Historical Notes:
Seleukos II ruled over the expansive Seleukid Empire during a fraught period.  At the very outset of his reign in 246 BC, the Empire was immediately embroiled in a war against Ptolemaic Egypt, which it ultimately lost.  Following the conclusion of the war, Seleukos had to deal with the rebellion of his brother, Antiochos Hierax.  In the midst of these troubles, the Seleukids lost control of Baktria, and the Kingdom of Pergamon occupied their territories in Asia Minor.  As he was planning to move against the Pergamese, Seleukos fell off his horse and died from his injuries.
