Yarankash

Yarankash (or Yaranqash) (died 1146) was a Frankish slave who assassinated his owner Zengi, the atabeg of Aleppo. According to Damascene chronicler Ibn al-Qalanisi:

Yaranqash stabbed the atabeg numerous times and then fled to the fortress of Qal'at Ja'bar, and then from there to Damascus, "in the confident belief that he would be secure there, openly putting forward his action as a claim to consideration, and imagining that he would be made welcome." The governor, Mu'in ad-Din Unur, instead had him arrested and sent him to Zengi's son Nur al-Din in Aleppo. Nur al-Din sent him along to his brother Sayf al-Din Ghazi I in Mosul, who had him executed.
