Joseph I (Joseph Jacob Ignaz Johann Anton Eustachius; 26 July 1678 – 17 April 1711) was Holy Roman Emperor and ruler of the Habsburg monarchy from 1705 until his death in 1711. He was the eldest son of Leopold I, Holy Roman Emperor from his third wife, Eleonor Magdalene of Neuburg. Joseph was crowned King of Hungary at the age of nine in 1687 and was elected King of the Romans at the age of eleven in 1690. He succeeded to the thrones of Bohemia and the Holy Roman Empire when his father died.
Joseph continued the War of the Spanish Succession, begun by his father against Louis XIV of France, in an attempt to make his younger brother Charles (later Emperor Charles VI) King of Spain. In the process, however, owing to the victories won by his military commander, Prince Eugene of Savoy, he did succeed in establishing Austrian hegemony over Italy. Joseph also had to contend with a protracted revolt in Hungary, fomented by Louis XIV. Neither conflict was resolved until the Treaty of Utrecht, after his death.
His motto was Amore et Timore (Latin for "Through Love and Fear"). Like his father and grandfather, he was a composer.
Early life

Born in Vienna, Joseph was educated strictly by Charles Theodore, Prince of Salm, and became a good linguist. Perhaps due to the influence of his formerly Protestant tutor he was a less devout Catholic than his parents and other relatives and developed into an adherent of the early Age of Enlightenment. He had two great enthusiasms: music and hunting.

Prior to his ascension, Joseph had surrounded himself with reform-hungry advisors and the young court of Vienna was ambitious in the elaboration of innovative plans. He was described as a "forward-looking ruler".
In Hungary, Joseph had inherited the kuruc rebellion from his father Leopold I: once again, nobles in Transylvania (Siebenbürgen) had risen against Habsburg rule, even advancing for a time as far as Vienna. Although Joseph was compelled to take military action, he refrained—unlike his predecessors—from seeking to teach his subjects a lesson by executing the leaders. Instead, he agreed to a compromise peace, which in the long term facilitated the integration of Hungary into the Habsburg domains.
Death

During the smallpox epidemic of 1711, which killed Louis, Grand Dauphin and three siblings of the future Emperor Francis I, Joseph became infected. He died on 17 April in the Hofburg palace. He had previously promised his wife to stop having affairs, should he survive.
The Emperor was buried in the Imperial Crypt, resting place of the majority of the Habsburgs. His funeral took place on 20 April, in tomb no. 35 in Karl's Vault. His tomb was designed by Johann Lukas von Hildebrandt, decorated with pictures of various battles from the War of Spanish Succession. Josefstadt (the eighth district of Vienna) is named for Joseph.
Marriage and lack of heirs
On 24 February 1699, he married Wilhelmine Amalia of Brunswick-Lüneburg in Vienna. They had three children and their only son died of hydrocephalus before his first birthday. Joseph had a passion for love affairs (none of which resulted in illegitimate children) and he caught a sexually transmittable disease, probably syphilis, which he passed on to his wife while they were trying to produce a new heir. This incident rendered her sterile.
