Gurjaradesa (Gurjara country) or Gurjaratra is a historical region in India comprising the eastern Rajasthan and northern Gujarat during the period of 6th -12th century CE. Its name is believed to derive from the dominance of the Gurjara tribes in this region. The predominant power of the region, the Gurjara-Pratiharas eventually controlled a major part of North India centered at Kannauj. The modern state of "Gujarat" derives its name from the ancient Gurjaratra.
Gurjaradēśa, or Gurjara country, is first attested in Bana's Harshacharita (7th century CE). Its king is said to have been subdued by Harsha's father Prabhakaravardhana (died c. 605 CE). The bracketing of the country with Sindha (Sindh), Lāta (southern Gujarat) and Malava (western Malwa) indicates that the region including the northern Gujarat and Rajasthan is meant.
Hieun Tsang, the Chinese Buddhist pilgrim who visited India between 631-645 CE during Harsha's reign, mentioned the Gurjara country (Kiu-che-lo) with its capital at Bhinmal (Pi-lo-mo-lo) as the second largest kingdom of Western India. He distinguished it from the neighbouring kingdoms of Bharukaccha (Bharuch), Ujjayini (Ujjain), Malava (Malwa), Valabhi and Surashtra. The Gurjara kingdom was said to have measured 833 miles in circuit and its ruler was a 20-year old kshatriya, who was distinguished for his wisdom and courage. It is known that, in 628 CE, the kingdom at Bhinmal was ruled by a Chapa dynasty ruler Vyāgrahamukha, under whose reign the mathematician-astronomer Brahmagupta wrote his famous treatise. It is believed that the young ruler mentioned by Hieun Tsang must have been his immediate successor. It appears that the Gurjara country at that time comprised modern Rajasthan. Following the death of Harsha, his empire split up into small kingdoms. Gurjaradesa is believed to have become independent.
