Dizmar-e Sharqi Rural District

Dizmar has been first mentioned by the renowned historian Hamdallah Mustawfi in the mid fourteenth century, "Dizmar is a district in the north of Tabriz which includes more than 50 villages ..." [3] Mardanaqom, was also mentioned by Hamdallah Mustawfi as a thriving village.[3][4] The landmark, manifesting ancient history of the district, is an ancient plane tree in Kavanaq village (included on the map). The tree is about 3 meter in diameter and is said to have lived for 500 years. Moreover, on a mountain between Kavanaq and Mardanaqom, there is a castle dating from Sasanian era. It was used as a jail for high-ranking officials during Khwarazmian reign.[5]

In the wake of White Revolution (early 1960s) many clans of Qarāca Dāġ tribes used Dizmar as their winter quarters.[6] Eastern part of Dizmar was declared a part of Khoda Afarin County in 2011 [7] and Mardanaqom was designated as its capital.
