Three Migrations and Three Invasions

This book is about history of India. It is my sincere attempt to tell all the people of my country about us - who we all are and where we came from. Critical analyses of the three migrations - Hunters and Gatherers around 80000 years ago, Central Asian Pastoral population around 50000 years ago and Indo-Aryans around 6000 years ago, and, three invasions - King Alexander, Islamic and the British, that this country faced, is carried out, to clearly bring out the evolutionary process that this country was subjected to, since 80000 years ago. The partially interbred population from the three migrations, had given rise to great philosophies about God and life, that had influenced other religions of our world. Finally, this book analyzes and questions the implementation of the infamous Caste System, the enormous damage it had done to the Indian Society and the need to eradicate the same.
