Here is what we know of Antiochus II Theos Born in 287 BCE to Antiochus I Soter and Stratonice I 268/7 BCE-Became heir apparent after Antiochus I had his older son, Seleucus, put to death for treason. Became King in 261 BCE after the death of his father Antiochus I, he begins making plans to avenge his fathers losses from the First Syrian War. Allied himself with the Macedonian King Antigonus II Gonatas against Ptolemy II Philadelphus between 261/0 BCE 260-253 BCE -The Second Syrian War: Antigonus wins several victories against Ptolemy in the Aegean, most notably the decisive naval victory at Cos between 261 and 255. 257 BCE Ptolemy II launches an invasion of Syria but almost nothing is known about this campaign; at best it was a status quo for Ptolemy II's forces. 257-253 BCE Antiochus II makes large gains in Asia minor against the forces of Ptolemy II. He liberates Miletus and deposes of the tyrant Timarchus, in gratitude the people of Miletus bestow Antiochus II the title of Theos (God). 257-253 BCE Antiochus II possibly invades Thrace or has some sort of presence in Europe. 253/2 BCE Ptolemy II negotiates for peace with Antiochus II and cedes large amounts of territory in Asia Minor to him. Antiochus II marries Ptolemy II's daughter Berenice. Antiochus receives a large payment as a dowry. 253-247 BCE Antiochus II divorces his first wife Laodice in favor of Berenice. He has a child with Berenice named Antiochus. 246 BCE Antiochus leaves his wife Berenice in Antioch with their son, confusingly named Antiochus, and heads to Asia Minor to visit his first wife and his two sons by her. Antiochus II is either posioned by Laodice or dies of natural causes at the age of 40 in July of 246. His remains are interred in the Belevi mausoleum in Ephesus. Mid to late 246/5 BCE Berenice and her son are murdered by partisans of Laodice, immediately starting a war with her brother Ptolemy III Euergetes. Seleucus II Callinicus, age 19, succeeds his father as King. Disputed- Parthia and Bactria declare independence in either 246 or more likely in 245 after the death of Antiochus II and amid the Third Syrian War. Unknown- Antiochus II receives numerous envoys from the pious buddhist King Ashoka of the Maurya empire concerning spiritual and medicinal tenants. So, after getting one coin of the man I had to get a spare. I absolutely love the facial expression and features of this coin and had to have it once I saw it.
