The introductory portions of the Cullakalinga Jātaka and the Ekapaṇṇa Jātaka mention the Licchavi as having 7,707 Rājās. The number is one of convention, and unlikely to have been exact. It does demonstrate that Licchavi, unlike most of its neighbours, was not an absolute monarchy.
Ultimate authority rested with the 7,707 raja who met each year to elect one of their member as ruler and a council of nine to assist him. It was far from a democracy as only a small portion of the Licchavi population qualified to vote. Those with raja status were only the male heads of households who belonged to the kshatriya varna.
The seat of the Licchavi administration was in Vaiśālī, the capital of the Vajjiian confederacy. The Rājā was the highest executive and judicial authority.The introductory portion of the Bhaddasāla Jātaka mentions about a tank, the water of which was used for the Abhiṣeka (the coronation) of the Gaṇarājas of Vaiśālī.
The assembly hall where these Gaṇarājas met for discussion was known as the Santhāgāra.
