The Wars of the Diadochi, or Wars of Alexander's Successors, were a series of conflicts fought between the generals of Alexander the Great, known as the Diadochi, over who would rule his empire following his death. The fighting occurred between 322 and 281 BC.

Alexander III of Macedon, most commonly known as Alexander the Great, was a king of the ancient Greek kingdom of Macedon. He succeeded his father Philip II to the throne in 336 BC at the age of 20 and spent most of his ruling years conducting a lengthy military campaign throughout Western Asia, Central Asia, parts of South Asia, and Egypt. By the age of 30, he had created one of the largest empires in history, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered to be one of history's greatest and most successful military commanders.
