In 144, Sohaemus received the Armenian throne from the Roman emperor
Antoninus Pius after the death of
Vologases I. In honor of his first ascent to the throne of Armenia, a sestertius with images of Sohaemus and Antoninus Pius was issued in Rome with the inscription "A king given to the Armenians". Sohaemus was a contemporary to the rule of the
Roman emperors Antoninus Pius,
Marcus Aurelius,
Lucius Verus and
Commodus of the
Nerva–Antonine dynasty. In his first reign, he ruled from 144 to 161. Not much is known about his first reign. The novelist Iamblichus living in Armenia at the time of his rule describes his reign as ‘in succession to his ancestors’. After Armenia was seized by the Parthians, Sohaemus went into political exile, living in
Rome where he became a senator. These events provoked a new
Roman-Parthian war and peace was made on Roman terms, with Sohaemus reinstalled as King of Armenia by Lucius Verus in either 163 or 164. The ceremony for Sohaemus becoming King of Armenia for the second time may have taken place in
Antioch or
Ephesus. This war cost Rome dearly, because the victorious army brought back with it from the east a plague that spread very quickly throughout the empire. Emperor
Marcus Aurelius tried to declare Armenia a province of Rome, but the uprising of Armenians led by Prince Tiridates forced the Romans to abandon their plans. In 164, Latin coinage was struck in Armenia with the inscription
L. Verus. Aug. Armeniacus and on the reverse
Rex Armen(ii)s datus. == Second period of Rule ==
