Answer:
History is the study of change over time, and it covers all aspects of human society. Political,
social, economic, scientific, technological, medical, cultural, intellectual, religious and military
developments are all part of history. Usually professional historians specialize in a particular aspect of
history, a specific time period, a certain approach to history or a specific geographic region. Historians know that the philosophy and methodology of history have changed over time and will keep changing. Many different interpretations of all historical topics exist. Historians must work to recognize the difference between facts and interpretations in their field.
