Can somebody give me a definition of national history?

Before we can start our lessons on the history of the Middle East, we are assigned to define some 'general' historical words.

The fact that national history just describes the history of a nation seems too simplistic to me. Has anybody got ideas, personal opinions, on what does and what does not fit in national history?


Ps - Im not trying to get you to go my homework But the lessons we are enrolled in are more discussions as well as definitions etc, so I couldnt think of a better place to discuss but tc
