Claudius never had much luck with women during his life. His physical defects made engagements difficult. His first engagement was ended for political reasons and his second bride-to-be died on her way to the altar. He divorced his first wife on charges of adultery and trying to murder her sister in law, and his second marriage was to Sejanus's daughter, but Claudius divorced her quickly when Sejanus was accused of treason. His current wife was a member of Caligula's court called Valeria Messalina. The marriage worked out well, with Messalina happy to become part of the Imperial family, and Claudius was happy because she advocated for him not to be executed by the mad Caligula. She had two children, Claudia Octavia born in 39 AD, who will eventually marry Nero, and Brittanicus born in 41 AD, who was named after the recent victories in Britain. She worried about losing her newfound power because Claudius was getting older, 55, and had a history of medical problems, while the heir apparent, Brittanicus was still very young. With the help of Narcissus, she carried out a secret purge of anyone she saw as a threat, and because there were so many real assassination plots against Claudius, that whenever she brought a list of names, Claudius approved it without a second thought.
