Answer:

The place near Lothal where the mature Harappa culture degenerated and transformed itself into other cultures is Rangpur.

Explanation:

The mature Harappa culture, also known as the Indus Valley Civilization, flourished in the northwestern regions of the Indian subcontinent from approximately 2600 BCE to 1900 BCE. It was characterized by well-planned cities, advanced drainage systems, standardized weights and measures, and an extensive trade network.

However, towards the later stages of the Harappa culture, there was a gradual decline and transformation into other cultures. Rangpur, located near Lothal, is one such place where this transformation is evident.

Reasons for Degeneration:

1. Environmental Factors: Rangpur's proximity to the coast exposed it to changing environmental conditions such as sea-level fluctuations, erosion, and salinity ingress. These factors could have affected agricultural productivity and disrupted the economic stability of the region.

2. Trade Disruptions: The decline of the Harappa culture coincided with a decline in long-distance trade networks. The loss of trade connections may have impacted the economic prosperity of Rangpur, leading to a decline in the overall culture.

Transformation into Other Cultures:

1. Post-Harappan Culture: After the decline of the Harappa culture, Rangpur witnessed the emergence of the post-Harappan culture. This culture was characterized by smaller settlements, a shift towards rural agriculture, and a decline in urban planning and infrastructure.

2. Painted Grey Ware Culture: Rangpur also witnessed the influence of the Painted Grey Ware culture, which emerged around 1200 BCE. This culture was characterized by the use of distinctive pottery with painted designs and marks the transition from the late Vedic period to the early Iron Age.

Conclusion:

The transformation of the mature Harappa culture into other cultures near Lothal, specifically in Rangpur, can be attributed to various factors such as environmental changes, disruptions in trade networks, and the emergence of new cultural influences. Understanding these transformations provides insights into the complex dynamics of ancient civilizations and their ability to adapt and evolve over time.
