Treaty of Rheinfelden
From Wikipedia, the free encyclopedia
The Treaty of Rheinfelden was concluded on June 1, 1283 in Rheinfelden. The then eleven-year-old Duke Rudolph II of Austria had to waive all his rights to the thrones of Austria and Styria to the benefit of his elder brother Albert I. The fact that Rudolph was never compensated induced his son John Parricida to murder Albert in 1308.
