The siege of Antioch was a military engagement between the Seljuks of Rum led by Sulieman ibn Qutalmish and the Byzantine garrison of Philaretos.

After the defeat at the Battle of Manzikert, a large part of Asia Minor fell to the hands of the Seljuk Turks.

[2] The Byzantine historian, Anna Komnene claimed that Philaretus converted to Islam and his son Basrama was against this, however, he was imprisoned and ironically asked the Seljuks for help.

[5][6] Later in December 1084, the Seljuk ruler of Nicaea, Suleiman ibn Qutalmish, left with a small army of 300 cavalry and some infantry.

A general amnesty was proclaimed; the plunder seized after the first irruption was restored and the Seljuks allowed the inhabitants to return home unmolested.
