The division changed once more in 350 when Constans was killed in battle by forces loyal to the usurper Magnentius. Until this time, Constantius was preoccupied with fighting the Sassanid Empire, and he was forced to elevate his cousin Gallus to Caesar of the East to assist him, while he turned his attention to this usurper. Constantius eventually met and crushed Magnentius in the Battle of Mursa Major, one of the bloodiest battles in Roman history, in 351. Magnentius committed suicide in 353, and Constantius soon after put his cousin Gallus to death. However, he still could not handle the military affairs of both the Eastern and German frontiers by himself, so in 355 he elevated his last remaining relative, Julian, to the rank of Caesar.
