Servius Sulpicius Galba, born as Lucius Livius Ocella Sulpicius Galba, was a Roman emperor who ruled from AD 68 to 69. He was the first emperor in the Year of the Four Emperors and assumed the position following Emperor Nero's suicide. Galba's physical weakness and general apathy led to him being selected over by favorites. Unable to gain popularity with the people or maintain the support of the Praetorian Guard, Galba was murdered by Otho, who became emperor in his place.

A military coup drove Nero into hiding. Facing execution at the hands of the Roman Senate, he reportedly committed suicide in 68. According to Cassius Dio, Nero's last words were "Jupiter, what an artist perishes in me!".

Titus, Vespasian's successor, quickly proved his merit, although his short reign was marked by disaster, including the eruption of Mount Vesuvius in Pompeii. He held the opening ceremonies in the still unfinished Colosseum but died in 81.

Han and allied forces defeated the army of the Northern Chanyu and accepted the surrender of two hundred thousand Xiongnu soldiers in the Altai Mountains.

Julianus was sentenced to death.
