ملکشاه ، جلال الدوله مالک شاه
Malekshah I ; third ruler of the
Seljuk dynasty who reigned after
Alp Arslan (1072-1092) : He drove the Byzantines out of
Anatolia following their defeat by his father Alp Arslan at the Battle of
Manzikert in 1071. Likewise, he reformed the calendar with the
Jalali calendar in 1079. Malekshah expanded Seljuk power into
Syria at the expense of the Fatemids of
Egypt, setting up client princes in
Edessa, Halab and
Sultan Soleyman revolted against Malekshah I and proclaimed himself the Sultan of Rum, establishing his capital at
Iznik. Soleyman expanded his realm but was killed near Antioch in 1086 by
Tutush I, the Seljuk ruler of Syria. Soleyman's son,
Kilij Arslan I, was captured and taken as a hostage by Malekshah I to
Isfahan. It is uncertain whether Tutush killed Soleyman out of loyalty to Malekshah I or simply for personal gain.
Malekshah was educated by Alp Arslan's
Nezamolmolk and ascended the throne at the age of 17. Nezamolmolk retained the principal post in the organization as Vezir. He moved the capital from
Rhagae to Isfahan.
His death, 20 days after assassination of Nezamolmolk raised many speculations which paved the way for disintegration of the Seljuk Empire.
