Merv - Geography

Geography

The oasis of Merv is situated on the Murghab River that flows down from Afghanistan, on the southern edge of the Karakum Desert, at 37°30’N and 62°E, about 230 miles (370 km) north of Herat, and 280 miles (450 km) south of Khiva. Its area is about 1,900 square miles (4,900 km2). The great chain of mountains which, under the names of Paropamisade and Hindu Kush, extends from the Caspian Sea to the Pamir Mountains is interrupted some 180 miles (290 km) south of Merv. Through or near this gap flow northwards in parallel courses the Tejen and Murgab rivers, until they lose themselves in the Karakum Desert. Thus they make Merv a sort of watch tower over the entrance into Afghanistan on the north-west and at the same time create a stepping-stone or étape between north-east Persia and the states of Bokhara and Samarkand.

Merv is advantageously situated in the inland delta of the Murghab River, which flows from its source in the Hindu Kush northwards through the Garagum desert. The Murghab delta region, known to the Greeks as Margiana, gives Merv two distinct advantages: first, it provides an easy southeast-northwest route from the Afghan highlands towards the lowlands of Karakum, the Amu Darya valley and Khwarezm. Second, the Murgab delta, being a large well-watered zone in the midst of the dry Karakum, serves as a natural stopping-point for the routes from northwest Iran towards Transoxiana – the Silk Roads. The delta, and thus Merv, lies at the junction of these two important routes: the northwest-southeast route to Herat and Balkh (and thus to the Indus and beyond) and the southwest-northeast route from Tus and Nishapur to Bukhara and Samarkand.

This place was an important stop on the Silk Road during the time of the Han dynasty. Here merchants could trade for fresh horses or camels and this was a very important oasis city.
