Alexander was forced to face his German enemies in the early months of 235.

Alexander was thus assassinated together with his mother in a mutiny of the Legio XXII Primigenia at Moguntiacum (Mainz) while at a meeting with his generals. These assassinations secured the throne for Maximinus. He died after a rule of 13 years.
