Rudolf II, Holy Roman Emperor (1552 - 1612). Rudolf II was Holy Roman Emperor, King of Hungary and Croatia, King of Bohemia and Archduke of Austria. He was a member of the House of Habsburg. Rudolf's legacy has traditionally been viewed in three ways: an ineffectual ruler whose mistakes led directly to the Thirty Years' War; a great and influential patron of Northern Mannerist art; and an intellectual devotee of occult arts and learning which helped seed what would be called the scientific revolution. Rudolf was born in Vienna on 18 July 1552. He was the eldest son and successor of Maximilian II, Holy Roman Emperor, King of Bohemia, and King of Hungary and Croatia; his mother was Maria of Spain, a daughter of Charles V and Isabella of Portugal. He was the elder brother of Matthias who was to succeed him as king of Bohemia and Holy Roman Emperor. Rudolf spent eight formative years, from age 11 to 19, in Spain, at the court of his maternal uncle Philip II, together with his younger brother Ernest, future governor of the Low Countries. After his return to Vienna, his father was concerned about Rudolf's aloof and stiff manner, typical of the more conservative Spanish court, rather than the more relaxed and open Austrian court; but his Spanish mother saw in him courtliness and refinement. In the years following his return to Vienna, Rudolf was created King of Hungary, King of Bohemia and King of the Romans when his father was still alive. Rudolf would remain for the rest of his life reserved, secretive, and largely a homebody who did not like to travel or even partake in the daily affairs of state. He was more intrigued by occult learning such as astrology and alchemy, which was mainstream in the Renaissance period, and had a wide variety of personal hobbies such as horses, clocks, collecting rarities, and being a patron of the arts. He suffered from periodic bouts of melancholy, which was common in the Habsburg line. These became worse with age, and were manifested by a withdrawal from the world and its affairs into his private interests. Like his near-contemporary, Elizabeth I of England, Rudolf dangled himself as a prize in a string of diplomatic negotiations for marriages, but never in fact married. During his periods of self-imposed isolation, Rudolf reportedly had affairs with his court chamberlain, Wolfgang von Rumpf, and a series of valets. One of these, Philip Lang, ruled him for years and was hated by those seeking favour with the emperor. In addition, Rudolf was known to have had a succession of affairs with women, some of whom claimed to have been impregnated by him. He had several illegitimate children with his mistress Catherina Strada. Their eldest son, Don Julius Caesar d'Austria, was likely born between 1584 and 1586 and received an education and opportunities for political and social prominence from his father. Rudolf condemned his son's act and suggested that he should be imprisoned for the rest of his life. However, Julius died in 1609 after showing signs of schizophrenia, refusing to bathe, and living in squalor; his death was apparently caused by an ulcer that ruptured. Many artworks commissioned by Rudolf are unusually erotic. The emperor was the subject of a whispering campaign by his enemies in his family and the Catholic Church in the years before he was deposed. Sexual allegations may well have formed a part of the campaign against him. Rudolf succeeded his father Maximiliam II on 12 October 1576. In 1583 he moved the court to Prague. Historians have traditionally blamed Rudolf's preoccupation with the arts, occult sciences, and other personal interests as the reason for the political disasters of his reign. More recently historians have re-evaluated this view and see his patronage of the arts and occult sciences as a triumph and key part of the Renaissance, while his political failures are seen as a legitimate attempt to create a unified Christian empire, which was undermined by the realities of religious, political and intellectual disintegrations of the time. Although raised in his uncle's Catholic court in Spain, Rudolf was tolerant of Protestantism and other religions including Judaism. He largely withdrew from Catholic observances, even in death denying last sacramental rites. He had little attachment to Protestants either, except as counter-weight to papal policies. He put his primary support behind conciliarists, irenicists and humanists.
