Crossing the Rubicon. January 10, 49 BC.

During the Roman Republic, the river Rubicon marked the boundary between the Roman province of Cisalpine Gaul to the north-west and Italy proper (controlled directly by Rome and its allies) to the south. Exercising imperium when forbidden by the law was a capital offence. Furthermore, obeying the commands of a general who did not legally possess imperium was a capital offence. If a general entered Italy whilst exercising command of an army, both the general and his soldiers became outlaws and were automatically condemned to death. Generals were thus obliged to disband their armies before entering Italy. In 49 BC, perhaps on January 10, Julius Caesar led a single legion, south over the Rubicon from Cisalpine Gaul to Italy to make his way to Rome. In doing so, he deliberately broke the law o...

The Julian Calendar. January 1, 45 BC.

  In the mid-1st century BCE Julius Caesar invited astronomer Sosigenes of Alexandria to advise him about the reform of the calendar, and Sosigenes decided that the only practical step was to abandon the lunar calendar altogether. Months must be arranged on a seasonal basis, and a tropical (solar) year used, as in the Egyptian calendar, but with its length taken as 365 1/4 days. To remove the immense discrepancy between calendar date and equinox, it was decided that the year known in modern times as 46 BCE should have two intercalations. This insertion amounted to an addition of 67 days, making a year of no less than 445 days and causing the beginning of March 45 BCE in the Roman republican calendar to fall on what is still called January 1 of the Julian calendar. Previous errors havi...

Justin´s madness forces his abdication. December 7, 574.

  As insanity invaded the mind of Justin, he became aware that he had to name a colleague for succession of his throne. Passing over his own relatives, he raised, on the advice of his wife Sophia, the general Tiberius to be Caesar in December 7 574, adopting him as his son, and withdrew into retirement. According to John of Ephesus, as Justin II slipped into the madness of his final days he was pulled through the palace on a wheeled throne, biting attendants as he passed. He reportedly ordered organ music to be played constantly throughout the palace in an attempt to soothe his frenzied mind. The tardy knowledge of his own impotence determined him to lay down the weight of the diadem; he showed some symptoms of a discerning and even magnanimous spirit when he addressed his assembly, Y...

Emperor Diocletian and the Tetrarchy. November 20, 284 AD.

After his rise through the ranks of military until he became the Roman Cavalry Commander to Emperor Carus, when Carus and his son Numerian died on campaign in Persia, Diocletian became emperor on November 20, 284. Of course, Carus surviving son, Carinus also claimed the title, but was defeated in the battle of Margus.  Diocletian´s rule put an end to the Crisis of the Third Century. Diocletian named his fellow officer Maximian co-emperor,  Augustus, in 286. Afterwards, in 293, he named caesars Galerius and Constantius, or heirs of the augustus title. This new regime was called the Tetrarchy, or “government of four”, and it meant the geographical division of the empire into four parts. Diocletian lead military campaigns against Sarmatians, Carpi, Alemanii, and the usurpers in Egypt, securin...

End of the Siege and Battle of Alesia. 5 October, 52 BC.

The Siege and Battle of Alesia meant the end of the Gallic Wars, and took place from September to October 52 BC. It befell around the Gallic fortified settlement of Alesia, “capital” of the Mandubii tribe. It confronted the Roman army of Julius Caesar against an alliance of Gallic tribes, united under the leadership of Vercingetorix of the Averni. In history, it is considered one of Caesar´s most important military victories, as well as a classic example of siege warfare. This battle marked the end of the Gallic independence of France and Belgium. The day after the battle, Caesar ordered the Gauls to surrender their weapons and deliver their chieftains. The chieftains were brought before him and Vercingetorix was surrendered. For Caesar, Alesia was an enormous personal success, both milita...
