Bilarghu, also Pilargh'ou, was a Mongol general of the ruler Ghazan during the end of the 13th and the beginning of the 14th century.
During the Mongol campaigns of 1299 in Syria, Bilarghu was put in charge of the rear-guard on the Euphrates, in command of 10,000 men.
In 1307, Bilarghu, who already had poor relations with Hethum II, was involved in an internal plot leading to his assassination of the Armenian rulers.
The opposing faction went to see Bilarghu, and accused Hetoum of plotting an insurrection against the Mongols.
[2][3] Oshin, brother of Hetoum, immediately marched against Bilarghu and vanquished him, forcing him to leave Cilicia.
