We study history to learn from it. If we study history and decide to learn from the mistakes of the past we can make sure we don't make the same mistakes in the future. History has made almost every mistake possible and we have the choice to listen to it or not. If we listen to history and not twist the facts we are more likely to succeed in the future. We can see what went wrong and apply it to our lives. We make mistakes in our lives and we learn from them. We should do the same with history.
