Which term refers to a succession of rulers from the same family?

The term that refers to a succession of rulers from the same family is "dynasty." Dynasties are often characterized by the establishment of a ruling lineage where political power is passed down through generations, typically within a family, such as in the case of royal families. Historical examples of dynasties include the Romanov dynasty in Russia and the Ming dynasty in China, where each ruler within the dynasty maintained authority based on their family ties.

In contrast, an oligarchy refers to a form of government where power resides in the hands of a small group of people, typically distinguished by wealth or noble birth. Monarchy, while it may connect to the idea of rulers, encompasses a broader definition that includes both hereditary and elected kings or queens, rather than specifically indicating a succession of rulers solely from one family line. Theocracy describes a system of governance where priests or religious leaders control the government, claiming authority based on religious law, rather than a familial succession. Thus, "dynasty" accurately captures the concept of succession through family lineage.
