Why is studying the 20th century important?

History is an important part of human life because of the experience we gain by studying and learning from our mistakes. We can better ourselves by observing what worked in the past. We are able to take the ideas and run with them, changing ideas to make them suit our fast paced life and fix the mistakes made originally. We learn about our heritage and our own culture. It is important so that we don't allow ourselves to become Americanized or dominated by other countries. We are able to become our own individuals with a sense of our background.
