Ashoka, also known as Asoka or Aśoka, and popularly known as Ashoka the Great, was Emperor of Magadha from c. 268 BCE until his death in 232 BCE, and the third ruler from the Mauryan dynasty. His empire covered a large part of the Indian subcontinent, stretching from present-day Afghanistan in the west to present-day Bangladesh in the east, with its capital at Pataliputra. A patron of Buddhism, he is credited with playing an important role in the spread of Buddhism across ancient Asia.
