Why did Buddhism vanish from its birthplace only to return centuries later?

In short: Buddhism once dominated India, yet by the 19th century, it was virtually extinct. Its decline was not a single event but a slow erosion caused by shifting royal patronage, monastic isolation, and the rise of devotional Hinduism. Today, a modern revival is reshaping the faith through mass conversion.

The decline of Buddhism in India was a complex, centuries-long process. By the 12th century, the collapse of the Pala dynasty marked a point of no return. While some scholars point to Buddhism’s inherent tolerance leading to its reabsorption into a revitalized Hindu tradition, the primary cause was likely the religion's transformation into a strictly monastic movement. As monasteries grew wealthy, they became disconnected from the lay population, relying on indentured labor rather than community support. This isolation left the faith vulnerable when Muslim invaders sacked these institutions in the 12th and 13th centuries, as the laity felt little incentive to rebuild.

Earlier pressures had already weakened the sangha. In the 6th century, the Hun ruler Mihirakula launched a campaign of persecution, destroying monasteries across Gandhara. Following the Gupta Empire, the regionalization of India meant that royal patronage—once the lifeblood of Buddhist expansion—shifted toward Hindu sects like Shaivism and Vaishnavism. As Hindu devotional movements gained popularity among the masses, Buddhist institutions lost both their financial base and their relevance to public life, effectively ceding spiritual authority to the Brahmins.

The contemporary revival of Buddhism in India is largely a 20th-century phenomenon. In 1956, Bhimrao Ramji Ambedkar, a leader of the Scheduled Castes, initiated a mass conversion of hundreds of thousands of Hindus in Maharashtra. Seeking a path free from caste distinctions, Ambedkar turned to Buddhism, viewing it as a rational alternative to the Hindu social order. This movement, which emphasizes lay leadership and Ambedkar’s own interpretations, has since grown to include several million followers, marking a dramatic shift from the near-total disappearance of the faith in the 19th century.
