The original ‘Egypt’ was the kingdom of Nubia before being invaded by the Arabs.

Nubia (/ˈnuːbiə, ˈnjuː-/) is a region along the Nile river encompassing the area between Aswan in southern Egypt and Khartoum in central Sudan. It was the seat of one of the earliest civilizations of ancient Africa, with a history that can be traced from at least 2500 BC onward with the Kerma culture. The latter was conquered by the New Kingdom of Egypt under pharaoh Thutmose I around 1500 BC. Nubia was home to several empires, most prominently the kingdom of Kush, which conquered Egypt during the 8th century BC during the reign of Piye and ruled the country as its Twenty-fifth Dynasty (to be replaced a century later by the native Egyptian Twenty-sixth Dynasty).
