The Habsburg Monarchy was a powerful European empire that lasted from the late Middle Ages until the early 20th century. It was ruled by the Habsburg family, who held various titles, including Holy Roman Emperors. The monarchy included diverse territories, such as Austria, Hungary, and parts of Italy and Spain, making it one of the largest empires in Europe. The Habsburgs were known for their strategic marriages, which expanded their influence and territory without constant warfare. The monarchy played a significant role in European politics, culture, and religion, particularly during the Renaissance and Reformation periods, until its dissolution after World War I.
