What states were formed after the collapse of the Macedonian state?

The lands conquered by Alexander were distributed among the outstanding generals from his closest supporters – the Diadochs. The following people have built the strongest power. Seleucus took control of the far eastern lands of the new empire. Ptolemy established a lasting power in the province of Egypt. His descendants retained independent power longer than other Hellenistic monarchies. Antigonus took control of the original Macedonian lands and ruled over the Greek cities. Lysimachus ruled over the lands of the Thracians, loyal to the Macedonian throne.
