The Year of the Four Emperors was a year in the history of the Roman Empire, AD 69, in which four emperors ruled in a remarkable turnover. The four emperors were Galba, Otho, Vitellius, and Vespasian.

The suicide of emperor Nero, in 68, was followed by a brief period of civil war, the first Roman civil war since Mark Antony's death in 30 BC. Between June of 68 and December of 69, Rome witnessed the successive rise and fall of Galba, Otho and Vitellius until the final accession of Vespasian, the first ruler of the Flavian Dynasty.

This was an example of the political disturbances which occurred in the history of the Roman Empire. The military and political anarchy created by this civil war had serious repercussions, such as the outbreak of the Batavian rebellion. The Jewish Revolt was already ongoing.
