Lurestan province is one of the oldest territories of Iran. In the third and fourth millennium BC. immigrant tribes settled down in the mountainous area of the Zagross and the region of 'Bain-ol-Nahrain' (the current Dorood area). According to the records, the said tribes were the 'Lulubi', 'Mana'ie', 'Kasie', 'Gootie', 'Amada' and 'Parsoa' tribes or clans. In the second millennium BC. the Kasie tribe were made extinct due to the attack of the forceful government of Ilam.
During the conquest of Alexander to Iran, this territory came under their jurisdiction. During the Sassanian reign, the 'Pasth Kooh' and 'Pisht Kooh' territories came under the rule of one of the members of the reputed 'Hormozan' family. In the year 21 AH. after the conquest of 'Halvan', the Arabs ruled over the northern area and Nahavand and parts of southern Lurestan. In the year 22 AH 'Hossnooyeh-e-Kord' brought this territory under his own jurisdiction, till the year 500 AH.
On Mongols gaining control in Iran, Lurestan was divided into two parts. 'Lor-e-Bozorg' and 'Lor-e-Koochak' (greater and smaller Lurestan). The 'Attabakan' or 'Lords' of the 'Lor-e-Bozorg' ruled in this area from about the first half of the 8th century AH. till the first half of the 9th century. The 'Attabakan of the 'Lor-e-Koochak' ruled here from 508-1006 AH. till the Safavid era, when Shah Abbas proved victorious and Lurestan came under the hands of an 'Amir' named 'Hossain' which lasted till the 'Qajar dynasty'.
