Answer:
This statement is partially correct. Upon returning to Athens after defeating the Minotaur in Crete, Theseus did meet with King Aegeus, who was his father and showed him the white sails of his ship, indicating that he had been successful and had survived the dangerous mission. However, King Aegeus did not recognize the meaning of the white sails and assumed that Theseus had failed and died. As a result, he threw himself into the sea in despair, giving his name to the Aegean Sea.
After the death of King Aegeus, Theseus became the new king of Athens and led the city into a new era of success. He is famous for his many accomplishments, including the unification of Attica, the establishment of a commonwealth, and the creation of the Panathenaic Games. However, it was not his victory over the Minotaur that directly led to his ascent to the throne, but rather the tragic events that followed his return to Athens.
