The Twenty-Eighth Dynasty is often combined with other groupings of rulers of ancient Egypt under the title, Late Period. These other groupings include the Twenty-Sixth, Twenty-Seventh, Twenty-Ninth, Thirtieth, and Thirty-First dynasties.
The Twenty-Eighth Dynasty had one ruler, Amyrtaeus, who was a descendant of the Saite kings of the Twenty-Sixth Dynasty. He led a successful revolt against the Persians on the death of Darius II, ending the provincial First Satrapy of Achaemenid Egypt (Twenty-eighth Dynasty).
No monuments from the reign of pharaoh Amyrtaeus have been found, and little is known of his 5 year reign.
