Explanation:

Introduction:
Amravati, located in present-day Andhra Pradesh, India, was once a flourishing Buddhist settlement and a significant center for Buddhist art and culture. However, it eventually declined and did not survive as a prominent site.

Reasons for Amravati's decline:

1. Lack of preservation:
Amravati's decline can be attributed to the lack of proper preservation efforts. Over time, the site suffered from neglect and deterioration, leading to its eventual decline. The intricate Buddhist sculptures and stupas were not adequately protected and maintained, resulting in their degradation.

2. Changing religious landscape:
As time progressed, the religious landscape of India underwent significant changes. Buddhism, which had once flourished in Amravati, faced a decline in patronage and popularity. Hinduism and other religious traditions gained prominence, leading to a shift in focus and resources away from Buddhist sites like Amravati.

3. Shift of political power:
The decline of Amravati can also be linked to the shift of political power in the region. As political dynamics changed, the rulers and patrons who had previously supported and contributed to the development of Amravati may have changed their interests and priorities. This shift in patronage and support could have adversely affected the preservation and growth of the site.

4. Competition from other stupas:
Amravati faced competition from other stupas and Buddhist sites across India. As Buddhism spread to various regions and gained popularity, new centers for Buddhist art and culture emerged. These new centers attracted attention and resources, diverting them away from Amravati.

Conclusion:
In conclusion, Amravati did not survive as a prominent site due to a combination of factors including the lack of preservation, changing religious landscape, shift of political power, and competition from other stupas. These factors collectively contributed to the decline and eventual obscurity of Amravati as a significant Buddhist center.
