Teos was the second ruler of the Thirtieth Dynasty and was the son of his predecessor, Nectanebo I. After his father
had died, Teos took over the throne and planned an attack on the Persians. He had the help of mercenaries from Greece,
but his own generals disagreed with his leadership and the entire event was a fiasco. He was deserted by both the
Greeks and the Egyptians. He fled to Persia by way of Arabia and Artaxerxes II, the ruler of Persia, gave him refuge.
He lived in Persia until his death.
Teos was Pharaoh of Egypt between the years of 362 to 360 BC;
he had been co-regent with his father Nectanebo I from about
365. He was overthrown by Nectanebo II with the aid of
Agesilaus II of Sparta and was forced to flee to Persia by way
of Arabia. The Persian king Artaxerxes II gave him refuge, and
Teos lived in Persian exile until his death.
