1. Disappearance of the Indus Valley Civilization
The Indus valley civilisation is perhaps India’s most ancient mystery. There are many unanswered questions about this great civilisation that was larger than the ancient Egyptian and Mesopotamian civilisations combined. The secrets behind the identity of the people who created it and their puzzling 4000-year-old Indus pictographic script are yet to be discovered. Also, perhaps the most bewildering fact about this civilisation is that all its major sites went into sudden decline and disappeared more or less simultaneously. There are several theories about why this happened but none of them have been very conclusive.
