What were the achivements of Mohenjo-Daro?
It is probably best not to talk about Mohenjo-Daro specifically, but the larger Indus Valley civilization of which it was an example. Archaeological finds at Mohenjo-Daro indicate that it had a highly organized, though not necessarily stratified society that had a bureaucratic mechanism for exacting grain tributes from area peoples. The buildings at Mohenjo-Daro, and its contemporary sites throughout the region, show remarkable precision in brick cutting and architecture. They also seem to have a high degree of division of labor, extensive trade relations with neighboring peoples, precise systems of weights and measures, and some kind of writing and numeric systems. All of these are hallmarks of an advanced civilization.
