Roman Emperor Nero ruled from 54 to 68 AD and is often remembered for his controversial reign. He became emperor at the age of 16 and was the last ruler of the Julio-Claudian dynasty. His rule was marked by significant events, including the great fire of Rome in 64 AD, which led to widespread destruction and rumors that he had started the fire himself. Nero was known for his artistic ambitions and often participated in public performances, which was unusual for a Roman emperor. His reign ended in turmoil, leading to his downfall and eventual suicide, marking the beginning of a period of civil wars known as the Year of the Four Emperors.
