The Middle Ages (or the Medieval times) were not limited to any one century. In fact, when we speak of the Middle Ages, we are generally referring to an entire millennium.
The Middle Ages are generally said to have started with the "fall" of the Western Roman Empire. This happened in 476 CE. The Middle Ages then lasted until the beginning of the Renaissance, in roughly 1500 CE.
Of course, this "medieval world" did not stay the same during all of this time. There were tremendous differences between the world of 500 CE and that of 1400 CE. However, both of these times are referred to as the "Middle Ages."
The Middle Ages, the so-called "medieval period" commenced with the collapse of the Western Roman Empire in 476 C.E. and ended with the fall of Constantinople in 1453 C.E. The medieval period can therefore be neatly sandwiched between the fall of the Western and Eastern Roman Empires.
The Middle Ages can further be classified into three sub-groups:
- The Early Middle Ages, (450 - 1050 C.E.) which commenced with the collapse of the Western Roman Empire through the period of Viking and Magyar Invasions.
- The High Middle Ages, 1050 - 1350 C.E.) marked by the Crusades, the rise of towns, and large population growth
- The Late Middle Ages, (1350-1453 C.E.) marked by the onset of the Black Death, and the collapse of the entire medieval culture.
it started in about 470 AD to 15th century
