Leo II vs Mausolus

Leo I proclaimed his grandson Leo II as co-emperor of the Eastern Roman Empire. This was done to secure the succession for the young boy, who was the son of Zeno and Ariadne. Leo II was only six years old at the time.

Upon the death of Leo I, Leo II became the sole Eastern Roman Emperor. Due to his young age, his father Zeno was appointed as regent and co-emperor shortly thereafter, effectively ruling in his stead.

Leo II died of a disease, likely natural causes, after a reign of less than a year. His death left Zeno as the sole emperor, ending the brief reign of the child emperor and preventing any long-term impact of his rule.

Mausolus was appointed satrap of Caria by Artaxerxes II, succeeding his father Hecatomnus. He ruled Caria as a semi-independent vassal, expanding its power and influence.

Mausolus moved the capital of Caria from Mylasa to Halicarnassus. He transformed the city with grand buildings, including a palace and fortifications, making it a major cultural and political center.

Mausolus expanded Carian territory through military campaigns, annexing parts of Lycia, Ionia, and the Greek islands. He increased Caria's power and wealth, making it a major regional state.

Mausolus began construction of his monumental tomb at Halicarnassus, known as the Mausoleum. It was designed by Greek architects and decorated by famous sculptors, becoming one of the Seven Wonders of the Ancient World.
