When a line of rulers who belong to the same family and pass control from one generation to another?

A line of rulers from the same family that passes control from one generation to another is known as a dynasty. Dynasties often establish a legacy through hereditary succession, where power is typically passed down to the eldest son or designated heir. This system can lead to stability and continuity within a state, but it can also result in conflicts over succession and varying degrees of governance effectiveness. Examples include the Ming Dynasty in China and the House of Windsor in the United Kingdom.
