History
The Murghab river fans out into an inland delta north of the Kopet Dag, and settled farmers used its water from the Bronze Age. Gonur Tepe, in the desert north of Mary, was a walled centre of what archaeologists call the Bactria– Margiana Archaeological Complex around 2000 BC, with palaces, fire altars and rich graves. Later the oasis was Margiana, a province of the Persian Empire, and under Alexander's successors a new walled city, Antiochia Margiana, rose at Merv.
Merv then grew for more than a thousand years, each new city built beside the last. It was a Sasanian stronghold, the base from which Arab armies advanced into Central Asia, and the city where the Abbasid revolt was launched in 747. Under the Seljuks in the 11th and 12th centuries it became their eastern capital and one of the largest cities in the world, with libraries and the observatory where Omar Khayyam is thought to have worked. Sultan Sanjar died in 1157, and in 1221 the Mongols destroyed the city and killed much of its population.
Along the Amu Darya, Amul, near today's Turkmenabat, was an important river crossing on the route from Merv to Bukhara, and the region long lay under the Emirate of Bukhara. The Russians took the Merv oasis in 1884 and founded Mary beside the old ruins, and in Soviet times both provinces became cotton lands watered by the Amu Darya and the Karakum Canal.
