India's history and culture is dynamic, spanning back to the beginning of human civilization. It begins with a mysterious culture along the Indus River and in farming communities in the southern lands of India. The history of India is punctuated by constant integration of migrating people with the diverse cultures that surround India. Available evidence suggests that the use of iron, copper and other metals was widely prevalent in the Indian sub-continent at a fairly early period, which is indicative of the progress that this part of the world had made. By the end of the fourth millennium BC, India had emerged as a region of highly developed civilization.
The History of India begins with the birth of the Indus Valley Civilization, more precisely known as Harappan Civilization. It flourished around 2,500 BC, in the western part of South Asia, what today is Pakistan and Western India. The Indus Valley was home to the largest of the four ancient urban civilizations of Egypt, Mesopotamia, India and China. Nothing was known about this civilization till 1920s when the Archaeological Department of India carried out excavations in the Indus valley wherein the ruins of the two old cities, viz. Mohenjodaro and Harappa were unearthed. The ruins of buildings and other things like household articles, weapons of war, gold and silver ornaments, seals, toys, pottery wares, etc., show that some four to five thousand years ago a highly developed Civilization flourished in this region.
