Mohenjo-daro – which means "mound of the dead men" in Sindhi – was the largest city of the once-flourishing Indus Valley (also known as Harappan) Civilisation that ruled from north-east Afghanistan to north-west India during the Bronze Age. Believed to have been inhabited by at least 40,000 people, Mohenjo-daro prospered from 2500 to 1700 BCE.
