The Anuradhapura period (377 BCE1017 CE) began with the establishment of the Anuradhapura Kingdom in 380 BCE during the reign of Pandukabhaya. Thereafter, Anuradhapura served as the capital city of the country for nearly 1,400 years. Ancient Sri Lankans excelled at building certain types of structures such as tanks, dagobas and palaces. Society underwent a major transformation during the reign of Devanampiya Tissa, with the arrival of Buddhism from India. In 250 BCE, Mahinda, a bhikkhu and the son of the Mauryan Emperor Ashoka arrived in Mihintale carrying the message of Buddhism. His mission won over the monarch, who embraced the faith and propagated it throughout the Sinhalese population.
