Marwar (मारवाड़) (also called Jodhpur region) is a region of southwestern Rajasthan state in western India. It lies partly in the Thar Desert. In Rajasthani dialect "wad" means a particular area. The word Marwar is derived from Sanskrit word 'Maruwat'. English translation of the word is 'The region of desert'., The Imperial Gazetteer of India, v. 17, p. 213 defines Marwar as corruption of Maru-wār, classically Marusthala or Marusthan, also called Marudesa, whence is derived the unintelligible Mardes of the early Muhamadan writers. The word means the 'region of death' and hence is applied to desert.
Region includes the present-day districts of Barmer, Jalore, lakshman nagar, Jodhpur, Nagaur, and Pali. It is bounded on the north by Jangladesh region, on the northeast by Dhundhar, on the east by Ajmer, on the southeast by Mewar, on the south by Godwar, on the southwest by Sindh, and on the west by Jaisalmer region.
