The Gurjara Prathiharas dynasty was founded by Harichandra in the 6th century CE. However, it was under the leadership of Nagabhata I (730-760 CE) that the Gurjara Pratiharas became a major power in northern India. The dynasty is thought to have originated from a mix of the Alchon Huns and native Indians.
The Gurjara-Pratiharas first ruled from Ujjain, and later from Kannauj. They played a key role in stopping Arab armies from moving east of the Indus River. The Gurjara-Pratiharas declined due to dynastic strife. The final blow came when Indra III of the Rashtrakutas raided and devastated their capital of Kannauj.

1. The Paramaras of Malwa
2. The Chandelas of Bundelkhand
3. The Chaulukyas (Solankis) of Gujarat
4. The Chauhans of Ajmer
