Constantine II (Flavius Claudius Constantinus, 316–340 CE) was the eldest son of Constantine the Great and a member of the Constantinian dynasty. Proclaimed Caesar in 317 while still a child, he was trained for imperial rule and given command responsibilities in the western provinces. After the death of his father in 337, Constantine II became Augustus and ruled jointly with his brothers Constantius II and Constans, dividing the empire among them. Constantine II initially controlled territories including Gaul, Britannia, and Hispania. Disputes with his younger brother Constans over territorial authority led him to invade Italy in 340, but he was defeated and killed in an ambush near Aquileia, bringing his brief reign to an end.
