Ptolemy came to terms with Perdiccas' murderers, making Peithon and Arrhidaeus regents in Perdiccas's place, but soon these came to a new agreement with Antipater at the Treaty of Triparadisus. Antipater was made Regent of the Empire, and the two kings were moved to Macedon. Antigonus was made Strategos of Asia and remained in charge of Phrygia, Lycia, and Pamphylia, to which was added Lycaonia. Ptolemy retained Egypt, Lysimachus retained Thrace, while the three murderers of Perdiccas—Seleucus, Peithon, and Antigenes—were given the provinces of Babylonia, Media, and Susiana respectively. Arrhidaeus, the former regent, received Hellespontine Phrygia. Antigonus was charged with the task of rooting out Perdiccas's former supporter, Eumenes. In effect, Antipater retained for himself control of Europe, while Antigonus, as Strategos of the East, held a similar position in Asia.
