Why did the Praetorian Guard support Claudius’s claim to the throne?

Following the murder of Caligula on January 24, 41 CE, the Praetorian Guard discovered Claudius in the palace and proclaimed him emperor the following day.12

The Guard's support for Claudius was secured primarily through financial incentives and the promise of a strong alliance. From the beginning of his reign, Claudius actively emphasized his friendship with the army and paid cash to the soldiers to ensure their loyalty and confirm his proclamation as emperor. While the Senate remained largely ambiguous or hesitant regarding his sudden rise to power, the imperial household troops—who had gained significant political influence—acted as the decisive force in establishing his authority.123
