Gambela Region in the context of "Mezhenger Zone"

The Majang language is spoken by the Majangir people of Ethiopia. Although it is a member of the Surmic language cluster, it is the most isolated one in the group (Fleming 1983). A language survey has shown that dialect variation from north to south is minor and does not seriously impede communication. The 2007 Ethiopian Census lists 6,433 speakers for Majang (Messengo), but also reports that the ethnic group consists of 32,822 individuals (Messengo and Mejengir). According to the census, almost no speakers can be found in Mezhenger Zone of Gambela Region; a total of eleven speakers are listed for the zone, but almost 10,000 ethnic Mejenger or Messengo people.

Oromia (Oromo: Oromiyaa, Amharic: ኦሮሚያ) is a regional state in Ethiopia and the homeland of the Oromo people. Under Article 49 of Ethiopian Constitution, the capital of Oromia is Addis Ababa, also called Finfinne. The provision of the article maintains special interest of Oromia by utilizing social services and natural resources of Addis Ababa.

It is bordered by the Somali Region to the east; the Amhara Region, the Afar Region and the Benishangul-Gumuz Region to the north; Dire Dawa to the northeast; the South Sudanese state of Upper Nile, Gambela Region, South West Ethiopia Region, Southern Nations, Nationalities, and Peoples' Region and Sidama Region to the west; the Eastern Province of Kenya to the south; as well as Addis Ababa as an enclave surrounded by a Special Zone in its centre and the Harari Region as an enclave surrounded by East Hararghe in its east.

The Nilotic people are people indigenous to South Sudan and the Nile Valley who speak Nilotic languages. They inhabit South Sudan and the Gambela Region of Ethiopia, while also being a large minority in Kenya, Uganda, the northern area of Democratic Republic of the Congo, and Tanzania. The Nilotic people consist of the Dinka, the Nuer, the Shilluk, the Luo peoples, the Alur, the Anuak, the Ateker peoples, the Kalenjin people and the Karamojong people also known as the Karamojong or Karimojong, Ngasa people, Datooga, Samburu, and the Maa-speaking peoples. Each of the ethnic groups mentioned have distinct languages, ethnic origins, and migration history, so the grouping under the name Nilotic or Nilotes is anthropologically contentious.

The Nilotes constitute the majority of the population in South Sudan while constituting a substantial minority in the countries of Uganda, Tanzania and Kenya. They make up a notable part of the population of North eastern Democratic Republic of Congo as well. Nilotic people are believed to number 50 million in the 21st century.

The Nuer language (Thok Naath, "people's language") is a Nilotic language of the Western Nilotic group. It is spoken by the Nuer people of South Sudan and in western Ethiopia (region of Gambela). The language is very similar to Dinka and Atuot.

The language is written with a Latin-based alphabet. There are several dialects of Nuer, although all share one written standard. For example, final /k/, is pronounced in the Jikany dialect but is dropped in other dialects despite being indicated in the Nuer orthography used by all.

The Nuer people are a Nilotic ethnic group concentrated in the Greater Upper Nile region of South Sudan. They also live in the Ethiopian region of Gambella. The Nuer speak the Nuer language, which belongs to the Nilotic language family. They are the second-largest ethnic group in South Sudan and the largest ethnic group in Gambella, Ethiopia. The Nuer people are pastoralists who herd cattle for a living. Their cattle serve as companions and define their lifestyle. The Nuer call themselves "Naath".

The Anyuak, also known as Anyuaa and Anywaa, are a Luo Nilotic ethnic group inhabiting parts of East Africa. The Anuak belong to the larger Luo family group. Their language is referred to as Dha-Anywaa. They primarily reside in the Gambela Region of western Ethiopia, and South Sudan. Group members number between 200,000 and 300,000 people worldwide. Many of the Anyuak people now follow Christianity. It is one of the first of the Nilotic groups to become almost entirely Christian, following the Shilluk people.
