Claudius Proclaimed Emperor of Rome
On January 25, 41, according to Roman sources, the senator and historian Claudius was proclaimed emperor by the Praetorian Guard after the assassination of his nephew Caligula. Found reportedly hiding behind a curtain in the palace, Claudius was an unlikely choice, long dismissed as bookish and physically frail. His elevation marked a decisive moment in the Julio-Claudian dynasty, ushering in a reign that expanded the empire's borders, especially in Britain, and strengthened imperial administration in ways that would echo across later Roman rule.
