Biography
Justina was a Roman empress in the fourth century CE, a time of religious conflict and imperial succession issues. Born around 340 CE, she was possibly connected to the Constantinian dynasty, which provided her with noble status and political ties within Roman elites. Her first marriage was to Magnentius, a rebel emperor who opposed the legitimate rule but was defeated and killed in 353 CE.
After Magnentius's death, Justina married Valentinian I, becoming his second wife after Marina Severa. They married around 370 CE, a union that was both politically beneficial and personally successful, resulting in four children, including the future emperor Valentinian II. Her daughter Galla later became empress by marrying Theodosius I. As Valentinian's wife, Justina became Augusta and stepmother to Gratian, Valentinian's son from his earlier marriage.
When Valentinian I died suddenly in 375 CE, Justina showed her political skill by ensuring her young son Valentinian II was made emperor, despite his young age. During her son's regency, she held significant influence over imperial policies, especially in religion. An Arian Christian, she supported Arian Christianity against the dominant Nicene creed, often clashing with Ambrose, the influential bishop of Milan. Her reign was marked by her challenge to the established church authority.
In the later part of her life, Justina faced civil war started by Magnus Maximus, who invaded Italy in 387 CE to extend his rule beyond Gaul and Britain. Threatened by this invasion, Justina decided to flee Italy with her children, including the young emperor Valentinian II, seeking safety in the Balkans. In Thessalonica, she secured vital military support from Eastern emperor Theodosius I by arranging for her daughter Galla to marry him. This marriage was key to defeating Magnus Maximus, although Justina died around 388 CE, before her son fully regained his imperial power.
Before Fame
Little is definitively known about Justina's early life, though her possible connection to the Constantinian dynasty suggests she was born into the Roman upper class during a time of big political and religious changes. The fourth century was marked by the acceptance and support of Christianity under Constantine I, followed by complex theological disputes among different Christian groups.
Her rise to imperial prominence began with her marriage to Magnentius, a military commander who declared himself emperor in 350 CE against Constantius II. This rebellion ultimately failed, but it gave Justina early exposure to imperial politics and the risky power struggles that marked the later Roman Empire.
