The Middle Ages is called so because it is the period of time between the fall of the Roman Empire in the 5th century and the beginning of the Renaissance in the 14th century.

This period is also known as the medieval period, and it is characterized by the development of feudalism, the rise of Christianity, and the dominance of monarchies in Europe. **

During the Middle Ages, people did not refer to that time period as the "Middle Ages."

The term "Middle Ages" was first coined in the 15th century by Renaissance scholars who viewed the period between the fall of the Roman Empire and their own time as a "middle" or intermediate period. **
