Emperor

The title of emperor was held by certain officials and heads of state in certain governments. It was usually, but not always, inherited. Sometimes successful warlords and conquerors created empires by declaring themselves emperor.

It is uncertain how, or even whether, an emperor's position and authority differed from that of a king. Usually, the title of emperor suggested someone who ruled over a far greater region or variety of cultures than those of a kingdom.
