Herod Antipas had a brother, Philip, who was married to Herodias. Herod Antipas fell in love with Herodias, divorced his wife and married her. Philip died. It is unclear whether Antipas had anything to do with his death but the treachery of Herod the Great is well documented and certainly his offspring were no better. John the Baptist was imprisoned for speaking out against Antipas’ divorce and marriage to his brother’s wife. The house of Herod reeked of evil intrigue and skullduggery.
Salome was the daughter of Herodias.
