In 335, Hannibalianus, Constantine the Great's nephew, married his cousin, Constantine's elder daughter, Constantina, and was made nobilissimus. Hannibalianus was named rex regum et Ponticarum gentium (King of the Pontic Land and Peoples) in early 337. It was Constantine's intention to put Hannibalianus on the Pontic throne, after the defeat of the Sassanid Persians. However, the Persian campaign did not take place, because Constantine died in May 337. Later in 337, Hannibalianus, Dalmatius and many other male relatives, were murdered at the behest of one or all of Constantine's sons (though they denied it). Hannibalianus was the Roman king who never actually ruled any territory.
