They formulated a plan to invade and conquer the Peloponnesus, a significant portion of southern Greece comprised of a peninsula extending into the Aegean Sea. In the meantime, Hyllus and his warlike brothers had ambitions of their own. For all of Eurystheus’ bluster, however, he was defeated in the ensuing conflict. Eurystheus refused her offer and war broke out. The sister of Hyllus, Macaria, sought to avoid the conflict by offering herself up to Eurystheus as a sacrifice. Most feared Eurystheus would inflict enormous damage upon Athens by waging all-out our war on the city. He demanded that the rulers of Athens turn over the children of Heracles or face a devastating attack on the city. This did not sit well with Eurystheus, however. They eventually sought refuge in Athens and were granted a safe haven there. This meant that Hyllus and his siblings were thrown into exile. The city-states were instead given over to the rule of Eurystheus, the king of Mycenae. However, through the vindictive meddling of the goddess Hera, Heracles was robbed of his inheritance. Before his death, Heracles was promised the rulership of three powerful city-states, Argos, Lacedaemon and Pylos. The exploits of Hyllus play out after the death of his father.
