[5][6] Garre are also classified into three major entities of the same lineage but greatly recognized for their unique linguistics characteristics which are widely believed to have developed after their wide dispersal around the Horn of Africa, Garre Libin are speakers of Oromo whom it is believed they had a long time interaction and intermixing as nomads in southern Ethiopia and Northern Kenya.

The Garre Somalis colonised the Barava-Bajun region, the NFD of Kenya, and Bale province in Ethiopia before the Boorana and Warday Oromo.

This show's indeed the Somali saying "tol waa tolane'' (clan is something joined together) and the structure is not based on blood relationship, that is why you will find Garre is closely affiliated with Tunni and Jiido of the Lower Jubba Valley.

Curle made the following observation in 1933: ...around the mosque oat Au Bakadleh in the Hargeisa District of the British Somaliland, there are many graves of this type, exact replicas of those on the Dawa some found some 500 miles distance in the Garre country.

[37] They occur in four large autonomous groups: on the lower reaches of the Shebelle in Audegle District around Dolo on the upper jubba, between the Webi Gestro and the Webi Mana in contact and to some extent intermixed with the Arsi Oromo, and to the south-west between the Ajuran and Degodia Somali and the Boran Galla of the Northern Frontier Province of Kenya.

As a whole, the Garre are nomadic pastoralists with large numbers of camels, sheep, goats and where the habitat is suitable, they settle and domesticate their cattle.

The Proto-Reewin, the ancestors of the modern Reewin families (Digil and Mirifle), occupy a unique position both linguistically and culturally in the historical development, migration and settlement in the area south of the Shabelle River.

In many cases, however, this type of organization, dependent for its structure on a dominant clan, is superseded by a system of territorial groups whose political relations are not expressed genealogically.

Many years ago a number of them made an invasion to the south-west, across the Dawa River, into which the country was occupied by the Wardey, who were a "suffara" (Somali) tribe.

[41] The Garre were the descendants of the Somalis who drove back the boran to the west, but unlike their brethren who have become the Gabra migo, they remained in the country they had occupied in the sufficient numbers to maintain their independence.

[43] An unpublished Garre tradition collected at Mandera c.1930 by Pease, a British colonial administrator, touches on the Garre-Katwa link.

The majority crossing the Juba but a small party from the Killia, Bana and Birkaya [Sections].. turned aside at the Juba to make for the coast between Kismayu and Lamu, where they settled with the Bajun[43] Garre exerted considerable influence on the formation of the present-day characteristics of the Bajuni whom the Bajuni-Katwa claims them as their ancestors and perhaps were at one time Garre clients.

They also participated in long-distance trade networks that extended to Arabia, India, and other parts of Africa i.e. Ethiopia, contributing to the sultanate's economic success.

The Garre people, along with other Somali clans such as the Issa and the Dir, are mentioned as having supported the Adal Sultanate in its conflict with the Ethiopian empire.

The author of "Futuh Al-Habasha," Shihab al-Din Ahmad ibn Abd al-Qadir al-Fatati, describes Sultan Mataan Cismaan Khalid was a powerful warrior from the Garreh, Girreh tribe.

The women are in charge of domestic duties, such as preparing the meals, milking the animals, caring for the children, and actually building the home.

[46] Clan identity is traced exclusively in the male line through their father's paternal genealogy (abtirsiinyo: literally “counting ancestors,” in Somali).

[48] On the other hand, the Dir, largely in Somaliland, mix well with the Isaaq, the Garre and the Degodia, with closer sub-clans being the Biyamal, Gadsan, and Werdai among others.

[49] Despite the heavy emphasis on camel husbandry the production system of the Garre includes important cattle and crop components.

[50][51][52] The Garre were renowned as breeders of burden camels, they supplied the Somalis and Oromos caravaneers of the Jubba Basin the eighteenth century and probably much earlier.

Following the decline of the Ajuraan state in the mid-seventeenth century and after the scene of many conflicts during the age of Oromo expansion, was gradually becoming stabilized.

Along that frontier there evolved a number of bilingual trading settlements, coupled with the integrating force of Islam, these developments facilitated the creation of regional exchange networks.

The most important inland market towns in southern Somalia were Luuq[56] and Baardheere, on the Jubba River; Baydhabo (Baidoa) and Buur Hakaba in the central inter-river plain; and Awdheegle and Afgooye along the lower Shabeelle.

[57][52] Although the inland market centers were small—only the towns along the Shabeelle numbered more than two thousand permanent residents—they were frequented by nomads, farmers, and peddlers from the surrounding districts.

In essence, they were small "ports of trade" that offered security and a degree of political neutrality to buyers and sellers from a variety of different clans and locales.

Goods originating in the Jubba basin were brought to the towns of Luuq and Baardheere in caravans manned by traders from upcountry clans: Garre and Ajuraan.

From the Jubba River towns, Gasar Gudda, Eelay, and Garre traders carried the goods to Baydhabo and Buur Hakaba, to Awdheegle and Afgooye.

In Ethiopia, they live in Moyale, Hudet, Mubarak, Qadaduma, Suruba, Raaro, Lehey and Woreda of Dawa zone.

[65] The Confer (Kofar) country lies beyond Rahanweyn in the coastal area, the principal Gurreh towns or villages being Shan and Musser on the Owdegli i.e. the lower reaches of the Shebelle River where it runs parallel with and close to the sea coast between Mogadishu and Merca.

[67] The following genealogy has been derived from the work of Professor L.M.Lewis, also taken also from the World Bank's Conflict in Somalia: Drivers and Dynamics[68] from 2005 and the United Kingdom's Home Office publication, Somalia Assessment 2001,[69] and The Total Somali Clan Genealogy (second edition), African Studies Centre Leiden, Netherlands[16] The tribes of Garre have a well-defined patrilineal genealogical structure, The lineage of Garre Mohamed-Garre bin Yusuf (Gardere) bin Samaale, and subsequently Samaale, traced from Abu Talib ibn Abd al-Muttalib The Garre are divided into the Tuff and Quranyow sub-clans.
