The term "Habsburg" refers to a powerful European royal family that played a significant role in history from the late Middle Ages to the early 20th century. The Habsburgs ruled over vast territories, including parts of modern-day Austria, Hungary, and Spain. Their influence extended through strategic marriages, which helped them acquire more lands and titles without the need for warfare. One of the most famous Habsburg rulers was Emperor Franz Joseph I, who led the Austro-Hungarian Empire during a time of great change. The family's legacy is marked by their contributions to art, culture, and politics, making them a key part of European history.
