There is no evidence of the rulers of the Indus Valley Civilisation. However, the Indus Valley Civilisation was a large and complex civilisation that flourished in the Indian subcontinent between 2500 and 1900 BCE. It was one of the earliest civilisations in the world and was spread over a large area, including present-day India, Pakistan, and Afghanistan. The Indus Valley Civilisation was highly developed and had many advanced features, including a well-developed system of writing, a decimal system of weights and measures, and a sophisticated system of irrigation and agriculture. The Indus Valley Civilisation was eventually abandoned around 1900 BCE, and the reasons for its decline are still not fully understood.
