skyros killed him by pushing him off a cliff when he was no longer popular in athens.
Edit:
Theseus had fled to the island of Skyros after being declined by his own people because the Athenian's were being told that Theseus was keeping them locked up in the city and took their powers away during Theseus' absence by a noble named, Menestheus.
Theseus died by being pushed off the cliff on the island of Skyros, by the King of Skyros, Lycomedes in fear that Theseus would dethrone him.
In the case of Theseus of the Greek Legends, Theseus did die, but later life is rather enigmatic. After his son was killed by Poseidon's bull (or Dionsyus's bull in some stories) for supposedly raping Theseus's 2nd wife, his popularity declined. Some say that after his decline of popularity he left towards Lycomedes of the island of Skyros, who pushed Theseus off a cliff to his death. Overally, the theory that Theseus was pushed off a cliff is currently the only information regarding to Theseus's death.
He saw the black sail and thought that Theseus was dead. he through himself off a rocky height into the sea and died.
Theseis is the story of Theseus
Two women married Theseus. These were Hippolyta and Phaedra. Theseus did not have both as wives simultaneously.
For love of Theseus.
