Why were the pratiharas known as the gurjara-pratiharas?

The Pratiharas were known as the Gurjara-Pratiharas because they originated from the region of Gurjara, which roughly corresponds to present-day Gujarat and parts of Rajasthan. This term highlights their ethnic and geographical identity, linking them to the Gurjara people. The Gurjara-Pratiharas became a prominent dynasty in northern India from the 6th to the 10th centuries, known for their military prowess and cultural contributions, particularly in architecture and art. Their rule played a significant role in protecting northern India from invasions, especially during the rise of Arab forces.
