Twenty-seventh Dynasty of Egypt in the context of "Hieroglyphs"

Ancient Egyptian hieroglyphs (/ˈhaɪroʊˌɡlɪfs/ HY-roh-glifs) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic, and alphabetic elements, with more than 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic. Hieroglyphs are thought to be one of four writing systems developed without outside influence, the others being Cuneiforms, Chinese characters, and Mayan script.

The use of hieroglyphic writing arose from proto-literate symbol systems in the Early Bronze Age c. the 33rd century BC (Naqada III), with the first decipherable sentence written in the Egyptian language dating to the 28th century BC (Second Dynasty). Ancient Egyptian hieroglyphs developed into a mature writing system used for monumental inscription in the classical language of the Middle Kingdom period; during this period, the system used about 900 distinct signs. The use of this writing system continued through the New Kingdom and Late Period, and on into the Persian and Ptolemaic periods. Late survivals of hieroglyphic use are found well into the Roman period, extending into the 4th century AD.

The history of Persian Egypt refers to the two periods when ancient Egypt was controlled by the Achaemenid Empire:

• Twenty-seventh Dynasty of Egypt (525–404 BC), established by the first Achaemenid conquest of Egypt.
• Thirty-first Dynasty of Egypt (343–332 BC), established by the second Achaemenid conquest of Egypt.

These two periods of satrapies were punctuated by a brief interval of Egyptian independence from 404 BC to 343 BC.

Xerxes I (/ˈzɜːrksiːz/ ZURK-seez; c. 518 – August 465 BC), commonly known as Xerxes the Great, was a Persian ruler who served as the fourth King of Kings of the Achaemenid Empire, reigning from 486 BC until his assassination in 465 BC. He was the son of Darius the Great and Atossa, a daughter of Cyrus the Great.

In Western history, Xerxes is best known for his invasion of Greece in 480 BC, which ended in Persian defeat. Xerxes was designated successor by Darius over his elder brother Artobazan and inherited a large, multi-ethnic empire upon his father's death. He consolidated his power by crushing revolts in Egypt and Babylon, and renewed his father's campaign to subjugate Greece and punish Athens and its allies for their interference in the Ionian Revolt. In 480 BC, Xerxes personally led a large army and crossed the Hellespont into Europe. He achieved victories at Thermopylae and Artemisium before capturing and razing Athens. His forces gained control of mainland Greece north of the Isthmus of Corinth until their defeat at the Battle of Salamis. Fearing that the Greeks might trap him in Europe, Xerxes retreated with the greater part of his army back to Asia, leaving behind Mardonius to continue his campaign. Mardonius was defeated at Plataea the following year, effectively ending the Persian invasion.

The first Achaemenid conquest of Egypt took place in 525 BCE, leading to the foundation of the Twenty-seventh Dynasty of Egypt, also known as the "First Egyptian Satrapy" (Old Persian: Mudrāya). Egypt thus became a satrapy of the Achaemenid Empire until 404 while still maintaining Egyptian royalty customs and positions. The conquest was led by Cambyses II, who defeated the Egyptians at the Battle of Pelusium (525 BCE), and crowned himself pharaoh. Achaemenid rule was disestablished upon the rebellion and crowning of Amyrtaeus as Pharaoh. A second period of Achaemenid rule in Egypt occurred under the Thirty-first Dynasty of Egypt (343–332 BCE).
