The Karamojong or Karimojong are an ethnic group of agro-pastoral herders living mainly in the north-east of Uganda. Their language is also known as Karamojong or Karimojong, and is part of the Nilo-Saharan language group.
The Karamojong live in the southern part of the region in the north-east of Uganda, occupying an area equivalent to one tenth of the country. According to anthropologists, the Karamojong are part of a group that migrated from present-day Ethiopia around 1600 A.D. and split into two branches, with one branch moving to present day Kenya to form the Kalenjin group and Maasai cluster. The other branch, called Ateker, migrated westwards. Ateker further split into several groups, including Turkana in present-day Kenya, Iteso, Dodoth, Jie, Karamojong, and Kumam in present-day Uganda, also Jiye and Toposa in southern Sudan all of them together now known as the "Teso Cluster" or "Karamojong Cluster".
It is said that the Karamojong were originally known as the Jie. The name Karamojong derived from phrase "ekar ngimojong", meaning "the old men can walk no farther". According to tradition, the peoples now known as the Karamojong Cluster or Teso Cluster are said to have migrated from Abyssinia between the 1600 and 1700 AD as a single group. When they reached the area around the modern Kenyan-Ethiopian border, they are said to have fragmented into several groups including those that became Turkana, Toposa, and the Dodoth. The group that became known as the Toposa continued to present day southern Sudan; the Dodoth, settled in Apule in the northern part of present-day Karamoja. The Turkana settled in Kenya where they are now and today's Jie of Uganda are thought to have split from them, moving up the escarpment into today's Kotido District. The main body continued southwards, reportedly consisting of seven groups or clans who settled in today's southern Karamoja, eventually merging to become the three clans now existing: the Matheniko in the east around Moroto mountain, the Pian in the south and the Bokora in the west. However, a significant sized group went west and formed the Iteso, the Kumam, and the Langi. It was this group who were said to have used the phrase "the old men can walk no farther".
