Pressured out of their homes in the Asian steppes by the Mongols, the Turkish nomadic tribes<span> converted to </span>Islam<span> during the eighth and ninth centuries. By the tenth century, one of the </span>Turkish tribes<span>, the </span>Seljuk<span>, had become a significant power in the </span>Islamic<span> world and had adopted a settled life that included </span>Islamic<span> orthodoxy, a central administration, and </span>taxation<span>. However, many other </span>Turkish groups<span> remained </span>nomadic<span> and, pursuing the </span>gazi<span> tradition, sought to conquer land for </span>Islam<span> and to acquire war booty for themselves. This led them into conflict with the </span>Seljuk<span> Turks, and to pacify the </span>nomadic<span> tribes, the </span>Seljuks<span> directed them to the eastern domain of the </span>Byzantine Empire<span>, </span>Anatolia<span>. The </span>tribe<span> known as the Ottomans arose from one of the smaller </span>emirates<span> established in northwestern </span>Anatolia<span> after 1071. The </span>dynasty<span> was named for </span>Osman<span> (1259-1326), who began to expand his kingdom into the </span>Byzantine Empire<span> in </span>Asia Minor<span>, moving his capital to </span>Bursa<span> in 1326.</span>
