Egyptian chronology, which involves regnal years, began around this time.
The conventional chronology was accepted during the twentieth century, but it does not include any of the major revision proposals that also have been made in that time.
The Amratian culture is named after the site of el-Amreh, about 120 kilometres (75 mi) south of Badari.
El-Amreh was the first site where this culture was found unmingled with the later Gerzeh culture. Newly excavated objects indicate that trade between Upper and Lower Egypt existed at this time.
There also are several possible spellings of the names.
Typically, Egyptologists divide the history of pharaonic civilization using a schedule laid out first by Manetho's Aegyptiaca, which was written during the Ptolemaic Kingdom during the third century 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 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.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.The Badari culture, named for the Badari site near Deir Tasa, followed the Tasian; however, similarities mean many avoid differentiating between them at all.
