Editing Perdiccas (section)

==== Conquest of Cappadocia ====
Despite success in the east, Perdiccas' authority as regent was then challenged in the west. Here, Perdiccas had appointed [[Leonnatus]], another {{Transliteration|grc|somatophylax}}, as satrap of [[Phrygia|Hellespontine Phrygia]] on the western coast of [[Asia Minor]].{{sfn|Heckel|2016|p=172}} At the Partition of Babylon, Perdiccas' supporter Eumenes was given the satrapies of [[Cappadocia]] and [[Paphlagonia]], but both were unconquered.{{sfnm|Anson|2015|1p=78|Heckel|2006|2p=121}} Perdiccas thus used his authority as regent of the joint kings to order Leonnatus and [[Antigonus I Monophthalmus|Antigonus]] (satrap of [[Phrygia]], [[Pamphylia]] and [[Lycia]]) to aid Eumenes in securing his satrapy.{{sfn|Heckel|2016|p=172}}{{sfn|Plut. ''Eum.''|loc=3.2}} Perdiccas probably gave Eumenes 5000 [[Talent (measurement)|talents]] of gold for the reconquest of Cappadocia, allowing Eumenes to hire mercenaries.{{sfn|Anson|2015|p=80}}

Antigonus refused Perdiccas' order.{{sfn|Plut. ''Eum.''|loc=3.5}} Leonnatus accepted, mustering an army and marching to Cappadocia, arriving in the spring of 322&nbsp;BC.{{sfn|Heckel|2016|p=172}} Leonnatus, however, received a letter from Macedon from [[Cleopatra of Macedon|Cleopatra]], Alexander the Great's full sister, and Antipater, both asking him to come west – Cleopatra (probably influenced by her mother [[Olympias]]) offered herself as Leonnatus' bride (which would give Leonnatus claim to the Macedonian throne), while Antipater, who was besieged at [[Lamia (city)|Lamia]] by the Greeks led by [[Leosthenes]] as part of the [[Lamian War]], asked Leonnatus for urgent assistance.{{sfn|Heckel|2016|p=172}} Leonnatus told Eumenes of his plan to head west, attempting to convince him to join him; Eumenes refused and departed to Perdiccas' court, informing him of Leonnatus' intentions.{{sfn|Heckel|2016|p=172}} For this information, Perdiccas elevated Eumenes to the ruling council of the Empire.{{sfnm|Heckel|2016|1p=172|Waterfield|2011|2p=38}}{{sfn|Anson|2015|p=84}} This incident may have been what made Perdiccas "regard Cleopatra as a means of gaining supreme power".{{sfn|Heckel|2016|p=173}}

Upon learning of Leonnatus' departure, in the early summer of 322&nbsp;BC Perdiccas marched the imperial army towards [[Asia Minor]] to reassert his dominance as regent, install Eumenes in Cappadocia, and confront Antigonus. It also allowed him to "complete the conquest of Alexander's empire" as Alexander had ignored Cappadocia.{{sfn|Anson|2014|p=47}}{{sfn|Heckel|2016|pp=172-173. Alexander had installed a satrap there, but the man disappears from history and Ariarathes is known to have been in revolt, independent, throughout Alexander's "reign" over Cappadocia}} In a single campaigning season, Perdiccas defeated [[Ariarathes I]] and his large army (30,000 infantry, 15,000 cavalry) in two decisive [[pitched battles]], capturing more than 5,000 soldiers and killing 4,000 others, allowing his supporter Eumenes to claim his satrapy.{{sfnm|Anson|2014|1p=47|Diod.|2loc=18.16.2}} This greatly contributed to Perdiccas' prestige; Perdiccas took Ariarathes captive, [[torture]]d and killed him, and apparently [[impalement|impaled]] most of his family.{{sfn|Heckel|2016|p=173, who notes the cruel nature of this treatment. Perdiccas likely wanted no more trouble in Cappadocia, but evidently Ariarathes I's family line survived; see: [[Ariarathes II]]}} Perdiccas ordered Leonnatus to appear before him to stand trial for disobedience, but Leonnatus died during the [[Lamian War]] before the order reached him. At some time during the first year of his reign, Perdiccas crowned Alexander IV, Roxana and Alexander's child, as king alongside Philip III.{{sfn|Bosworth|2005|p=62. When it occurred is not known exactly; Bosworth places it at the end of Perdiccas' Cappadocian conquest}}
