What is the importance of history?

those who do not learn from history are destined to repeat it.... Imagine if we did not learn from our and others mistakes and repeated the holocaust or the civil war again and lose thousands of lives because we did not pay attention to our history.
History is important as it covers a huge spectrum of human activities including arts- literature, architecture, politics, painting and many others.We have to consider our past to build our future because we learn from our past mistakes.We learn to improve by learning from past mistakes.Through history we learn about our culture,tradition and moral values.
