answer:

indus civilization. indus civilization, also called indus valley civilization or harappan civilization, the earliest known urban culture of the indian subcontinent. the nuclear dates of the civilization appear to be about 2500–1700 bce, though the southern sites may have lasted later into the 2nd millennium bce.oct 23, 2019

city walls are not effectively fortified to withstand attack in comparison with cities from the early historic era, and there is a paucity of well designed weapons, and there is no depiction of warfare or conquest on objects that have survived

the remains of the indus valley civilization cities indicate remarkable organization; there were well-ordered wastewater drainage and trash collection systems and possibly even public baths and granaries, which are storehouses for grain. most city-dwellers were artisans and merchants grouped together in distinct neighborhoods. the quality of urban planning suggests efficient municipal governments that placed a high priority on hygiene or religious ritual.

one of the ways historians know about the maritime trade network operating between the harappan and mesopotamian civilizations is the discovery of harappan seals and jewelry at archaeological sites in regions of mesopotamia, which includes most of modern-day iraq, kuwait, and parts of syria. long-distance sea trade over bodies of water—such as the arabian sea, red sea and the persian gulf—may have become feasible with the development of plank watercraft that were each equipped with a single central mast supporting a sail of woven rushes or cloth.

harappa indicate that they were part of a unified government with extreme organization this evidence suggests that this civilization did not have social classes.

the indus valley religion is polytheistic and is made up of hinduism, buddhism and jainism. there are many seals to support the evidence of the indus valley gods. some seals show animals which resemble the two gods, shiva and rudra. the indus people worshipped a father god who may have been the forefather of the race.
