Diocletian (#89)

Background

Diocles was born in Dalmatia around the year 244. Diocles came from a family of low status. Little is known about the first forty years of Diocletian's life, though many suspect he held a military rank of some sort. In January of 284, the brothers Numerian and Carinus took control over the Roman Empire from their father. Unfortunately, Numerian died later in that year. Numerian, at the time of his death, was coming back from combat in Persia. When he died, his army voted on who should be succeed him as Emperor, and Diocles was chosen. After being chosen as Emperor, Diocles changed his name to Diocletianus, making his full name Gaius Aurelius Valerius Diocletianus. Toady, we know him as Diocletian.

Gaining Power

After Numerian's army had named Diocletian as emperor, Carinus was not to happy. To Carinus, Diocletian was a usurper opposing Carinus's rule, so Carinus decided to meet Diocletian in battle. Although Carinus had a stronger army and he had control over the Roman Senate, he was unpopular. Carinus and Numerian were the sons of the unpopular Emperor Carus, and neither the sons nor the father were too popular with the people. Diocletian and Carinus met in battle at the Battle of Margus, during which most of Carinus's generals defected to Diocletian. When Diocletian won the battle, both the western and eastern armies accepted Diocletian as the Augustus, or ruler.

Dividing Power

When Diocletian came to power, Rome was filled with problems. In the East, Rome was on the brink of war with Persia and the west faced constant threat from barbarian tribes. On top of that, the entire empire seemed to be on the brink of revolt. Diocletian decided that the job of Emperor was too big for one person, so Diocletian named Maximian as co-ruler of the Roman Empire in 285. Diocletian decided to rule over the East, because that part of the Empire was the more stable of the two. Maximian was assigned the Western Roman Empire. It was this division that divided the empire in two and allowed the Byzantine Empire to survive when the Western Roman Empire fell. Unfortunately, even though the empire divided, Rome's situation worsened.  Persia had declared war on the Roman Empire and the ex-general Carausius had proclaimed himself Augustus and spurred Britain and Northern Gaul into open revolt. Though both Diocletian and Maximian had begun to retake Gaul and were winning the war in Persia, they needed more hands to deal with conflicts, so Maximian took Flavius Constantius as his second in command in 293, and Diocletian did the same with Galerius. Though Constantius and Galerius were below Diocletian and Maximian, all four had their own independent army and were pretty much independent from one another.  

Later Rule

The Tetrarchy with Diocletian, Maximian, Constantius, and Galerius added great benefit to the Empire. While Galerius was fighting battles in Persia, Diocletian was quelling revolts in the Balkans. Though this organization made the job of Diocletian easier, it also gave him time to persecute Christians. Diocletian and Galerius created a lot of persecutionary edicts towards Christians along with killing several of the Christian clergy and razing several Christian churches. Diocletian also issued an arrest for all Christian clergy. The persecutions, luckily, were for the most part unsuccessful. Most Christians escaped punishment, and people of other religions were mainly unsympathetic to the persecution. Also, Maximian and COnstantius did not apply most of the persecutionary edicts, leaving Western Christians unharmed. In 311, Galerius repealed the edicts, stating that they had failed to bring Christians back to traditional religion.

The End

In 304, Diocletian had just finished dedicating the opening of a circus when he collapsed. Diocletian's health was deteriorating, so on May 1, 305, Diocletion brought his generals, officers, and representatives to the hill, five kilometers out of Nicomedia, where he was appointed as Emperor after the death of Numerian. On that hill, he announced that he would be abdicating from his role as Augustus. Diocletian retired to Dalmatia where he created a palace for himself. After Maximian retired, Diocletian watched the political situation turn to chaos. The Tetrarchy collapsed and Maximian was forced to commit suicide after his third attempt to reclaim the throne. Diocletian died on December 3, 311, soon after Maximian. Diocletian made our list because he made the division in the Roman Empire that probably saved it for several hundred years and kept the Byzantine Empire alive after the fall of Rome in the West.

Saint Dionysius Exiguus (#94)

Background

Dionysius Exiguus, later known as Dennis the Humble, was born in in the Roman empire around the year A.D. 470. Little is known about his life, but most believe he was born in the section of the Roman Empire known as Scythia Minor. He was amember of the Scythian monks from the city of Tomis. Dionysius was a Catholic and was fluent in both Latin and Greek.

Works

The main work of  Dionysius  was a Scythian monk was to translate religious documents from Greek to Latin. His translated works include The Life of St. Pachomius and Instruction of St. Proclus of Constantinople. He also translated a history of the discovery of the head of St. John the Baptist. In total,  Dionysius  is said to have translated 401 ecclesiastical canons which were collected into the book Collectio Dionysiana. At the request of Pope John I in 525,  Dionysius  also created a table listing out all the future dates of Easter and a set of arguments justifying the calculations.  Dionysius  ignored the Easter Tables used by the Church of Rome that were prepared in 457 by Victorius of Aquitaine. He stated that they did not obey Alexandrian principles. His tables were not, however, used to calculate Easter, using, instead, the tables created by Cyril of Alexandria. By far, though,  Dionysius 's most famous work is as the inventor of the Anno Domini era. Using different references and documents,  Dionysius  calculated the year in which Jesus was born, stating that the year that he made this calculation was 525 years "since the incarnation of our Lord Jesus Christ." This year system was then applied to both the Julian and the Gregorian calender as a way of referencing the year. Before the birth of Jesus, the years are noted as B.C., or the years Before Christ. The years after the birth of Jesus are noted with A.D., or Anno Domini, or "In the Year of Our Lord. The Anno Domini era became dominant in Western Europe after it was used in 731 by the Venerable Bede to date events in his book, Ecclesiastical History of the English People. The Anno Domini year system is now the most used system of noting the year.

The End

Not much is known about the death of Dionysius Exiguus except that it was around the year A.D. 544. Dionysius is on our list because without him, we would really have a way of telling what year he did die in. Even though some people now use the notation C.E. and B.C.E. (Current Era and Before Current Era), they still are based on Dionysius's calculation of the birth of Jesus, and even though Dionysius's calculation are off by about three years, his system was still accepted and is used to this day. Without him, we wouldn't have any cool doomsday names like "Y2K" or "Twenty-Twelve."
