Antigonus was one of Alexander the Great's successors. He was among those who ruled smaller empires that were created after Alexander's death out of the area that Alexander had conquered.
Antigonus was one of Alexander's generals. After Alexander died, Antigonus was involved in the struggles to control the area that Alexander had conquered. Antigonus wanted to rule the whole empire by himself but was unable to defeat his rivals in battle. Instead, Antigonus was able to keep control only of Macedonia and the surrounding area. Antigonus's holdings came to be known as the Antigonid Kingdom and were able to remain powerful in the area until the Romans came in the 2nd century BCE.
