[2] Biradost has been described as "a central upland consisting of valleys and partial basins surrounded by border ranges".
In the 16th century, the emirate ruled Targavar, Margavar, Dul, Somay, and western Urmia.
The founder of the emirate was Yusuf Beg who received the title Gazi Qiran by Ismail I in 1510 as he was given Somay, Targavar and Dol at the Ottoman front.
As relations with the Ottomans improved, he received land around Erbil, Baghdad and Diyarbakir by Suleiman the Magnificent after the Battle of Chaldiran in 1514.
Gazi Qiran ruled until his death around 1543 and would be considered one of the most important Kurdish rulers in later generations.
