Treaty 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 arranged the repartition of the satrapies of Alexander's empire among themselves. It followed and modified the Partition of Babylon made in 323 BCE upon the Alexander's death.

Following the death of Alexander, 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 Philip III, leading, in the meeting called in 321 BCE at Triparadisus of all the generals, to their replacement with Antipater. The meeting also proceeded to divide again the satrapies between the various generals.

Arrian described the result of the meeting in Events after Alexander, which were transmitted to us by the Byzantine patriarch Photius (820–897):
