We talk about in other videos, the Middle Ages refers to that roughly 1,000 year period of time in Europe from the end of the Western Roman Empire in 476 until we get to about 1,000 years later with the emergence of the Renaissance and the Age of Exploration. And we associate it with knights in shining armor and their coat of chivalry, with kings in castles surrounded by moats. And we also associate it with the feudal system, which is how most of Europe was governed during the Middle Ages. Now, many of you are probably familiar with some of the key actors within the feudal system. At the top, you would have a king. Now, the king would rule over a kingdom. Now, this is not so easy to govern, especially during the Middle Ages, and the king might owe many people things, especially people who helped the king come to power, helped him depose the previous king or to conquer this land.
