William of Austria (c. 1370 – 15 July 1406), also known as William the Courteous was a scion of the House of Habsburg, Duke of Carinthia, Styria and Carniola.

Life

Born in Vienna, he was the oldest son of Duke Leopold the Just and his wife, Viridis Visconti.

At the age of 14, he was betrothed to Jadwiga, youngest daughter of King Louis I of Hungary, who was also king of Poland. This was one of the first attempts of the Habsburgs to extend their dominion by marrying heiresses, as Louis intended his elder daughter Mary and her fiancé Sigismund of Luxembourg to inherit Poland, while Jadwiga inherited Hungary.

When Louis died in 1382, Mary succeeded in Hungary. The Poles then rejected Mary and Sigismund, and instead chose Jadwiga as queen regnant. They also repudiated the betrothal to William.

In 1386, his father Leopold died, and William succeeded as head of the Leopoldian Line and ruler of the three duchies.

In 1401, William married another presumptive heiress, Joanna of Naples. She was Jadwiga's cousin, and also of Angevin descent. The marriage did not produce any offspring and William did not live to see his wife succeed her brother as Queen Joanna II.

In 1404, his first cousin Duke Albert the Patient died, leaving the lands of the Albertinian line of the Habsburgs to his seven-year-old son Albert the Magnanimous. William tried to take the Albertinian territories from the child Albert, but did not succeed before his death.

Death

William died in 1406 in Vienna. He is buried in the Dukes' Catacomb in Vienna's Cathedral of Saint Stephan.
