Vajji or
Vrijji was a confederacy in Ancient India . It was one of the principal
mahājanapadas of Ancient India. Both the Buddhist text
Anguttara Nikaya and the Jaina text
Bhagavati Sutra (
Saya xv
Uddesa I) included Vajji in their lists of
solasa (sixteen) mahājanapadas. The name of this mahājanapada was derived from one of its ruling clans, the Vṛjis. The Vajji state is indicated to have been a republic. This clan is mentioned by
Pāṇini,
Chanakya and
Xuanzang.
