Claudius
On 24 January 41 CE, Caligula was assassinated by a broad-based conspiracy. There is no evidence that Claudius had a direct hand in the assassination, although it has been argued that he knew about the plot. In the chaos following the murder, Claudius witnessed the German guard cut down several uninvolved noblemen, including some of his friends. He fled to the palace to hide. According to tradition, a Praetorian named Gratus found him hiding behind a curtain and suddenly declared him emperor. A section of the guard may have planned to seek out Claudius, perhaps with his approval. They reassured him that they were not one of the groups looking for revenge. He was put under their protection.
