On 16 Mar 1278 William Jülich IV Count Jülich (age 68) and his son William Jülich (age 38) were killed. He and his two sons William and Roland (his natural son), had entered the town of Aachen to collect taxes for King Rudolph I of Germany (age 59). There was a riot and William and his sons were killed. The city of Aachen was later ordered to pay a high compensation to William's widow Richardis (age 63) as compensation for his murder.
