Antigonus I Monophthalmus
As regent and commander-in-chief, Perdiccas considered it important to consolidate Alexander's empire. A key step in achieving this was to conquer Cappadocia which still remained under Persian rule. However, Antigonus I Monophthalmus, the Macedonian satrap of Pamphylia and Lycia, was unwilling to support Perdiccas when in 322 BC Perdiccas successfully invaded Cappadocia. When Perdiccas ordered Antigonus to appear before his court, Antigonus fled to Antipater's court in Macedonia.
