Quizplus · Accepted Answer

The Seljuk Turks represented the major threat to the Byzantine Empire in the eleventh century. They were a powerful Turkic group that originated from Central Asia and had converted to Islam. Under their leader Tughril Beg, they conquered much of Iran, Iraq, and Syria, and expanded their territory westward, eventually coming into conflict with the Byzantine Empire. Their victory over the Byzantines at the Battle of Manzikert in 1071 was devastating and marked the beginning of a period of decline for the Byzantine Empire.
