Editing 321 BC (section)

==== Macedonian Empire ====
* [[Antipater]] appoints [[Antigonus I Monophthalmus|Antigonus]] commander in chief of his army in [[Asia Minor]] and sends him with [[Craterus]] to fight against [[Eumenes]], the [[satrap]] of [[Cappadocia]] and a supporter of [[Perdiccas]].
* Leaving [[Eumenes]] to hold [[Asia Minor]] against [[Craterus]] and Antigonus, Perdiccas marches against [[Ptolemy I Soter|Ptolemy]], but when he fails to cross the [[Nile]] he is murdered by mutinous officers. Prominent among the mutineers is [[Seleucus I Nicator|Seleucus]]. A truce is arranged, leaving Ptolemy in power in [[Ancient Egypt|Egypt]] and Seleucus in power in [[Babylon]].
* The key remaining generals ([[diadochi]]) of the late [[Alexander the Great]] agree to the [[Partition of Triparadisus]] (a town in northern [[Syria]]). This is a power-sharing agreement providing for a new regent to replace Perdiccas and it repartitions the satrapies of the empire that has been created by Alexander the Great. It follows but modifies the [[Partition of Babylon]] made two years earlier following the death of Alexander the Great. Under the agreement, Antipater becomes the regent of the Macedonian Empire on behalf of the two kings: the intellectually retarded [[Philip III Arrhidaeus]] and the infant [[Alexander IV of Macedon]] while Ptolemy is confirmed in possession of Egypt and [[Cyrene, Libya|Cyrene]].
* Ptolemy further strengthens his position amongst the diadochi by marrying [[Eurydice of Egypt|Eurydice]], the third daughter of Antipater.
* Antigonus and Craterus defeat Eumenes in battle but Eumenes escapes. Antigonus and Craterus then besiege him unsuccessfully in the mountain fortress of Nora on the border between [[Cappadocia]] and [[Lycaonia]]. Craterus is killed during the fighting against Eumenes when his charging horse (Diodorus) falls over him.
