According to the "Historia Augusta", Hadrian informed the Senate of his accession in a letter as a "fait accompli", explaining that "the unseemly haste of the troops in acclaiming him emperor was due to the belief that the state could not be without an emperor". The new emperor rewarded the legions' loyalty with the customary bonus, and the Senate endorsed the acclamation. Various public ceremonies were organised on Hadrian's behalf, celebrating his "divine election" by all the gods, whose community now included Trajan, deified at Hadrian's request.
