Ancient history is the study of the written past from the beginning of recorded human history to the Early Middle Ages. The span of recorded history is roughly 5,000 years, with Cuneiform script, the oldest discovered form of coherent writing, from the protoliterate period around the 30th century BC. This is the beginning of history, as opposed to prehistory, according to the definition used by mosthistorians. From the big bang, the primeval swamp to the Indus Valley Civilization. There is a tendency to sometimes include the Indus Valley Civilization in prehistory, since technically prehistory includes everything that happened before the Word happened. However, technically again the Indus Valley Civilization did have a script, although it has not been decoded yet. So, it's generally included in Ancient History nowadays. For India, it begins from the Indus Valley Civilization (for which the date is a matter of hot debate, but historians have agreed to disagree on 3000BC) to just after the king Harsha Vardhana, which is around 700-800BC. The uniqueness of this book hence lies in the author's way of reconstructing the chapter under review by delving deep into the areas of the subject.
