yes it is a mahajanapada.
Magadha had a monarchy type of government but Vajji developed a democratic type of government
Mahajanapada refers to the sixteen ancient kingdoms or republics that existed in the Indian subcontinent before the rise of the Mauryan Empire. These mahajanapadas played a significant role in shaping early Indian history and politics.
Lichchhavis were a republican mahajanapada and were ruled by a group elected by the common people.There were no king.
During the Mahajanapada period in ancient India, taxes were collected in various forms such as produce, cattle, and goods. The tax rates varied depending on the region and the ruler, but commonly ranged from one-sixth to one-fourth of the produce.
Sanskrit was the language of Greater India, Vedic India (same thing), and Greater Iran. It was the language of the Vedas. It was closely tied with its counterpart, Avestan, the official language of Greater Iran and the Avesta. Sanskrit is still spoken today in India, numbering in about 10,000 active, fluent speakers. It originated before the Mahajanapada times of Ancient India. It was first used for Vedic culture, which again, sprouted in Greater India (composite of today's North India, Pakistan, and Afghanistan).
