Cassander was a prominent figure in ancient Macedonian history, known for his role as a general and later as a king. He was a close associate of Alexander the Great and played a significant part in the power struggles that followed Alexander's death in 323 BCE. Cassander is best remembered for founding the city of Cassandreia and for his efforts to consolidate power in Macedonia. After the death of Alexander, Cassander became one of the key players in the Wars of the Diadochi, the conflicts among Alexander's former generals. He eventually seized control of Macedonia and ruled as king from 305 to 297 BCE. His reign was marked by political intrigue and conflict with other successors, including Antigonus and Ptolemy.
