1. Caesar
From 64 to 44 BC, the first three political periods in which Caesar, Pompeii and crassus lived ended the parliamentary system with the Senate as the power center. Crassus died in the battle to conquer the Parthian Empire, and later Caesar destroyed Pompeii. Later generations used his name Caesar to represent the title of king of Rome. On March 15th, 44 BC, Caesar was assassinated by domestic opponents Brutus and Gaius Cassius Longinus.
2. Octavian
43-27 BC, Caesar's nephew and grandson, was also his adopted son. Octavian became the heir, that is, Augustus the Great in history (the Senate granted him the title of Augustus in the 27th century BC, which means sacred and supreme in Latin). His rule with Anthony and Rabida is called the post-three-headed politics. Later, Octavian destroyed Antony and Rabida, and Octavian became the first official emperor of Rome, and Rome entered the imperial period.
3. Caligula
From 12 to 41 AD, gaius caesar Augustus Germanicus was the third emperor of the Roman Empire. "Caligula" is his nickname since childhood, which means "small military boots". It originated from the children's military boots that soldiers put on for him when he was a baby with his father, Nikustun, in the front line of Germanic. He was regarded as a typical tyrant in the early Roman Empire.
4. Claudius
Tiberius Claudius Drusus Nero Germanicus, whose full name is Tiberius Claudius Drusus nero germanicus, is often translated as Claudius, Claudius, or Tiberius Claudius Drusus Nero Germanicus, who used to be numbered after European monarchs, (August 1, 1-October 13, 54).
5. Antony
The Roman Empire flourished from 138 to 161 A.D., and its territory was unprecedented. The northern border reached Britain, West Germany, Austria, Hungary and Romania in contemporary Europe, and once reached the Euphrates River in West Asia in the east, including Egypt and Sudan in Africa in the south, Libya, Tunisia, Algeria and the Atlantic Ocean in the west. During the reign of Emperor Anthony, the situation was still relatively stable, which could still maintain the status quo of the empire.
