What is definition of dynasty?

A dynasty is a sequence of hereditary rulers from a single family or line of descent. It is a series of leaders of a country or kingdom belonging to the same family who maintain power and influence over a prolonged period of time. Typically, the dynasty's authority and power are passed down through generations via primogeniture, which means that the eldest son receives the throne upon his father's death. Dynasties have been a prominent feature of many countries throughout history, including in China, Persia, Egypt, and Europe.
