Eumenes I
Encyclopedia : E : EU : EUM : Eumenes I
Eumenes I of Pergamon (died 241 BC1), son of Eumenes the brother of the founder of the Attalid dynasty, Philetaerus. Eumenes was the adopted son and heir of Philetaerus, succeeding him upon his death in 263 BC, as ruler of Pergamon until his own death in 241 BC.
Although nominally under Seleucid control, Pergamon under Philetaerus enjoyed considerable autonomy. However upon his succession, Eumenes, perhaps with the encouragement of Ptolemy II who was at war with the Seleucids, revolted, defeating the Seleucid king Antiochus I near the Lydian capital of Sardis in 262 BC. He was thus able to free Pergamon, and greatly increase the territories under his control, establishing garrison posts in the north at the foot of Mount Ida called Phileraerus after his adoptive father, and in the east, northeast of Thyatira near the sources of the river Lycus, called Attalea after his grandfather, as well as extending his control south of the river Caïcus to the Gulf of Cyme.
After the revolt from the Seleucids, there are no records of any further hostilities involving Pergamon during the Eumenes' rule, even though there continued to be conflict between the Seleucids and the Ptolemies, and even though the Gallatian Gauls were continually plundering throughout the region. If Eumenes was able to keep Pergamon free from the ravages of the Gauls, it was probably due to the fact that he paid them tribute.2
Although never assuming the title of "king" Eumenes did exercise all of the powers of one.3 He was succeeded by his second cousin, Attalus I Soter.4
