Historian Thomas A. Brady Jr. credited Frederick with leaving a credible claim on the imperial title and a secure grip on the Austrian lands, now organized as a single state, for his son. This imperial revival (as well as the rise of the territorial state) began under the reign of Frederick.

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. According to the 1379
Treaty of Neuberg, the Leopoldinian branch ruled over the duchies of Styria, Carinthia and Carniola, or what was referred to as Inner Austria. Only three of Frederick's eight siblings survived childhood: his younger brother
Albert (later to be Albert VI, archduke of Austria), and his sisters

(later the electress of Saxony) and
Catherine. In 1424, nine-year-old Frederick's father died, making Frederick the duke of Inner Austria, as Frederick V, with his uncle, Duke
Frederick IV of Tyrol, acting as regent.
From 1431, Frederick tried to obtain majority (to be declared "of age", and thus allowed to rule) but for several years was denied by his relatives. Finally, in 1435,
Albert V, duke of Austria (later Albert II, the king of Germany), awarded him the rule over his Inner Austrian heritage. Almost from the beginning, Frederick's younger brother Albert asserted his rights as a co-ruler, as the beginning of a long rivalry. Already in these years, Frederick had begun to use the symbolic
A.E.I.O.U. signature as a kind of
motto with various meanings. In 1436 he made a pilgrimage to the

Order of the Holy Sepulchre, which earned him great reputation.
Upon the death of his uncle Duke Frederick IV in 1439, Frederick took over the regency of Tyrol and
Further Austria for the duke's heir
Sigismund. Again he had to ward off the claims raised by his brother Albert VI; he prevailed by the support of the Tyrolean aristocracy. Likewise he acted as regent for his nephew
Ladislaus the Posthumous, son of late King Albert II and his consort

Albertinian Line (Further Austria) was still viewed with suspicion.
As a cousin of late King Albert II, Frederick became a candidate for the
1440 imperial election The imperial election of 1440 was an imperial election held to select the emperor of the Holy Roman Empire. It took place in Frankfurt on February 2.

This coronation took place on the morning of 16 March, in spite of the protests of the Milanese ambassadors, and in the afternoon Frederick and Eleanor were married by the pope. Finally, on 19 March, Frederick and Eleanor were anointed in
St Peter's Basilica by the Vice-Chancellor of the Holy Roman Church, Cardinal
Francesco Condulmer, and Frederick was then crowned with the
Imperial Crown by the pope. Frederick was the last Holy Roman Emperor to be crowned in Rome. His great-grandson
Charles V was the last emperor to be crowned, but this was done in
Bologna.
Personality

Frederick's style of rulership was marked by hesitation and a sluggish pace of decision making. The Italian humanist Enea Silvio Piccolomini, later
Pope Pius II, who at one time worked at Frederick's court, described the Emperor as a person who wanted to conquer the world while remaining seated. Although this was regarded as a character flaw in older academic research, his delaying tactics are now viewed as a means of coping with political challenges in far-flung territorial possessions. Frederick is credited with having the ability to sit out difficult political situations patiently.
[''Heinz-Dieter Heimann: Die Habsburger. Dynastie und Kaiserreiche. . pp.38-45]
According to contemporary accounts, Frederick had difficulties developing emotional closeness to other persons, including his children and wife
Eleanor (Unlike his brother Albert and his son Maximilian, Frederick maintained a reserved lifestyle. Although he was willing to appear in social events like festivals and tournaments, he disliked lavish feasts. Later he became horrified when his son, still in early teen years, displayed a tendency towards wine, feasts and women.). As Frederick was rather distant to his family, Eleanor had a great influence on the raising and education of Frederick's children, and she therefore played an important role in the House of Habsburg's rise to prominence. Despite the fact that their marriage had been unhappy, when Eleanor died the Emperor was affected by her loss and remained widowed for the rest of his long life.

Emperor
Frederick's political initiatives were hardly bold, but they were still successful. Frederick III was crowned Holy Roman Emperor in 1452, the first since the death of Emperor Sigismund. His ascension to the role of Emperor came with the stipulation that should the previous queen give birth to a male heir, Frederick would become his guardian. When the queen gave birth to Ladislaus the Posthumous, as according to the stipulations, Frederick took on his guardianship. This led to conflicts between Frederick and other members of the royal family and nobility. His first major opponent was his brother Albert VI, who challenged his rule. He did not manage to win a single conflict on the battlefield against him, and thus resorted to more subtle means. He held his second cousin once removed Ladislaus the Posthumous, the ruler of the Archduchy of Austria

, Hungary and Bohemia, (born in 1440) as a prisoner and attempted to extend his guardianship over him in perpetuity to maintain his control over Lower Austria. Ladislaus was freed in 1452 by the Lower Austrian estates. He acted similarly towards his first cousin Sigismund of the Tyrolian line of the Habsburg family.
Ultimately, Frederick prevailed in all those conflicts by outliving his opponents and sometimes inheriting their lands, as was the case with Ladislaus, from whom he gained Lower Austria in 1457, and with his brother Albert VI, whom he succeeded in Upper Austria. In 1462, his brother Albert raised an insurrection against him in Vienna and the emperor was besieged in his residence by rebellious subjects. In this war between the brothers, Frederick received support from the King of Bohemia, George of Poděbrady. These conflicts forced him into an anachronistic itinerant existence, as he had to move his court between various places through the years, residing in Graz

, Linz and . owes him its castle and the "New Monastery". In 1469 Friedrich founded the Order of St. George, which still exists today, whereby the first investiture in the Lateran Basilica in Rome was carried out by him and Pope Paul II.
Mary soon made her choice among the many suitors for her hand by selecting Archduke Maximilian of Austria, the future Holy Roman Emperor Maximilian I, who became her co-ruler. With the inheritance of Burgundy, the House of Habsburg began to rise to predominance in Europe. This gave rise to the saying "Let others wage wars, but you, happy Austria, shall marry", which became a motto of the dynasty.
Frederick secured in 1486 the succession of the son in his own lifetime. On 16 February 1486 Maximilian was unanimously elected Roman-German king at the Frankfurt Reichstag by the six electors present. The Elector of Bohemia was not invited because the Bohemian spa law might have been claimed by the Hungarian King Corvinus. There are still discussions regarding whether Frederick actively provided the initiative for his son's election or not. As Frederick's only surviving male heir though, Maximilian was a natural choice for Frederick and the Estates to counter Hungary's ambitions. On the occasion of the election of Maximilian, a ten-year land peace was decided. In order to safeguard the peace of the land and against the expansive territorial policy of the Wittelsbachs, numerous affected empire-related states of Swabia joined in 1488 on Frederick's initiative for the Swabian League. After the royal election Frederick accompanied his son to Aachen, where Maximilian was crowned on 9 April 1486. There seemed to be tensions between father and son due to differences in personalities and leadership styles. But Frederick saw Maximilian's values in negotiating with the Estates, thus even though he was wary of infringments on his imperial power, Maximilian quickly became an essential partner in imperial politics.
In 1487, his daughter Kunigunde Kunigunde, Kunigunda, or Cunigunde, is a European female name of German origin derived from "kuni" (clan, family) and "gund" (war). In Polish this is sometimes Kunegunda or Kinga. People with such names include:

, Frederick withdrew his consent. On 2 January 1487, however, before Frederick's change of heart could be communicated to his daughter, Kunigunde married Albert. A war was prevented only through the mediation of the Emperor's son, Maximilian.
In some smaller matters, Frederick was quite successful: in 1469 he managed to establish bishoprics in Vienna and , a step that no previous Duke of Austria had been able to achieve.

Frederick decided to invade, but his army never got far, as he was no general. From Mantua, Pius II (who was also Frederick's former secretary) urged the Emperor to leave Mathias alone. Hungary, he proclaimed, "is the shield of all Christendom under cover of which we have hitherto been safe. ..If the road is thus opened to the barbarians, destruction will break in over all and the consequences of such a disaster will be imputed by God to its authors."

Frederick's personal motto was the mysterious string A.E.I.O.U., which he imprinted on all his belongings. He never explained its meaning, leading to many different interpretations being presented, although it has been claimed that shortly before his death he said it stands for ' or ' ("All the world is subject to Austria"). It may well symbolise his own understanding of the historical importance and meaning of his rule and of the early gaining of the Imperial title.
Frederick had been very careful regarding the reform movement in the empire. For most of his reign, he considered reform as a threat to his imperial prerogatives. He avoided direct confrontation, which might lead to humiliation if the princes refused to give way. After 1440, the reform of the Empire and Church was sustained and led by local and regional powers, particularly the territorial princes. In his last years, however, there was more pressure on him taking action from a higher level. Berthold von Henneberg, the Archbishop of Mainz, who spoke on behalf of reform-minded princes (who wanted to reform the Empire without strengthening the imperial hand), capitalized on Frederick's desire to secure the imperial election for Maximilian. Thus in his last years, he presided over the initial phase of Imperial Reform, which would mainly unfold under his son Maximilian. Maximilian himself was more open to reform, although naturally he also wanted to preserve and enhance imperial prerogatives. After Frederick retired to Linz in 1488, as a compromise, Maximilian acted as mediator between the princes and his father. When he attained sole rule after Frederick's death, he would continued this policy of brokerage, acting as the impartial judge between options suggested by the princes.
Patronage of the arts
Frederick was an important and powerful patron of music, with a "preference for importing Western talent". This, combined with the efforts by non-coủrtly institutions like the Cathedral at Trent, would contribute to the flourishing of music under Maximilian I.
The 110 books he collected form the core collection of the later ''Bibliotheca Regia'', that was the predecessor of the later Imperial Librrary and the current Austrian National Library (''Österreichische Nationalbibliothek'').
Legacy
German historians tend to be more critical of Frederick than Austrian ones. Austrian historian Adam Wandruszka opines that while he was not an impressive emperor, Frederick III was effective in defending and expanding his family's dynastic interests. Wandruszka calls him the "true founder of the Habsburg imperial position". German historians Paul-Joachim Heinig (author of ''Kaiser Friedrich III. (1440–1493). Hof, Regierung und Politik'', Böhlau, 1997) writes that it would be unfair to say that Maximilan stood on the shoulders of a giant, yet nevertheless Frederick provided the shoulders without which Maximilian could not have become a giant himself.
Frederick was a great benefactor to the Jews – his enemies described him as "more of a Jew than a Holy Roman Emperor". He favoured such Jewish scholars like , who was the teacher of the Hebraist Johann Reuchlin. His empress Eleanor also favoured Jews. For unknown reasons, their son Maximilian developed a dislike for the Jews as a child though, to the horror of both parents.
His own relationship with the Jews evolved over the years though. Schattner-Rieser opines that the foundation of Modern Judaism, arising in the eras of Frederick and Maximilian, was "embedded in the principles of humanism".
Marriage and children
Frederick had five children from his marriage with Eleanor of Portugal:
* Christoph (1455–1456)
* Maximilian (1459–1519), Holy Roman Emperor, married
# 1477 Mary of Burgundy (1457–1482), daughter of Duke of Burgundy Charles the Bold

Death
In his last years Friedrich remained in the region on the Danube, in Vienna and in Linz. In 1492 he was elected Knight of the Order of the Golden Fleece. Since February 1493, Frederick's health deteriorated increasingly. In the Lent of 1493, Friedrich's personal physicians diagnosed Kaiser in the left leg as a symptom, usually referred to as age-burning, in the research literature, which according to current medical terminology is considered to be the result of arteriosclerosis. On 8 June 1493 he was amputated under the direction of the surgeon Hans Seyff in the Linz castle of the affected area of the leg. This leg amputation is considered one of the most famous and best-documented surgical procedures of the entire Middle Ages. Although Frederick initially survived the procedure well, he died on 19 August 1493 in Linz at the age of 77. The contemporaries cited as the cause of death the consequences of leg amputation, senility or rapid diarrhea caused by melon consumption. His bowels were probably buried separately on 24 August 1493 in the Linz parish church. The arrival of Turks in Carinthia and the Krain delayed the arrival of Maximilian and with it the funeral service. On 6 and 7 December 1493, the funeral took place in St. Stephen's Cathedral.
His grave, built by Nikolaus Gerhaert von Leyden, in St. Stephen's Cathedral, Vienna, is one of the most important works of sculptural art of the Late Middle Ages. (His amputated leg was buried with him.) The heavily adorned tomb was not completed until 1513, two decades after Frederick's death, and has survived in its original condition.[Rudolf J. Meyer: ''Königs- und Kaiserbegräbnisse im Spätmittelalter. Von Rudolf von Habsburg bis zu Friedrich III.'' Köln 2000, pp. 186–188.]
