text: is a dynasty the same as a monarchy? they seem so similar, only they have different names and belong to different cultures. thanks for your help. a monarchy is a form of government- with a king or emperor- some kind of inherit-able leadership.  a dynasty can happen in a monarchy. it is a period of time. it's when one family rules a nation for a long period of time. usually, a dyansty (a long period of one family's holding the throne)has a definite influence on the nation's culture, art, etc.
