Mentuhotep II vs Valerian

Mentuhotep II, a Theban ruler, conquered the rival Heracleopolitan kingdom, reunifying Upper and Lower Egypt. This victory ended the First Intermediate Period and established the Middle Kingdom, with Mentuhotep II as its first pharaoh.

Mentuhotep II built a terraced mortuary temple at Deir el-Bahri, blending rock-cut and free-standing architecture. The temple, with its colonnades and pyramid, became a model for later New Kingdom structures and symbolized his reunification.

Valerian was proclaimed emperor by his troops after the death of Trebonianus Gallus. He appointed his son Gallienus as co-emperor, dividing the empire into eastern and western halves for administration. This arrangement aimed to address multiple external threats but ultimately failed to prevent Valerian's capture.

Valerian led a Roman army against the Sasanian Empire under Shapur I near Edessa. The Roman forces were defeated and Valerian was taken prisoner, becoming the first Roman emperor to be captured in battle. This event severely damaged Roman prestige and triggered a crisis of leadership.

Valerian died while a prisoner of the Sasanian king Shapur I. Accounts vary on the manner of his death, with some sources claiming he was used as a footstool by Shapur or flayed and his skin displayed. His death left the Roman Empire without a senior Augustus, worsening the Crisis of the Third Century.
