The Anabasis of Alexander was composed by Arrian of Nicomedia in the second century AD, most probably during the reign of Hadrian. The Anabasis is a history of the campaigns of Alexander the Great, specifically his conquest of the Persian Empire between 336 and 323 BC. Both the unusual title "Anabasis" and the work's seven-book structure reflect Arrian's emulation of the Greek historian Xenophon, whose own Anabasis in seven books concerned the earlier campaign "up-country" of Cyrus the Younger in 401 BC.

Parmenion, son of Philotas, was a Macedonian general in the service of Philip II of Macedon and Alexander the Great. A nobleman, Parmenion rose to become Philip's chief military lieutenant and Alexander's strategos. He was assassinated after his son Philotas was convicted on a charge of treason. His siblings Asander and Agathon would also become prominent members of Alexander's Macedonia.
