The tribe known as the Ottomans arose from one of the smaller emirates established in northwestern Anatolia after 1071. This led them into conflict with the Seljuk Turks, and to pacify the nomadic tribes, the Seljuks directed them to the eastern domain of the Byzantine Empire, Anatolia. However, many other Turkish groups remained nomadic and, pursuing the gazi tradition, sought to conquer land for Islam and to acquire war booty for themselves.

The Migration Period, also called the Barbarian Invasions (and in German: Völkerwanderung 'migration of peoples'), was a period of human migration that occurred during roughly 300–700 A.D.

Their descendants, or successors with similar names, are recorded by neighboring populations to the south, east, and west as having occupied parts of Eastern Europe and Central Asia roughly from the 4th century to the 6th century. They formed a unified empire under Attila the Hun, who died in 453 their empire broke up the next year. It is thought by many, that the Huns may have stimulated the "Great Migration" a contributing factor in the collapse of the western Roman Empire.
