Karakum Desert

The Karakum near Merv formed the dry surroundings of an oasis sustained by the Murghab River. Cultivation depended on the division and control of water, while settlement was concentrated where channels could carry it across the delta. The relationship between irrigated ground and neighbouring desert made damage to hydraulic works a direct threat to the survival of communities.

In the later eighteenth century, the struggle between Merv's Qajar rulers and Shah Murad of Bukhara transformed this landscape. Shah Murad's campaigns culminated in the destruction of the oasis's irrigation system and the removal of many inhabitants toward Bukhara. Historical sources differ over the exact dating of the dam's destruction within the 1780s, but agree on its importance to the collapse of cultivation and settlement. The consequences extended beyond a fallen town: the interruption of water reshaped the oasis margins, changing the boundary between productive land and the Karakum that surrounded it.
