Following the assassination of the Roman emperor Caligula on January 24, 41 CE, the Roman Senate initially considered restoring the republic. However, the Praetorian Guardâthe imperial household troopsâintervened and effectively forced the Senate to recognize Claudius as the new emperor.12
On January 25, 41 CE, the Praetorian Guard proclaimed Claudius emperor, a decision he solidified by emphasizing his friendship with the army and providing cash payments to secure their support. This event highlights the significant political influence the Praetorian Guard held in determining imperial succession during this period.23
