The Old Kingdom and its royal power reached their zenith under the Fourth Dynasty. Sneferu, the dynasty's founder, is believed to have commissioned at least three pyramids; while his son and successor Khufu (Greek Cheops) erected the Great Pyramid of Giza, Sneferu had more stone and brick moved than any other pharaoh. Khufu, his son Khafra (Greek Chephren), and his grandson Menkaure (Greek Mycerinus) all achieved lasting fame in the construction of the Giza pyramid complex.

The Tasian culture was the next to appear; it existed in Upper Egypt starting about 4500 BC. This group is named for the burials found at Deir Tasa, a site on the east bank of the Nile between Asyut and Akhmim. The Tasian culture is notable for producing the earliest blacktop-ware, a type of red and brown pottery painted black on its top and interior.[6]

The Badari culture, named for the Badari site near Deir Tasa, followed the Tasian; however, similarities mean many avoid differentiating between them at all. The Badari culture continued to produce the kind of pottery called blacktop-ware (although its quality was much improved over previous specimens), and was assigned the sequence dating numbers between 21 and 29. The significant difference, however, between the Tasian and Badari, which prevents scholars from completely merging the two, is that Badari sites are Chalcolithic while the Tasian sites remained Neolithic and are thus considered technically part of the Stone Age.
