Why has the field of world history been growing?

The term "World History" is a bit of a misnomer.  Certainly, as other posts have indicated, its important to consider the history of other cultures and countries; doing so can only help our international situation today, but this consideration must be done in relation to one's own. Done properly, a profounder understanding of different cultures through time can occur. It is not to imply that one particular history is "true;" what it suggests is the ability of the student or scholar to appreciate all aspects of the time, place, and culture when events occurred. "World History" then, would be the understanding of events, or causes and effects, from multiple viewpoints.  But to have a viewpoint, one must start with one's own.

Studying the "History of the World" may be tacitly suggesting the abandonment of one's own cultural perspective in favor of another; however, to understand fully why we are where we are, inquiry must be made into causes and effects with a minimum of political correctness. The study of any history should concern itself with facts.  It should seek to establish what was true.
