Valerian II

Valerian II was appointed Caesar (junior emperor) by his father Gallienus, ruling over the eastern provinces. This appointment was part of the Valerian dynasty's efforts to secure imperial succession during the Crisis of the Third Century.

Valerian II accompanied his father Gallienus on a campaign against the Sasanian Empire in Mesopotamia. The campaign was inconclusive, with both sides suffering losses, but it demonstrated Roman efforts to defend the eastern frontier.

Valerian II died under unclear circumstances, possibly murdered by the usurper Ingenuus or during a military campaign. His death at a young age ended the Valerian dynasty's plans for stable succession and contributed to the empire's instability.
