Teos (Ancient Greek: Τέως) or Tachos (Ancient Greek: Τάχως), Egyptian Djedhor, 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.

Teos (Greek: Τέως; demonym: Τήϊος) or Teo was a maritime city of Ionia, on a peninsula between Chytrium and Myonnesus, colonized by Orchomenian Minyans, Ionians, and Boeotians. The city is situated on a low hilly narrow strip of land connecting two larger areas of land (isthmus). Teos ranked among twelve cities comprising the Ionian League. It was a member of the Lydian group of the Ionian League, one of the four groups defined by Herodotus, based on the particular dialects of the cities. It was the birthplace of Anacreon the poet, Hecateus the historian, Protagoras the sophist, Scythinus the poet, Andron the geographer, and Apellicon, the preserver of the works of Aristotle.

Teos was a flourishing seaport with two fine harbours until Cyrus the Great invaded Lydia and Ionia (ca. 540 BC). The Teans found it prudent to retire overseas, to the newly founded colonies of Abdera in Thrace and Phanagoria on the Asian side of the Cimmerian Bosporus. The port was revived by Antigonus Cyclops; and Epicurus reportedly studied there under Nausiphanes, a disciple of Democritus. During the times of the Roman emperors, the town was noted for its wine, a theatre and Temple of Dionysus. These are positioned near the acropolis, which is situated on a low hill and had fortifications by the sixth century.

Egypt ⁱ/ˈiːdʒɪpt/ (Arabic: مصر, Miṣr, Egyptian Arabic: [mɑsˤɾ] ; Coptic: Ⲭⲏⲙⲓ, Kīmi ; Sahidic Coptic: ⲕⲏⲙⲉ, Kēme), officially the Arab Republic of Egypt, Arabic:  جمهوريّة مصر العربيّة (help·info), is a country mainly in North Africa, with the Sinai Peninsula forming a land bridge in Southwest Asia. Egypt is thus a transcontinental country, and a major power in Africa, the Mediterranean Basin, the Middle East and the Muslim world. Covering an area of about 1,010,000 square kilometers (390,000 sq mi), Egypt is bordered by the Mediterranean Sea to the north, the Gaza Strip and Israel to the northeast, the Red Sea to the east, Sudan to the south and Libya to the west.

Egypt is one of the most populous countries in Africa and the Middle East. The great majority of its over 81 million people live near the banks of the Nile River, in an area of about 40,000 square kilometers (15,000 sq mi), where the only arable land is found. The large areas of the Sahara Desert are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.
