What war came after the Trojan war?

After the Trojan War, the most significant conflict in Greek mythology is often considered to be the War of the Seven Against Thebes. This war involved a coalition of seven champions who besieged Thebes in an attempt to install Polynices as king, following the events of the Theban cycle, which includes the stories of Oedipus and his descendants. The aftermath of the Trojan War also set the stage for various Greek city-state conflicts, but the War of the Seven Against Thebes is the primary mythological war that follows directly.
