I want to know the answer to the following question:
What was the span of the Mature Harappan period?
All the background I'm provided with is that "This civilization collapsed at the start of the second millennium BCE and was later followed by the Iron Age Vedic Civilization, which extended over much of the Indo-Gangetic plain and which witnessed the rise of major polities known as the Mahajanapadas.". Is that enough to answer the question?
