Who were emperor galba's enemies?

Answer 1

Galba was first of the emperors of the Year of the Four Emperors (68-69) in which four men fought over the imperial title.

The events started when the Praetorian (Imperial) Guard switched their loyalty from the emperor Nero to Galba, the governor on one of the Provinces in Hispania. Galba marched on Rome with a legion. Finding himself without support Nero committed suicide. Galba entered Rome and was proclaimed emperor and. However, he was unpopular. He executed many senators without trial and did not pay a reward which the Praetorian Guard expected. The legions in the province of Germania refused to swear loyalty to him and proclaimed Aulus Vitellius, the governor of their province, emperor, who got half of these legions to march on Rome. The childless Galba adopted a young senator and designated him as his successor, which angered many people. It also spoiled the plans Otho had to secure the succession. Otho bribed the Praetorian Guard, which proclaimed him emperor and murdered Galba. He then had to face the advance on Rome by legions of Germania. He was defeated in a battle in northern Italy and committed suicide to prevent the civil war from continuing. The senate recognised Vitellius as the new emperor. However, Vitellius was a profligate and cruel ruler. The legions in the east, Syria, Judea and Egypt proclaimed Vespasian, who had been given command of the Roman troops sent to suppress the Great Revolt in Judea, emperor. Vespasian prepared to march on Rome. The legions of the provinces on the river Danube, which were closer to Rome, also proclaimed Vespasian emperor and advanced on Rome ahead of Vespasian's troops, defeated Vitellius'' troops in northern Italy, reached Rome, seized the city and killed Vitellius.

Galba rules for seven month, Otho for three months and Vitellius for eight months.
