Compare and contrast political religious and social characteristics of Harappa society to those of Mesopotamia and Egypt?

Harappa society, part of the Indus Valley Civilization, exhibited a centralized urban planning system, but its political structure remains less understood compared to the more documented monarchies of Mesopotamia and Egypt. Religiously, while Harappans likely practiced a form of animism and fertility worship, Mesopotamia and Egypt had structured polytheistic religions with elaborate rituals and deities governing natural and societal elements. Socially, Harappa showed signs of relatively egalitarian communities, while Mesopotamia and Egypt had more pronounced social hierarchies with distinct classes, including priests and rulers. Despite these differences, all three civilizations shared agricultural foundations, urban centers, and trade networks that facilitated cultural exchange.
