Hephaestion The Conqueror (Empire of Hephaistion, Alexander and Craterus)

Macedon Empire Post-Alexander
Upon Alexander the Great's death in 323 BC Hephaestion was crowned Emperor of Macedon. Emperor Hephaestion immediately began a campaign westward to conquer the Roman Republic and Carthaginian Empire. Rome fell in 319 AD and Carthage in 316 AD, and would be remembered as Hephaestion the Conqueror. Hephaestion died in 314 AD to be succeeded by his son, Aeropus.

Aeropus

During Aeropus' reign the Macedon Empire invaded and conquered the Iberian Penninsula, the south of OTL France, and Africa out to the Atlantic Ocean to the west of what was the Carthaginian Empire. Aeropus helped stabilize the empire. His policies perpetuated a unified Macedon identity throughout the empire.

Continuation

Over the next few centuries the Macedon Empire would expand, taking the Arabian Penninsula, and sometimes extending further north in Europe. They extended into Central Asia around 250 BC and then into India around 125 BC. Around 10 BC Indian rebels gradually regained control. During this time lands in Central Asia at times change hands with Scythia.
