History IS the lie commonly agreed on. I definately agree with Voltaire when saying this because history is based on each persons opinion, each persons knowledge and perspective of something. History may be interpreted in a way that differs completely from its truth. Some people believe that just because things and events are written in history books, they are 100% true. when really, they arent. History books are written from the perspective of some people and word it their way or to sometimes, their advantage. Ofcourse no country will publish a book about a tragic war that happened in it and its loss. Whether by not explaining the event well, or just not mentioning it, writers can change the way an event seems and may convince us that that is true, when sometimes, its a lie.
So yes, history is a lie and we might never know the real story behind events that occured in the past and are still happening.
