The north-western region of India, which incorporates Rajasthan, remained in early history for the most part independent from the great empires consolidating their hold onthe subcontinent. Buddhism failed to make substantial inroads here; the Mauryan Empire (321-184 BC), whose most renowned emperor Ashoka converted to Buddhism in262 BC, had minimal impact in Rajasthan. However, there are Buddhist caves and stupas (Buddhist shrines) at Jhalawar, in southern Rajasthan.
The Indus Valley Civilization, one of the world's first and oldest civilizations, was located in parts of what is now Rajasthan. Kalibangan in Hanumangarh district, Rajasthan was a major provincial capital of the Indus Valley Civilization. It is believed that Western Kshatrapas were Saka rulers of the western part of India Rajasthan was inhabited long before 2500 BC and the Indus Valley Civilisation had its foundation here in north Rajasthan itself. The Bhil and the Mina tribes were the earliest dwellers of this area.Ancient Hindu scriptural epics make reference to sites in present day Rajasthan. The holy pilgrimage site of Pushkar is mentioned in both the Mahabharata and Ramayma.
Rajasthan was fragmented in competing kingdoms. Perhaps it was during this era by their influence through wealth and power the Rajputs persuaded the Brahmins to link them with the sun, the moon and the fire god.With the passage of time they were divided into 36 royal clans. Rajasthan finally settled for a long and lasting reign under the colourful and vibrant Rajputs. and it’s a surprise that they lasted as long as they did. Considering that they were at a constant state of aggression; if not with a foe, then with each other. After the 14th century their influence declined in the area.
The fall of the Gupta Empire, which held dominance in northern India for nearly 300 years, until the early 5th century, was followed by a period of instability as various local chieftains sought to gain supremacy. Various powers rose and fell in northern India. Stability was only restored with the emergence of the Gurjara Pratihar as, the earliest of the Rajput dynasties which were later to hold the balance of power throughout Rajasthan. The emergence of the Rajput warrior clans in the 6th and 7th centuries played the greatest role in the subsequent history of Rajasthan.
