India is one of the richest countries in the world in terms of history and heritage. Many great rulers have been born in our country in the history of the world. The list in this book covers the kings who ruled India and other countries from BC to modern India. The list may include some names who were not kings in the traditional sense, but who played important roles in their kingdoms.

There are many kings and kingdoms that the world has seen. So it is not possible to give a straight answer to the greatest king of all time as he has to face various situations and circumstances and even betrayals before the rise of his kingdom. But in my opinion the list of kings in this book are the greatest kings the world has ever seen.
