(
c. 11th – 13th centuries) Muslim
Turkmen dynasty that ruled Persia, Iraq, Syria, and Anatolia. Selj
uq was the chief of a nomadic Turkish tribe. His grandsons Chaghri Beg and
Toghrïl Beg conquered realms in Iran. Under
Alp-Arslan and Malik-Shah, the empire came to include all of Iran, Mesopotamia, Syria, and Palestine; Alp-Arslan's victory over the
Byzantine Empire at the Battle of
Manzikert led to several
Crusades. Adherents of Sunnite Islam, the Selj
uqs adopted Persian culture, and under them the Persian language partly displaced Arabic as a literary language in Iran. By 1200 Selj
uq power remained only in their sultanate of R
um in Anatolia, which collapsed in a war against the
Khwarezm-Shah dynasty in 1230 and was overrun by
Mongols in 1243.
