Kashmir due to its location on the border between South and Central Asia remained one of the most significant hubs of contact during the early stages of history. The historical event of Buddhism's advent in Kashmir had a significant impact on how the religion developed and spread throughout Central Asia. The earliest historical treatises on Kashmir, Nilmatapurana and Rajatarangini, contain literary proof that the Buddhist faith has been practiced in the Kashmir valley since its inception. Even though Buddhism was widespread in the region even before Emperor Asoka came to power and had the support of both Buddhist and Hindu kings, it is believed to have become more popular in Kashmir during his reign.
