Amyrtaios was the only ruler of the Twenty-eighth Dynasty. He is thought to have been a
Libyan. He ruled Egypt from Sais for six years. He began his reign after the death of Darius II
when there was a renewed revolt in Egypt. They achieved independence for a short time
again. On the Elephantine Papyri, there is documentation of a loan contract that is written in
the year 5 of this king. This is indication that he was recognized in Upper and Lower Egypt.
He must have driven the Persians out of the whole country.
