Wei Pasian

At the end of 68, unrest broke out in the Roman capital, Nero committed suicide, and Garpa became the new emperor. Verpasian, who was engaged in the Jewish Campaign, temporarily suspended military operations. In early 69, Garba was killed by Otto, who became emperor. However, the Germanic Corps refused to accept and made Vistrius emperor. Vitrius marched on Rome and fought Otto for supremacy. At this time, Verpasian was watching and watching the situation change and did not express his support for either party. In April 1969, the first Battle of Bedriacum ended, the Vitrius faction defeated, Otto committed suicide, and Vitrius was recognized as Roman Emperor by the Senate.

After the battle, the defeated Pannonian Army refused to accept it. They joined forces with the Moesian Army, who had not participated in the first Bedriacum battle, and Muchianus, the commander of the Syria Army in the east, to jointly support Vepsian, who became emperor of the Jewish Army. Soon after, Tiberius Alexander, the governor of the Egyptian province, also expressed his support for Verpasian. On July 1, 1969, Vepasian proclaimed himself emperor and entered the Egyptian city of Alexandria.

In September, the Eastern Army entered Italy, made contact with the army that had captured Vistrius (also known as the Second Battle of Bedriacum), and captured Cremona. After that, the Eastern Legion won consecutive battles and entered Rome in December and killed Vitrius. At this point, Vespasian became the only Roman emperor.
