The Praetorian Guard was a force of bodyguards used by Roman Emperors from around 275 BC until the 4th century when they were dissolved by Emperor Constantine I. Galba (3 BC-69 AD) was a Roman Emperor for seven months from 68 to 69. Galba's primary concern during his brief reign was restoring state finances, and to this end he undertook a number of unpopular measures, the most dangerous his refusal to pay the praetorians the reward promised in his name. Galba scorned the notion that soldiers should be "bribed" for their loyalty. After the emperor Galba failed to provide a donative for the Praetorians, they transferred their allegiance to Otho and assassinated the emperor. Otho acquiesced in the Praetorians' demands and granted them the right to appoint their own prefects, ensuring their loyalty.
