Since Theseus is a mythological figure, and cannot be directly tied to an actual person (his reign would have been during the bronze age, before the recording of history as we know it), no dates are given. However, we know that his son, Acamas, was sent on his behalf to fight in the Trojan War, which was esitmated to have been fought between 1194 and 1184 BC. So it's safe to assume that Theseus reigned from the mid 12th to late 12th century BC.
