Marw al-Rudh

'Marw on the river'), locally used to be known by the older variants Marwarudh (مروروذ) and Marrudh (مروذ),[1] was a medieval settlement in Khurasan.

[2] The town existed already in pre-Islamic times, its foundation being attributed to the Sasanian king Bahram Gur (reigned 420–438).

Its original name in Persian was Marwirōd (مرورود) or Marvirot (Mrot in Armenian), which survived in the later Arabic nisbas of al-Marwarrudhi and al-Marrudhi.

[2] The Abbasid-era geographers report that the town was the centre of a flourishing agricultural region, with a number of dependent suburbs such as Qasr-i Ahnaf.

[2] Although the town appears to have escaped the destruction of Marw al-Shahijan by the Mongols, it fell into ruin under the Timurids and was largely abandoned.
