Amir Abu'l-Abbas Fadl, better known as Fadluya (also spelled Fadlawayh), was a Kurdish[1][2] chieftain of the Shabankara in Fars.
[2] Earlier in his life, Fadluya's father Ali sent him to Saheb-e Adel, who was then the vizier to the Buyid ruler Abu Kalijar.
[5] He offered an annual tribute of 27 million dirhams in return for the Seljuks letting him remain ruler of Fars.
[5] He stopped sending the annual tribute, proclaimed himself an independent ruler, and took up a defensive position at the fortress of Khvorsha near Jahrom.
[5] Nizam al-Mulk began a siege, which only lasted for a relatively short time before the defenders surrendered due to lack of water.
