A dynasty is a sequence of rulers from the same family or lineage, often maintaining power over a long period. Dynasties are commonly associated with monarchies, where kings and queens inherit their positions. This system can lead to stability or conflict, depending on how power is passed down and the relationships within the family. Throughout history, many notable dynasties have shaped nations, such as the Ming Dynasty in China and the Tudor Dynasty in England. These families often influence politics, culture, and society, leaving lasting legacies that can be seen in modern times.
