The head of state in a monarchy is typically the monarch, such as a king or queen. They embody the state's tradition and serve as a symbol of national unity. While the monarch's powers vary significantly across different systems—ranging from ceremonial roles to those with substantial authority—their presence often represents the continuity of the state. In constitutional monarchies, such as the United Kingdom, the monarch's role is mostly symbolic, with legislative powers exercised by elected representatives. In absolute monarchies, however, the monarch may wield significant political power.
