Historically significant, Guwahati was once the ancient capital of Pragjyotishpura and Durjaya, and its landscape is dotted with numerous ancient Hindu temples, earning it the moniker "The City of Temples" [16, 17].

Among its many sacred sites are the revered Kamakhya Temple, Umananda Temple, and Navagraha Temple, drawing pilgrims and tourists alike. Beyond its spiritual allure, Guwahati is recognized as a major riverine port city and one of India's fastest-growing urban centers, playing a pivotal role in the region's commercial and cultural fabric [Britannica - Guwahati, India, Map, History, & Facts].

The GMC is structured into 60 municipal wards to facilitate efficient administration [52]. Complementing the municipal body, the Guwahati Metropolitan Development Authority (GMDA) plays a crucial role in the broader metropolitan area's planning and development.

Additionally, the Court of the District and Sessions Judge, Kamrup, established in 1920, functions within Guwahati, handling local judiciary matters [57, 58].

Guwahati stands as a significant economic powerhouse in Northeast India, serving as a principal commercial center and an important river port.
