Between June 68 and December 69, Rome witnessed the successive rise and fall of Galba, Otho and Vitellius until the final accession of Vespasian, first ruler of the Flavian dynasty. The military and political anarchy created by this civil war had serious implications, such as the outbreak of the Batavian rebellion. These events showed that a military power alone could create an emperor.[31] Augustus had established a standing army, where individual soldiers served under the same military governors over an extended period of time.
