The House of Schleswig is a historical royal family that originated in the region of Schleswig, which is now part of modern-day Denmark and Germany. This house played a significant role in the politics of Northern Europe, particularly during the Middle Ages and the early modern period. Members of the house held various titles, including dukes and kings, and were involved in numerous conflicts and alliances. One of the most notable branches of the House of Schleswig is the House of Schleswig-Holstein, which emerged from the division of the original house. This branch was influential in the 19th century, especially during the Danish Wars, which involved disputes over territory and sovereignty in the region. The legacy of the house continues to be studied in the context of European history.
