or Hapsburg dynasty
Royal German family, one of the chief dynasties of Europe from the 15th to the 20th century.
As dukes, archdukes, and emperors, the Habsburgs ruled Austria from 1282 until 1918. They also controlled Hungary and Bohemia (15261918) and ruled Spain and the Spanish empire for almost two centuries (150406, 15161700). One of the earliest Habsburgs to rise to great power was Rudolf I , who became German king in 1273. Frederick IV, the Habsburg king of Germany, was crowned Holy Roman emperor as Frederick III in 1452, and Habsburgs continued to hold that title until 1806. Frederick's son Maximilian I acquired the Netherlands, Luxembourg, and Burgundy through marriage. The zenith of Habsburg power came in the 16th century under the emperor Charles V .
