Licchavis had a strong religious bent of mind in spite of the fact that they were vigorous, martial and highly prosperous. The main religions of the Licchavi tribes were Jainism and Buddhism. The Licchavi tribes appear to have been imbued with a strong religious spirit. The Licchavis appear to have had numerous shrines in their town as well as in the country. Even after Jainism and Buddhism had obtained a strong hold on the Licchavis of Vaishali, the great body of the people of the Vajji country as well as of the capital remained staunch followers of their ancient faith, the principal feature of which was Chaitya worship, although they had due respect for the Jaina or Buddhist sages who wandered over their country preaching the message delivered by their respective teachers.

Licchavis observed their old religious rites for a long time because initially Buddhism at the early stage was a form of faith for ascetics only, not a religious creed for all people. The Buddhists at this period formed only one of the numerous ascetic sects of Northern India; thus there was nothing unusual in the fact that many of the Licchavis who were householders and had not accepted the life of Bhikkhus. About the worship of the Licchavis it can be said that that the religious beliefs of the Licchavis were not much different from other parts of northern India. Some of the well known Chaityas of the Licchavis were Capala, Saptamraka, Bahuputra, Gautama, Kapinahya and a lot more.

Historical records say that Lord Buddha had said that as long as the Licchavis honour and esteem and revere and respect and support the Vajjian shrines in town or country they shall never decline from their position but rather they would always prosper. Lord Buddha had exercised a remarkable influence even over the fiercest of the Licchavis. Many times Lord Buddha had paid his visit to Vaishali in order to help them out from many other problems. Even many of the Licchavi women were converted to Buddhism some of the Licchavi women who had been converted to Buddhism were Siha, Jenti, Vasetthi, and Ambapali.

Some of the Buddhist books refer to the fact that many of the Vedic deities like Indra and Prajapati or Lord Brahma were worshipped by the Licchavis in the pre-Buddhist period. On the other hand Kautilya`s Arthasashtra has stated that the Licchavis used to worship many other deities besides the several Vedic deities.
