia, taking Adrianople and Ankara. Ottoman victories further diminished the territories under the Byzantine Empire. The Ottoman victory at the Battle of Kosovo in 1389 was a major defeat for the Serbians and began a long period of Ottoman domination over most of the Balkans.
The first 10 Ottoman sultans were men of strong personalities with remarkable abilities. The position of sultan was the only role reserved for the heirs of the house of Osman; otherwise, the Ottoman Empire fostered remarkable upward mobility for its conquered peoples, who could, and often did, rise to the highest military, political, and economic positions within the empire.

Following Muslim precepts the Ottomans were also tolerant of religious minorities and often intermarried with the different religious and ethnic groups within the empire. However a Turkish-speaking elite dominated the ruling class.
In Europe the early Ottomans ruled from Edirne (Adrianople), while Bursa served as the capital of the empire. The relative stability of Ottoman rule attracted scholars and merchants to Bursa. Merchants and skilled craftsmen formed guilds of ahki or cooperatives that contributed to the economic prosperity of the empire.
The control of major trade routes also financially benefited the Ottomans. Charitable foundations (awqaf) provided extensive social services. An Islamic legal system with trained qadis (judges) provided an overall judicial framework for the empire.
Bayezid I (r. 1389–1402) became sultan after the death of his father, Murad I, at the Battle of Kosovo. To ensure his succession Bayezid had his brother killed; subsequent Ottoman sultans often sanctioned fratricide or the imprisonment of family members to prevent rebellions or divisions over succession. Although Bayezid won a number of battles in the Balkans and Anatolia, he also adopted a number of Byzantine or Balkan social customs.
Under his sultanate a lavish royal court emerged. Ottoman sultans frequently married non-Turkish women. The harem, composed of the sultan’s mother, wives, former wives, and concubines, grew in size and importance. The mothers and wives of the sultans became powers in their own right and frequently intrigued to secure the succession of their favorite sons to the sultanate.
Timurlane (Tamerlane) stopped Ottoman territorial expansion. At the Battle of Ankara in 1402 he captured Bayezid and subsequently had him killed. Timurlane dismembered Ottoman territory, dividing it among separate rulers.

However, following a struggle with his brothers, Mehmed I (r. 1413–21) presided over a remarkable revival of the empire, which emerged stronger and more powerful than previously. Murad II (r. 1421–44; 1446–51) resumed the expansion and control over the Balkans and moved into Hungary. Although he besieged Constantinople he failed to take the city.
The victory in 1444 at the Battle of Varna marked the consolidation of Ottoman rule over the Balkans. Within a decade the Ottomans would achieve a final victory over the failing Byzantine Empire.
