The History of Punjab is as old as the history of the Indian Civilization. The land of five rivers, this state was known as Panchal when the Aryans came to India in the third millennium BC. before that, the whole region of the Sindhu (Indus) and its tributaries were inhibited by the Harappans or the people of Copper age who constructed great cities in this region. Ropar in modern Punjab is a great example of this civilization. The Harappan culture declined suddenly between 1800-1700 BC and its end is as puzzling as its beginning. After the decline of the Harappans, Aryans from Central Asia ventured into this land and made this their home.
