I will put this in different form. Let they are two-person say A and B.
A know the whole history of his ancestors and B don't know anything of his ancestors.
A will definitely feel pride about his ancestors and B will not have this opportunity.
Is Pride alone is enough? Then what we learn from the History. History alone dose not means War and capturing. It also shows how the human civilization evolved an how peoples lived and what they achieve on their period. I personally Feel with out history we will not have achieved the technology growth what we are presently enjoying. Take the invention of wheel in Mespotian Civilization (Currently IRAQ). Compared to other countries India is having an good history and that too Tamilnadu is having an good history. So we should really fell for that and salute our ancestors for the basement they have made for us to live an sophisticated life.
