Which king of Troy caused the sack of the city by refusing to pay Heracles?

The king of Troy who caused the sack of the city by refusing to pay Heracles is indeed Laomedon. This incident is rooted in Greek mythology, where Laomedon struck a deal with Heracles to build the walls of Troy in exchange for a set reward, typically described as horses or gold. However, once the work was completed, Laomedon failed to fulfill his promise and refused to pay Heracles.

In retaliation for this betrayal, Heracles assembled a fleet to attack Troy. His subsequent siege and the eventual conquering of the city were significantly influenced by this unfulfilled promise. This myth illustrates themes of honor and loyalty that were vital in ancient Greek culture, showcasing the consequences of dishonoring agreements. Laomedon’s refusal to honor his commitment to Heracles led directly to the downfall of Troy, marking him as a pivotal figure in that tragic narrative.

The other figures mentioned, such as Priam, Hector, and Menelaus, are notable in the context of the Trojan War but did not play a direct role in the events surrounding Heracles or the sack of Troy that stemmed from Laomedon’s actions.
