From the Archaic to Classical period, the archaeological evidence of well-stocked graves establishes Tenedos's continuing affluence. Tall, broad-mouthed containers show grapes and olives were likely processed during this time. They were also used to bury dead infants. By the fourth century BC, grapes and wine had become relevant to the economy of the island. Tenedians likely exported surplus wine. Writings from this era talk of a shortage of agricultural land, indicating a booming settlement. A dispute with the neighboring island of Sigeum was arbitrated by Periander of Corinth, who handed over political control of a swath of the mainland to Tenedos. In the first century BC this territory was eventually incorporated into Alexandria Troas.
