Vaishali, Vesali or Vaiśālī was a city in present-day Bihar, India, and is now an archaeological site. It is a part of the Tirhut Division.
It was the capital city of the Vajjika League of Vrijji mahajanapada, considered one of the first examples of a republic around the 6th century BCE. Gautama Buddha preached his last sermon before his death in 483 BCE, then in 383 BCE the Second Buddhist council was convened here by King Kalasoka, making it an important place in both Jain and Buddhist religions. It contains one of the best-preserved of the Pillars of Ashoka, topped by a single Asiatic lion.
Vaishali is also home to possibly the earliest known example of a stupa, the Buddha relic stupa which is said to contain the ashes of the Buddha.
The city finds mention in the travel accounts of Chinese explorers, Faxian (4th century CE) and Xuanzang (7th century CE), which were later used in 1861 by British archaeologist Alexander Cunningham to first identify Vaiśālī with the present village of Basarh in Vaishali District, Bihar.
Vaishali derives its name from King Vishal of the Mahabharata age.
Even before the advent of Buddhism and Jainism, Vaiśālī was the capital of the republican Licchavi state. In that period, Vaiśālī was an ancient metropolis and the capital city of the republic of the Vaiśālī state, which covered most of the Himalayan Gangetic region of present-day Bihar state, India. However, very little is known about the early history of Vaiśālī. The Vishnu Purana records 34 kings of Vaiśālī, the first being Nabhaga, who is believed to have abdicated his throne over a matter of human rights and believed to have declared: "I am now a free tiller of the soil, king over my acre." The last among the 34 was Sumati, who is considered a contemporary of Dasaratha, father of the Hindu god, Lord Rama.
Vaiśālī is also renowned as the land of Amrapali, the great Indian courtesan, who appears in many folktales, as well as in Buddhist literature. Ambapali became a disciple of Buddha.
