European monarchs are the kings, queens, princes, and princesses who rule or have ruled various countries in Europe. Many of these monarchies have deep historical roots, with some dating back over a thousand years. Monarchs often serve as symbols of national unity and continuity, representing their countries in ceremonial roles and diplomatic functions. While some European monarchies, like those in United Kingdom and Sweden, are constitutional, meaning their powers are limited by law, others, such as Vatican City, have absolute monarchs. The roles and influence of these monarchs can vary significantly, reflecting the diverse political landscapes across Europe.
