The Kingdom of Kush, also known as the Kushite Empire, or simply Kush, was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt.

The ancient Egyptian Hill-country or "Foreign land" hieroglyph (𓈉) is a member of the sky, earth, and water hieroglyphs. A form of the hieroglyph in color, has a green line-(banding) at the base of the hieroglyph. The hieroglyph refers to the hills, and mountains, on both sides of the Nile River, and thus the green references the verdant black farming land adjacent to the river proper. It is coded N25 in Gardiner's sign list, and U+13209 in Unicode. It is a determinative hieroglyph, simply conveying a meaning, and has no phonetic value.
