A dynasty is a series of rulers from the same family or lineage, often maintaining power over a long period. These families typically pass down their leadership roles through generations, creating a sense of continuity and tradition. Famous examples include the Ming Dynasty in China and the Tudor Dynasty in England, both of which had significant impacts on their respective countries' cultures and histories. Dynasties can influence politics, economics, and social structures. They often establish laws and customs that shape the lives of their subjects. The rise and fall of dynasties can lead to major changes, such as the Roman Empire's transition from a republic to imperial rule, showcasing the power and legacy of dynastic rule.
