Treaty of Schonbrunn

14 October 1809

Despite the disasters of the 1809 Campaign on the Danube, Austria's Emperor Francis I was not prepared to sign a peace treaty with France.

In the end, an increasingly impatient Napoleon Bonaparte issued an ultimatum to Francis leaving him in no doubt that the French emperor was prepared to go to war again unless there was official peace.

The Treaty of Schonbrunn saw Austria give up lands to Bavaria, the Duchy of Warsaw and Russia. She also ceded much of the Adriatic coastline to France.

All up, the treaty took 3.5 million people from Austria, land-locked her without access to Adriatic ports and left her facing a 75-million franc war debt to France.
