He became the youngest-ever Roman Emperor
Nero was born on December 15, 37 AD, as "Lucius Domitius Ahenobarbus" at Antium, a town located about 51 kilometers (32 miles) south of Rome. Agrippina the Younger, his mother, was a notorious Roman emperor known as Caligula who ruled the empire from 41 to 37 A.D. Agrippina the Younger was also the sister of the similarly notorious Gaius Julius Caesar.
In addition, Nero was the sole child of Augustus, the first emperor of the Roman Empire, and Julia. Nero's biological father, Domitius, passed away in January of the year 40 AD when he was just 2 years old. After Caligula was killed in the year 41 AD, Claudius, another member of the Julio-Claudian dynasty, was crowned emperor and raised Nero as his own child.
Agrippina the Younger, the mother of Nero, supposedly poisoned Claudius in the year 54 AD so that her son would succeed as the only heir apparent to the throne. Nero rose to power as the youngest Roman emperor in history on October 13 of the year 54 AD. He was only 16 years old and less than 2 months away from becoming 17. After three other unsuccessful attempts in the Year of the Four Emperors following Nero's death, he would rule for 13 years and 8 months before taking his own life. Vespasian would then come to power and founded the Flavian Dynasty, which is best known for building the Flavian Amphitheater or The Colosseum.
