The Trojans charged a hefty fee for the use of their beach. Every night, the shepherds of Troy would look on the beach for the fires of any new arrivals. The new arrivals would be met the next morning by a troop of Trojan warriors. The ship owners could either pay the Trojan tax or be attacked.
Because of these questionable business practices, Trojan society was very rich and had goods from all over the world. They also angered other societies which finally led to the destruction of Troy during the Trojan War.
