History

History is an auxiliary science that involves the study of events that happened in the past. This can be the study of humanity's history, or anything else's history. History is constantly being re-written, as further studies about the past reveal new truths not previously realized.

A person who travels through time has the ability to change history, by altering past events and creating an alternate timeline.

Mr. Mergen blamed man's history for the conditions of the world. Because man continues to repeat the mistakes made by men in the past.
