The Habsburg Family was a prominent European royal house that played a significant role in the history of Austria and Spain. Originating in the 11th century, they expanded their influence through strategic marriages and territorial acquisitions, eventually ruling over vast regions in Europe. The family is best known for its connection to the Holy Roman Empire, where many Habsburgs served as emperors. Their reign included notable figures like Charles V and Maria Theresa, and they were instrumental in shaping European politics until the early 20th century, when their power diminished after World War I.
