Demetrius I Poliorcetes vs Mentuhotep II

Demetrius commanded the Macedonian fleet to a decisive victory over Ptolemy I's navy off Salamis, Cyprus. He destroyed or captured much of the Ptolemaic fleet, allowing him to conquer Cyprus and establish a base for his father Antigonus I Monophthalmus.

Demetrius Poliorcetes besieged the city of Rhodes with massive siege engines, including the Helepolis, a 130-foot siege tower. After a year-long siege, he failed to capture the city and was forced to withdraw, but his innovative siege techniques earned him the epithet 'Poliorcetes' (Besieger of Cities).

After a period of chaos in Macedon, Demetrius seized the throne and was proclaimed king. He ruled Macedon for seven years, attempting to restore Antigonid power and launch campaigns to reclaim his father's empire in Asia.

After being defeated by Lysimachus and Pyrrhus, Demetrius fled to Asia Minor but was captured by Seleucus I. He was held in honorable captivity in Apamea, where he died three years later from illness and excessive drinking, ending his turbulent career.

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.
