Scandinavian kings historically ruled over the regions of Denmark, Norway, and Sweden. These monarchs played significant roles in shaping the political landscape of Northern Europe, often engaging in alliances, wars, and trade. The Viking Age, from the late 8th to the early 11th century, saw many Scandinavian kings expand their territories and influence through exploration and conquest. In modern times, Scandinavian kings are largely ceremonial figures. The current monarchs, such as King Harald V of Norway, Queen Margrethe II of Denmark, and King Carl XVI Gustaf of Sweden, represent their countries at official events and promote national unity. Their roles are primarily symbolic, with real political power resting in elected governments.
