The so-called "Ottomans" came into Western consciousness when they relocated from their native Central Asia to the Seljuk Sultanate of Rum in Anatolia in the 13th century. In Western Anatolia, the Ottoman Turks established a beylik with Söüt as its capital under Ertugrul's rule. The chief of the nomadic Kay tribe, Ertugrul, established the first principality during the final years of the Seljuk empire. His son Osman expanded the principality, and in recognition of him, Europeans gave the people and the political system the name "Ottomans" ("Ottoman" being a corruption of "Osman"). Osman's son Orhan turned the expanding area into an empire in 1362 with the conquest of Nicaea (modern-day Znik) and the traversal of the Dardanelles.
