Humanity geography of Alamoot (Alamut) and Roodbar 
Ali Hayati
Despite the suitable environmental condition on the mountain slope of Alborz and authentic evidence of ancient human existence in the former-said human origin , ethnical root of Alamoot and Roodbar men can be found in the historical and ethnical background of Alborz habitant .
Alamoot and Roodbar have been part of Deylam territory and Deylam lived independent of Iran emperor and ruler dynasty before and after Islam religion appearance .
Even until late 4th  century of Higrae, Alamoot and Roodbar preserved the position of being capital(takhtgah ) of Deylam , the situation that commenced years before Islam appearance .   
 
Humanity origin:
Alborz mountain range comprises unique and special qualities by having mountains , mountain side , valleys, forest , suitable slopes , benefiting environmental conditions and its reposing between two natural marks which includes the sea on the north and plateau on the south edge .
Alamoot and Roodbar which is located in the heart of Alborz ,inevitably was considered as an access route .
This region by consisting running water from north of alborz and southern plateau seemed to be in an appropriate condition as a habitat and hunting ground .
Primitive humankind made its way through the mentioned land while he was passing its gorges and routes and opted the place as a suitable residence in nice climate seasons or just because of the necessity .

Regarding the settlement of Roodbar-e-Alamoot in the center part of Alborz , with all its elevated mountains and deep and arduous valleys , the land has always been considered not only as the pass way of the ancient human beings , but also as a safe habitat for his children .
Present residents living in this region are the remaining generation of ancient natives and immigrants who had migrated by their own choice    or under compelling circumstances .
Iranian -Hindu tribes who migrated in 2000 AD from the regions between Seyhoon and Jeyhoon rivers to capture more fertile fields , entered northern lands including the edges of Caspian sea .
Part of the immigrants moved throughout the forest and the ultimate border of Gilan via the access route from northern part of Alborz to its southern part and settled on in Deylamestan which continues to the Alborz mountainside .(Sartip poor -1356-P102-112)
The other immigrant group were Mazdakian who ran away from the reign of Qobad and Khosro Anooshiravan and became refugee in Deylam which was ruled independent of Iran Sultanate .However before these refugees there were some Zoroastrians who accepted Mazdak religion and had lived in that region many years ago even before Islam appearance .
The author of Alfehrest in the 4th  century of Higrae says :
Mazdaki group were scattered in Azarbayjan ,Armenia , Deylam , Hamedan , Dinvar , Isfahan and Ahvaz and they were Zoroastrians who accepted Mazdak . ( Ebn-e- Nadim , 1346, P116)
There were Zeydian and Sadat group who scaped the pressure of their ruling monarchy . Very probably Alavian and a group of Ismailie immigrated to this region subsequent to the time Ismailie ethnic initiated ruling in the region .
The last generation migrated to the mentioned territory were Lor , Kord and Turkish group whom were moved during Safavid and Qajar kingdom .(Rashvand , 1376 , P23-56 )
Regarding the probes made into the subject , there seems to be no present Mazdak , Ismaili or Zoroastrian groups  in the region .
It is likely that they accepted the dominating religion of their region or moved away based on the ethnical and religious discriminations .
 A group of Lor , Kord and Turkish tribes who had moved to this area by the order of Shah- Abbas-Safavi and subsequent to that inQajar kingdam by the order of Agha-mohammad-khan returned to their hometown by the end of the latter kingdom .
Meanwhile , those who settled on in the region , isolated their tribal life style and initiated a new life in accordance with the natives style .
During the Pahlavi reign their tribal life style commenced to weaken in a way that they lived just like the native habitants of the region .
These tribes consist of Rashvand ,Chegini , Qiasvand , Bajelan ,Behtooi, Mafi ,Siahgali , Jilaki who dispersed in the whole area (Varjavand , 1374, P456-459 )

The majority of Turkish group live in seven villages in Roodbar-e-Alamoot which four of these villages comprising Kafarkosh , Madan ,Aveh have fully Turk habitants .
Yet the ratio for Dehak and Laman village is half of the total population .
Moreover there are dispersed Turk population in Roodbar-e-Shahrestan and Khosrood .
There lives another tribe named Maraghi which live in 17 villages of the region . Their customs and life style is rather different with the rest of the habitants in the area .
Although they believe in their origin to be from Medina and Maraghe and claim to have an old manuscript as the evident of their migration to this land but no authentic evidence has been found until now to verify their immigration from the claimed destination .
