During that same, the emperor Nero was declared a public enemy by the Senate and committed suicide, and the period of civil war known as the Year of the Four Emperors began. Galba succeeded Nero, but was murdered in early 69 by Otho, who took the throne. Agricola's mother was murdered on her estate in Liguria by Otho's marauding fleet. Hearing of Vespasian's bid for the empire, Agricola immediately gave him his support. Otho meanwhile committed suicide after being defeated by Vitellius.
