The "Four Lords" refers to a group of four noble figures in the context of the Feudal System in medieval Europe. These lords typically held significant power and land, serving as vassals to a higher-ranking monarch. Each lord managed their own territory, providing protection and governance to the peasants and serfs living on their land. In some cultures, the term "Four Lords" can also relate to specific mythological or religious figures. For example, in Chinese mythology, the Four Lords are often associated with the four cardinal directions and elements, symbolizing balance and harmony in the universe.
