Seleucus III Ceraunus

Seleucus III Ceraunus, later also known as Soter, was the eldest son of Seleucus II Callinicus and Laodice II, and for a few years—between 226/5 and 223 BCE—king of the Seleucid Empire. His epithets mean "Thunderbolt" and "Savior," while his birth name was Alexander. In 225 BCE, following the death of his father Seleucus II—who succumbed to injuries from a fall from his horse—Seleucus III succeeded him as king of the Seleucid Empire. In 223 BCE, he was assassinated in Asia Minor by courtiers during a campaign against Attalus I of Pergamon. His brother Antiochus subsequently ascended the throne.
