Jangladesh, also known as Jangaldesh or Janglu, was a historical region in what is now northern Rajasthan. It included the present-day districts of Bikaner, Churu, Ganganagar, Hanumangarh, and parts of Sirsa. It was bounded on the south by Marwar and Jaisalmer, and on the east by Ajmer-Merwara.
The term Jangladesh means "rough and dry country", and it is first mentioned in the Mahabharata, although it does not mention an exact location. Later Sanskrit texts, such as Bhava Prakasha and Shabdakalpadruma Kosha, suggested that the land was a hot, arid region, where trees grow with little water.
