The Mayerling Incident is the series of events leading to the apparent murder–suicide of Crown Prince Rudolf of Austria (21 August 1858 – 30 January 1889) and his lover Baroness Mary Vetsera (19 March 1871 – 30 January 1889). Rudolf was the only son of Emperor Franz Josef I of Austria and Empress Elisabeth, and heir to the throne of the Austro-Hungarian Empire. Rudolf's mistress was the daughter of Baron Albin Vetsera, a diplomat at the Austrian court. The bodies of the 30-year-old Archduke and the 17-year-old baroness were discovered in the Imperial hunting lodge at Mayerling in the Vienna Woods, fifteen miles southwest of the capital, on the morning of 30 January 1889.
