Eumenes II
Eumenes II visited Rome in 172 BC. During his visit, Eumenes II expressed his hostility towards King Perseus of Macedon. He informed the Roman Senate about Perseus' alleged plans to gain influence in Greece. On his return to Pergamon, Eumenes II was attacked near Cirrha and was thought at the time to have been killed. Eumenes' brother Attalus II Philadelphus became king and married Stratonice. When Eumenes II returned, his brother ceded power and Stratonice returned to Eumenes II.
