Frederick III (1415-1493), King of the Romans (informally King of Germany) from 1440 to 1493; Holy Roman Emperor (1452-1493), Duke of Styria, Carinthia and Carniola (1424), Archduke of Austria (1457), 1461
Frederick III (German: Friedrich; 21 September 1415 – 19 August 1493), was Holy Roman Emperor from 1452 until his death, the first emperor of the House of Habsburg. He was the penultimate emperor to be crowned by the Pope, and the last to be crowned in Rome. Prior to his imperial coronation, he was duke of the Inner Austrian lands of Styria, Carinthia and Carniola from 1424, and also acted as regent over the Duchy of Austria (as Frederick V) from 1439. He was elected and crowned King of Germany (as Frederick IV) in 1440. He was the longest-reigning German monarch when in 1493, after ruling his domains for more than 53 years, he was succeeded by his son Maximilian I. During his reign, Frederick concentrated on re-uniting the Habsburg "hereditary lands" of Austria and took a lesser interest in Imperial affairs. Nevertheless, by his dynastic entitlement to Hungary as well as by the Burgundian inheritance, he laid the foundations for the later Habsburg. Born at the Tyrolean residence of Innsbruck in 1415, Frederick was the eldest son of the Inner Austrian duke Ernest the Iron, a member of the Leopoldian line of the Habsburg dynasty, and his second wife Cymburgis of Masovia.
