Answer:
The Hellenistic world eventually settled into four stable power blocks: the Ptolemaic Kingdom of Egypt, the Seleucid Empire in the east, the Kingdom of Pergamon in Asia Minor, and Macedon.
The Macedonian generals carved the empire up after Alexander's death (323 BC); these were the successors (the Diadochi), founders of states and dynasties—notably Antipater, Perdiccas, Ptolemy I, Seleucus I, Antigonus I, and Lysimachus.
