Hungarian royalty refers to the historical monarchy that ruled over the Kingdom of Hungary from the Middle Ages until the early 20th century. The most notable royal house was the Árpád dynasty, which established the kingdom in the 9th century. Over the centuries, Hungary was ruled by various dynasties, including the Angevin and Habsburg families, who played significant roles in European politics. The last king of Hungary was Charles IV, who reigned during the tumultuous period of World War I. Following the war, Hungary became a republic, and the monarchy was officially abolished in 1946. Today, the legacy of Hungarian royalty is preserved in historical sites, traditions, and cultural heritage.
