Nubians invaded Lower Egypt and took the throne of Egypt under Piye although they already controlled Thebes and Upper Egypt in the early years of Piye's reign. Piye's conquest of Lower Egypt established the Twenty-fifth Dynasty which ruled until 656 BC. They were ultimately driven back into Nubia, where they established a kingdom at Napata (656–590), and, later, at Meroë (590 BC – AD 500). Late Period The Late Period runs from around 664 to 332 BC, and includes periods of rule by native Egyptians and Persians. Twenty-Sixth Dynasty The Twenty-sixth Dynasty ruled from around 664 to 525 BC. The son and successor of Nekau I, Psamtik I, managed to reunify Egypt and is generally regarded as the founder of the Twenty-sixth Dynasty. Twenty-Seventh Dynasty Egypt was conquered by the Persian Empire in 525 BC and constituted a satrapy as part of this empire until 404 BC. The Achaemenid Shahanshahs were acknowledged as Pharaohs in this era, forming the 27th Dynasty: Several native rebellions took place during the 27th dynasty: Twenty-Eighth Dynasty The Twenty-eighth Dynasty lasted only 6 years, from 404 to 398 BC, with one pharaoh: Twenty-Ninth Dynasty The Twenty-ninth Dynasty ruled from 398 to 380 BC: Thirtieth Dynasty The Thirtieth Dynasty ruled from 379/8 until Egypt once more came under Persian rule 340 BC: Thirty-First Dynasty Egypt again came under the control of the Achaemenid Persians. After the practice of Manetho, the Persian rulers from 340 to 332 BC are occasionally designated as the Thirty-first Dynasty: Native rebellions again took place during the 31st dynasty: Hellenistic period Argead Dynasty The Macedonian Greeks under Alexander the Great ushered in the Hellenistic period with his conquest of Persia and Egypt. The Argeads ruled from 332 to 309 BC: Ptolemaic Dynasty The second Hellenistic dynasty, the Ptolemies, ruled Egypt from 305 BC until Egypt became a province of Rome in 30 BC (whenever two dates overlap, that means there was a co-regency). The most famous member of this dynasty was Cleopatra VII, in modern times known simply as Cleopatra, who was successively the consort of Julius Caesar and, after Caesar's death, of Mark Antony, having children with both of them. Cleopatra strove to create a dynastic and political union between Egypt and Rome, but the assassination of Caesar and the defeat of Mark Antony doomed her plans. Caesarion (Ptolemy XV Philopator Philometor Caesar) was the last king of the Ptolemaic Dynasty
