Its modern name is one of many borrowings in Egyptian Arabic from Coptic, the last living phase of Ancient Egyptian. In Graeco-Roman times, it was called Apollonopolis Parva or Apollinopolis Mikra (Greek: Ἀπόλλωνος ἡ μικρά;[5]Ἀπόλλων μικρός),[6] or Apollonos minoris.[7]
During the Roman Empire it was renamed Diocletianopolis; and it corresponds, probably, to the Maximianopolis of the later Empire.
In the late Old Kingdom and First Intermediate Period, important people of Qus were buried at Naqada at the other side of the Nile. Here were found several stelae belonging to local governors of Qus, including those of Hetepi (priest).
Gesa was an important city in the early part of Egyptian history. Because at that time it served as the point of departure for expeditions to the Red Sea. The city gradually lost its importance, only to regain it in the 13th century with the opening of an alternate commercial route to the Red Sea. Since then, Qus replaced Qift as the primary commercial center for trading with Africa, India, and Arabia. It thus became the second most important Islamic city in medieval Egypt, after Cairo.
Today, Qus is the site of a major American/German commercial project to convert the waste products of sugar cane refining (bagasse) into paper products.[citation needed]
The census of 2017 recorded a population in Qus of 464,288, which was estimated to have increased to 512,827 in 2021.[1]
^The numbering of the Ptolemaic rulers can differ in several sources. The numbering used by Porter and Moss seems to be off by 1 compared to Wikipedia. The internal links are based on the second name used. For instance Ptolemy Alexander I is numbered Ptolemy X on Wikipedia, while he is numbered Ptolemy XI in Porter and Moss.
