Kanishka was the greatest Kushana ruler. He ruled from his capital, Purushapura between AD 78 and 120. He also constructed a city called Kanishkapuram. Kanishka conquered Kashmir. He also defeated the Chinese and the Saka rulers of Malwa and Gujarat. Kanishka was a great patron of medicine. A new school of art called Gandhara art developed during his time. This was inspired by Buddhism, though it has some Greek influence too. Kanishka is thought to have started the Shaka Era, which was later used as the official calendar of India.
Kanishka worshipped many gods before he embraced Buddhism. Ashvaghosha, the Buddhist scholar, probably influenced Kanishka to become a Buddhist. Like Ashoka, Kanishka also worked for the spread of Buddhism. He took steps to repair many old monasteries. New ones were also built. During his time, Buddhism spread to China, Japan, Central Asia and Tibet. Kanishka is considered as the second Ashoka because of all these activities.
