Mughan plain is a plain stretching from northwestern Iran to the southern part of the Republic of Azerbaijan. The highest density of irrigation canals is in the section of the Mughan plain which lies in the Republic of Azerbaijan. It is located on the bank of the Aras river extending to Iran.
The Mughan plain consists of five cities: Bilehard, Parsabad, Jafarabad, Germi and Aslan Duz. One-third of the plain is located in Iran and the rest is in Azerbaijan.
By the Chalcolithic period (c. 4500–3500 BCE), the Moghan Plain was integrated into the sphere of the Kura–Araxes culture, a major cultural phenomenon in the South Caucasus known for its red-black pottery and early metallurgical development. These communities built fortified settlements, cultivated crops, and developed trans-regional trade networks.
