After his father died, Constantius became an Augustus. An Augustus was a high-ranking emperor. He shared the empire with his two brothers, Constantine II and Constans.

This division meant the empire was split into different parts. Constantius ruled the east, including Egypt, Greece, and Thrace. His reign was a very busy time for the Roman Empire.

Life as an emperor involved many hard jobs. Constantius spent much of his time fighting wars. In the east, he fought the Sasanian Empire. King Shapur II led the Sasanian armies against Rome.

Constantius had to defend important cities like Amida. He even built new walls and towers to keep them safe. He also built a new stronghold called Antinopolis. On the borders, he fought Germanic tribes like the Alamanni. He also campaigned against the Quadi and Sarmatians near the Danube River. These battles were constant and required much of his attention.

History shows that Constantius faced many internal struggles too. After his father died, many of his relatives were killed by the army. Some people blamed Constantius for this event. Later, a man named Magnentius took power in the west unfairly. This is called a usurpation. Constantius had to fight a civil war to take back control. He won a very large battle at Mursa Major in 351.

He won another victory at Mons Seleucus in 353. After these battles, Constantius became the sole ruler of the empire.

Constantius also made big changes to how people practiced religion. He promoted a belief called Arianism. He also banned the old pagan sacrifices.

He even made laws that affected Jewish people. He also dealt with his own family members as leaders. He made his cousin, Constantius Gallus, a Caesar to help rule the east. However, Constantius later had Gallus executed because of reports about his behavior. Finally, he promoted his other cousin, Julian, to the rank of Caesar in 355.

We can see how Constantius's life connects to the wider Roman world. His family's rule helped shape how the empire was divided. The wars he fought against Persia and Germanic tribes were part of a long history of border conflicts.

Even his death was part of a political story. He became ill with a fever in 360. He died in Mopsuestia on 3 November 361. Some say he named Julian as his successor before he passed away. His life shows how much work it took to lead such a huge empire.
