Antigonus I Monophthalmus
In 321 BCE, at the division of the provinces, after the death of the regent Perdiccas, he gained the position of satrap of Cappadocia. He attached himself to the party of Antigonus I Monophthalmus, whom he accompanied in the war against Eumenes. After the Battle of Gabiene, the mutinous Argyraspids agreed to surrender their general into Antigonus's hands; it was Nicanor who was selected to receive the prisoner from them.
