By approximately 1200, the influence of Buddhism across much of India had entered a period of significant decline. This shift was not the result of a single event, but rather a complex convergence of factors that eroded the foundations of the tradition within its historical homeland. Over time, the religion faced mounting challenges that fundamentally altered its standing in the region.

Several critical pressures contributed to this gradual transformation:

• Shifting patterns of royal and elite patronage that had previously sustained monastic communities.
• Intense competition from other religious traditions, including the resurgence of various schools of Hinduism.
• The inherent institutional vulnerability of large, centralised monastic complexes.
• Widespread political disruption and instability that fractured the social structures supporting Buddhist institutions.

As these pressures mounted, the once-dominant presence of the faith began to wane. While the tradition diminished significantly in the Indian subcontinent, it remained a vibrant and influential force across many other regions of Asia, where it continued to flourish and adapt to diverse cultural landscapes long after its decline in the land of its origin.
