Trace the spread of Buddhism in south India and explain why it declined after the early medieval period.

Buddhism reached south India through Ashoka's missions and through trade routes along the coasts. Monks, merchants and kings supported it for nearly a millennium. After about the 8th century it gradually merged into a revived Hindu tradition. It was absorbed more than it was wiped out.

Spread of Buddhism in South India

• Mauryan phase: Ashoka's Rock Edicts II and XIII name the Cholas, Pandyas, Satiyaputras and Keralaputras as neighbouring peoples. His missions also carried the Dhamma to Sri Lanka.
• Andhra heartland: Under Satavahana and Ikshvaku patronage, Amaravati and Nagarjunakonda became leading stupa and monastery centres and gave rise to a distinct southern school of art.
• Tamil region: The Tamil epic Manimekalai shows Buddhism active in port cities and in Kanchipuram. Later, the Chudamani Vihara at Nagapattinam was built with Chola permission, which shows Buddhism still had a coastal network in the 11th century.
• Kerala: The Ay king Vikramaditya Varaguna's Paliyam copper plates record grants to the Buddhist shrine Srimulavasam. Granite Buddhas in meditation posture, such as Karumadi Kuttan, survive along the Alappuzha–Kollam backwaters [2]. P.C. Alexander's 1949 study was the first systematic survey of these remains [1].

Causes of Decline

• Bhakti movement: Between about the 6th and 9th centuries, the Alvars and Nayanars spread an emotional, Tamil-language devotion. It drew lay followers away from the monasteries.
• Loss of royal patronage: Kings turned to Shaiva and Vaishnava temples and gave land grants to Brahmins and temples.
• Philosophical revival: Adi Shankara's Advaita took over Buddhist ideas in debate. The Buddha was then reworked as an avatar of Vishnu.
• Monastic isolation: Buddhism came to depend on its monasteries and lost touch with ordinary lay followers. When the monasteries declined, no community remained to carry it on.
• Absorption, not destruction: In 1926 villagers at Pallikkal in Travancore were worshipping a Buddha image as their local deity [2]. The stone survived but its Buddhist identity did not.

Buddhism in south India rose with Ashoka's missions, coastal trade and royal patronage. It faded as Bhakti, temple-based kingship and Brahmanical philosophy took over its social role. Recording and protecting surviving images under the AMASR Act, 1958 would preserve this shared heritage. It would also reflect the Constitution's commitment to protecting India's composite culture under Article 51A(f).
