Alp Arslan, born Muhammad bin Dawud Chaghri, was the second sultan of the Seljuk Empire and great-grandson of Seljuk, the eponymous founder of the dynasty. He greatly expanded the Seljuk territory and consolidated his power, defeating rivals to the south and northwest, and his victory over the Byzantines at the Battle of Manzikert, in 1071, ushered in the Turkmen settlement of Anatolia.

The Battle of Manzikert or Malazgirt was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, theme of Iberia. The decisive defeat of the Byzantine army and the capture of the Emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many Turks, travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.
