The Rajasthani hill-station of Mt Abu was the geographical and spiritual center of a territory known in ancient times as Gurjara. This territory covered northern Gujarat and southwest Rajasthan, and it shared a cultural affinity with the neighboring region of Maru, covering western Rajasthan. In more modern times, Gurjara evolved into Gujarat, while Maru became Marwar. The domain of the Pratihara Rajput rulers of Mandor covered both these regions and the temples built at Osian are categorized under the Maru-Gurjara style of architecture. The agnikula legend of later times also points to Mt Abu as the original home of the Pratiharas. This is why the Pratihara rulers are sometimes described as Gurjara, Gurjararaja, Gurjaranatha, in the records of their contemporaries.
Another related principality of this era was Nandipuri in southern Gujarat, which was founded by Dadda, who is identified with the youngest son of Harichandra Pratihara. This family claims to have been born in the lineage of the kings of Gurjara (Gurjara nripa vamsa) but the clan name of Pratihara is missing from all their records. It is plausible that Gurjara was the original name of a clan based in Mt Abu, after whom the territory got its name, and which sent different branches south into Gujarat and north into Mandor. However no record of such a clan has been unearthed. And if the Pratiharas of Mandor were descended from such a clan, it is inexplicable that the name Gurjara as used in the sense of a clan, is completely missing from their records or those of the Imperial Pratiharas who rose up from Ujjain.
There are many more references to Gurjara as a province, than as a clan. The Kuvalayamala Kaha, was composed in Prakrit by Uddotana in 779 CE, at Jalor in Rajasthan at the same time as the Pratihara empire was being formed. It makes reference to the adjoining territories of Maru, Malava, Gurjar, Lata, Madhyadesa, Takka, and Sindhu. The 7th century Chinese pilgrim Hiuen Tsang has spoken of a kingdom in Rajasthan as follows: "The king is of the Kshatriya caste. He is just twenty years old, He is distinguished for wisdom and he is courageous. He is a deep believer in the law of Buddha and highly honours men of distinguished ability." Hiuen Tsang named this kingdom ku-che-lo, which can be identified as Gurjara, with its capital at pi-lo-mo, usually identified with Bhinamalla near Mt Abu. In Bana's Harsha Charita it is said that in the 6th century Prabhakarvardhana of Thaneswar (in modern Haryana) fought the Hunas (lingering on in the Punjab and Kashmir), the king of Sindhu (modern Sindh), the king of Gurjara (Gujarat+SW Rajasthan), the lord of Gandhara (northwest), the ruler of Lata (southern Gujarat), and that of Malava (western Madhya Pradesh).
Even in more modern times the word Gujar was being used in territorial sense, rather than tribal, in certain parts of India. For instance the 1879 Rajputana gazetteer reports that in Marwar the word Gujar is used to designate Gujarat. Meanwhile the 1883 Gazetteer of the Bombay Presidency reports that in Maharashtra vani (traders) were named after the provinces of their origin; hence the word Gujar meant a Gujarat Vani while Marwari was used for a Marwar Vani. Apart from these references there are numerous communities still bearing the cognomen of Gurjar, pointing to its geographical origin, the most prominent of whom are the Gurjara Brahmins.
The core of the territory known as Gurjara became Godwad from the 10th century onwards.
