Partition of Triparadisus

The Partition of Triparadisus was a power-sharing agreement passed at Triparadisus in 321 BCE between the generals (diadochi) of Alexander the Great, in which they named a new regent and established the repartition of their satrapies. It followed and modified the Partition of Babylon made in 323 BCE upon the death of Alexander the Great. Following the death of Alexander the Great in 323 BCE, the rule of his empire was given to his half-brother Philip Arrhidaeus and Alexander's son Alexander IV. However, since Philip was mentally ill and Alexander IV born only after the death of his father, a regent was named in Perdiccas. In the meantime, the former generals of Alexander were named satraps of the various regions of his Empire.

Several satraps were eager to gain more power, and when Ptolemy, satrap of Egypt, rebelled with other generals, Perdiccas moved against the former, but was killed by a mutiny in his camp. Ptolemy declined the regency, and instead brought to the office Peithon and Arrhidaeus. This designation met the strong opposition of Eurydice, wife of king Philip III, leading, in the meeting called in 321 BCE at Triparadisus of all the diadochi, to their replacement with Antipater. The meeting also proceeded to divide again the satrapies between the various generals.
