Farsi Tutor Principality (Salgurlular) (1147-1284)   

          In the period of Mes'ud who was the sultan of Iraq Seljuk State, this tutor principality was founded by the declaration of independence of the Tutor Sungur from Oguz Salgur (Salur) tribe who provided service in the Farsi region of Iran since the beginning period of Seljuk State (1147). The capital city of this principality was Shiraz. Pursuant to the death of Sungur (1116), his son, Zengi had to recognise the domination of Iraq Seljuk State and this situation continued until the collapse of the Seljuk State (1194). Sa'ad I (Zengi's son) who had attained superiority among his brothers became the ruler of Salgurlu in the year of 1203. He then developed his country with public works. Pursuant to Sa'ad who had once been taken prisoner by Harzemshah State (died in 1231), his son, Ebu Bekir (died in 1260) replaced him. The Iranian poet, Sa'di-i Şirazi had written his important works under the protection of this tutor. The tutor principality was submissive to the Ilhanli Mongolians. Then, the daughter of Sa'ad II was married with the son of Hulagu, the Mongolian ruler. Upon the death of this lady in the year of 1284, the dynasty came to an end.
