Nero

At first Nero until the age of fourteen, followed the honest principles which Seneca taught him, but soon his cruelty prevailed.
Since he was too young to rule, his mother Agrippina took his place but the wish to rule alone led him to commit one of the most terrible crimes that a man can commit: he killed his mother. The people were shocked, but Nero's cruelty did not stop. In 64 while he was at Anzio, Rome was burned down. It was interpreted as a Divine punishment, but in the end many people accused Nero of the fire, because he had often declared that he wanted to change Rome. The Christians paid for it, because Nero wanted to draw suspictions away from himself.
The reconstruction of the town was begun but Nero first wanted to build a magnificent house for himself which should be more luxurious than any other emperor's.
For the reconstruction he began to levy heavy taxes and tributes, and for this reason some noble men hatched a plot against him, but they were discovered and condemned to death. Among them was also Seneca. Nero continued with his life of waste and cruelty, he even condemned to the death all the rich nobles to confiscate their goods and gain money.
At the end his behaviour raised such indignation that the governor of Gaul, Vindice urged all the army leaders to join against the emperor. Vindice lost the battle but it was clear that the hostilities against the emperor were open.
Nero frightened, called back to Rome the troops from the Orient and surrounded himself with loyal men, but among them there were those who disapproved of him. Once he realized this he flew, but the soldiers reached him in his villa and while shouting that they were coming to arrest him, he committed suicide.
