The Theravada tradition of Buddhism, which emphasizes the original teachings of the Buddha, has remained the dominant form of Buddhism in Sri Lanka.
Buddhism was introduced to Sri Lanka in the 3rd century BCE during the reign of King Devanampiya Tissa. The introduction is attributed to Arahat Mahinda, the son of the Indian Emperor Ashoka. He brought the Theravada form of Buddhism to the island, which became the dominant tradition. Buddhism has deeply influenced Sri Lankan culture, influencing art, literature, architecture, and daily practices. Festivals, rituals, and traditions are often tied to Buddhist teachings and stories.
