Britannicus (41-55 CE) was the second child and only son born to the Roman emperor Claudius (r. 41-54 CE) and Valeria Messalina (c. 20-48 CE). Seen as a threat by Claudius' fourth wife, Agrippina the Younger (15-59 CE), and her son, the future Nero (r. 54-68 CE), Britannicus was poisoned the night before his 14th birthday.
