Constantine I, also known as Constantine the Great, was a Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity. He played a pivotal role in elevating the status of Christianity in Rome, decriminalizing Christian practice and ceasing Christian persecution in a period referred to as the Constantinian shift. This initiated the Christianization of the Roman Empire. Constantine is associated with the religiopolitical ideology known as Caesaropapism, which epitomizes the unity of church and state. He founded the city of Constantinople and made it the capital of the Empire, which remained so for over a millennium.
The Tetrarchy was the system instituted by Roman emperor Diocletian in 293 AD to govern the ancient Roman Empire by dividing it between two emperors, the augusti, and their junior colleagues and designated successors, the caesares.
The 320s decade ran from January 1, 320, to December 31, 329.
Year 326 (CCCXXVI) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantinus and Constantinus. The denomination 326 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Flavius Valerius Constantius, also called Constantius I, was a Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname "Chlorus" was first popularized by Byzantine-era historians and not used during the emperor's lifetime.
Maximian, nicknamed Herculius, was Roman emperor from 286 to 305. He was Caesar from 285 to 286, then Augustus from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refortifying the frontier.
Flavia Julia Helena, also known as Helena of Constantinople and in Christianity as Saint Helena, was an Augusta of the Roman Empire and mother of Emperor Constantine the Great. She was born in the lower classes traditionally in the city of Drepanon, Bithynia, in Asia Minor, which was renamed Helenopolis in her honor, although several locations have been proposed for her birthplace and origin.
Flavius Julius Crispus was the eldest son of the Roman emperor Constantine I, as well as his junior colleague (caesar) from March 317 until his execution by his father in 326. The grandson of the augustus Constantius I, Crispus was the elder half-brother of the future augustus Constantine II and became co-caesar with him and with his cousin Licinius II at Serdica, part of the settlement ending the Cibalensean War between Constantine and his father's rival Licinius I. Crispus ruled from Augusta Treverorum (Trier) in Roman Gaul between 318 and 323 and defeated the navy of Licinius I at the Battle of the Hellespont in 324, which with the land Battle of Chrysopolis won by Constantine forced the resignation of Licinius and his son, leaving Constantine the sole augustus and the Constantinian dynasty in control of the entire empire. It is unclear what the legal status of the relationship Crispus's mother Minervina had with Constantine was; Crispus may have been an illegitimate son.
Flavia Maximiana Theodora was a Roman empress as the wife of Constantius Chlorus.
Flavia Maxima Fausta Augusta was a Roman empress. She was the daughter of Maximian and wife of Constantine the Great, who had her executed and excluded from all official accounts for unknown reasons. Historians Zosimus and Zonaras reported that she was executed for adultery with her stepson, Crispus.

Eutropia was a Roman empress of Syrian origin, the wife of Emperor Maximian.
Minervina was either the first wife or a concubine of Constantine I, and the mother of his eldest son Crispus.
Flavia Valeria Constantina, later known as Saint Constance, was the eldest daughter of Roman emperor Constantine the Great and his second wife Fausta, daughter of Emperor Maximian. Constantina may have received the title of Augusta from her father, and is venerated as a saint, having developed a medieval legend wildly at variance with what is known of her actual character.

The Constantinian dynasty is an informal name for the ruling family of the Roman Empire from Constantius Chlorus to the death of Julian in 363. It is named after its most famous member, Constantine the Great, who became the sole ruler of the empire in 324. The dynasty is also called Neo-Flavian because every Constantinian emperor bore the name Flavius, similarly to the rulers of the first Flavian dynasty in the 1st century.

Claudia was the purported mother of Roman emperor Constantius Chlorus according to ancient sources. These sources claim her to be a relative of Roman emperors Claudius Gothicus and Quintillus, a claim modern historians tend to view with suspicion.
