Commercial Rivalry
Along with the generally acknowledged causes of the conflict, Sparta and Troy's trade rivalry is a far more plausible explanation. You might find it amusing to learn that the conflict was nothing more than a tactical move utilized by many gods and monarchs to further their own goals. The Trojan War was fought in the Bronze Age city of Troy. It had high, steep walls and was well-built, as Homer said. It had been an impenetrable city center surrounded by concrete for nine years.
The reader gets the impression that Troy was unbreakable from Homer's narrative. It was located on a Hellenistic battleground, a city that had withstood several vicious assaults. Agamemnon allegedly had a long-standing desire for the wealth of Troy. The Spartans were tempted to do that as well as expand the boundaries of their government. They viewed this as the ideal chance to assault Troy to capture whatever is both theirs and Troy itself. As a result, Agamemnon gathers Achaean soldiers and makes preparations for their excursions. The official start of the war is therefore underway at Sparta.
