The Habsburg Dynasty was a powerful royal family that ruled over many parts of Europe for centuries. Originating in the 11th century, they became known for their strategic marriages, which helped them gain vast territories. Their influence peaked during the 16th and 17th centuries, when they controlled regions like Austria, Spain, and parts of Italy and the Netherlands. One of the most famous Habsburg rulers was Charles V, who was both the Holy Roman Emperor and King of Spain. The dynasty is also known for its distinctive physical trait, the Habsburg jaw, which resulted from generations of intermarriage. Their legacy continues to shape European history today.
