The C-Group culture is an archaeological culture found in Lower Nubia, which dates from ca. 2400 BCE to ca. 1550 BCE. It was named by George A. Reisner. With no central site and no written evidence about what these people called themselves, Reisner assigned the culture a letter. The C-Group arose after Reisner's A-Group and B-Group cultures, and around the time the Old Kingdom was ending in Ancient Egypt. Overview While today many scholars see A and B as actually being a continuation of the same group, C-Group is considered as the product of Saharan pastoralist distinct. The C-Group is marked by its distinctive pottery, and for its tombs. Early C-Group tombs consisted of a simple "stone circle" with the body buried in a depression in the centre. The tombs later became more elaborate with the bodies being placed in a stone lined chamber, and then the addition of an extra chamber on the east: for offerings. The origins of the C-Group are still debated. Some scholars see it largely being evolved from the A/B-Group. Others think it more likely that the C-Group was brought by invaders or migrants that mingled with the local culture, with the C-Group perhaps originating in the then rapidly drying Sahara. The C-Group were farmers and semi-nomadic herders keeping large numbers of cattle in an area that is today too arid for such herding. Originally they were believed to be a peaceful people due to the lack of weapons in tombs; however, daggers, short swords and battle-axes were found in C-Group graves. Their settling around the forts built by the ancient Egyptians was seen as further evidence. Most of what is known about the C-Group peoples comes from Lower Nubia and the Dongola Reach. The northern border of the C-Group was around el-Kubanieh near Aswan. The southern border is still uncertain, but C-Group sites have been found as far south as Eritrea. During the Egyptian Sixth Dynasty, Lower Nubia is described of consisting of a number of small states, three of which are named: Setju, Wawat, and Irjet. At this same time in Upper Nubia the Kingdom of Kerma was emerging. The exact relation between the C-Group and Kerma are uncertain, but early Kerma shows definite similarities to the C-Group culture and the Pan-Grave culture. Under the Middle Kingdom much of the C-Group lands in Lower Nubia were conquered by Egypt; after the Egyptians left,
