History in a broad sense: the process of the development of the objective world movement can be divided into two aspects: natural history and human social history. The process of the occurrence and development of human society. History: the study of history, or historiography for short. Corresponding to the concept of history, history also has broad sense and narrow sense. History in a broad sense: all the sciences in the world can be called history. ("We only know a unique science, and that is the history science." -Marx and Engels) narrow sense history: the study of the development process of past movements in human society.

History provides people with experience, but it doesn't give people direct guidance. No one can get direct guidance from history, because history is always a thing of the past, and everything now can't completely repeat the past.

But history is the foundation of all disciplines, just like philosophy. We can't see which subject is divorced from history. Tracing back to the origin of these disciplines, we can find that many of them come from history. There was no politics, sociology or anthropology in ancient times. Everything has developed from history and philosophy. It is a summary of history. Even natural science can't get rid of its own history, because without inheritance, there would be no physics, chemistry, mathematics and so on. You can ask those who don't understand the role of history, and then you will know the usefulness of Pythagoras, Euler, lavoisier, Einstein, Newton, Darwin and Morgan.
