As descendants of Ismail bin Sheikh Isaaq, its members form a part of the Habar Magaadle confederation which constitutes one of the largest sub-clans of the garhajis.

[6][7] The Ishaq Arreh and musa abdallah subclans of the Habr Yunis inhabit the Maroodi Jeex region of Somaliland.

Preserving bonds of interethnic clan relations with the Somali inhabited region...the Habr Yuunis from the vicinity of Hirna in Carcar joined the exodus to the west at the time of Amir Nur and occupied an area suitable for livestock-breeding east of Lake Zay.The sultanate was founded by the Rer Ainanshe sub branch of the Habr Yunis.

[17][18] The Sultan Deria Sugulleh would establish his capital at Wadhan (Waram) near the Sheikh pass and tax and administer the affairs of the Habr Yunis from the town.

Large caravans bound for Berbera would pass through Habr Yunis territory through Burao and then Wadhan and proved a lucrative source of income for Sultan Deria.

At nine o'clock we arrived at Baiadowal, on the Thug Dehr, a charming site, where the trees form a small forest, in which the most delightful coolness is enjoyed.

Kaysaha adduun Ina Ammaan koos dhan buu helaye Ragba keeno geli buu is-yidhi waad u korraysaaye Isba kii arsaa’ilay ma filin kamana yaabayne Ragow kibirka waa lagu kufaa kaa ha la ogaado With worldly pride Ina Ammaan gained a whole land Let all men put the horse's bit in their mouths He said to himself ‘You are on top’ But he didn't expect the one who killed him and was taken by surprise Oh men.

Describing the political situation in the region and frequent raids between the two rival Rer Sugulleh factions and their allied Habr Yunis subclans It appeared the great Habr Gerhajis tribe was divided into two rival factions, the one owning allegiance to Sultan Owd, the other to his cousin, Sultan Noor.

[26]The Haber-Gerhajis tribe had formerly been under one Sultan and were very powerful, making frequent raids into Ogadayn, but on his death, two cousins, Awad and Nur, divided the country between them.

The Baha Deria still did not concede defeat and would eventually choose Awad's nephew, Madar Hersi, as their successor following Nur's death.

[36] Madar was soon propagated as the legitimate Sultan by British authorities and managed the western sections of the clan throughout the period of the Dervish wars.

The most northerly is that of oneSoldan Nur of the Habr Yunis tribe; the next two, neither being plastered.and the first with the top left unfinished, are those of Hawiya notables whosenames my Somalis did not know.

"[39]After the Bombing campaign of the Taleh fort and the Dervish retreat into Ethiopia, Tribal Chief Haji Mohammad Bullaleh (Haji the Hyena), a cousin of Sultan Nur, commanded a 3000 strong army that consisted of Habr Yunis, Habr Je'lo and Dhulbahante warriors and pursued the fleeing Dervishes.

In 1841 Sharmarke with fifty Matchlock men, two cannons and an army of mounted spearmen managed to invade Zeila and depose its Arab Governor, Mohammed Al Barr.

[45][46] Sharmarke's governorship had an instant effect on the city, as he maneuvered to monopolize as much of the regional trade as possible, with his sights set as far as Harar and the Ogaden.

The Reer Yunis Nuh were expelled and moved to Bulhar[48] Sharmarke's influence was not limited to the coast as he had many allies in the interior of the Somali country and even further in Abyssinia.

[49] In 1855, in an act seen as defiant of foreign powers, Sharmarke refused to sell to M. Richet, the French agent at Jeddah, a house in Zeila, citing "how easily an Agency becomes a fort", and preferring "a considerable loss to the presence of dangerous friends".

In the ensuing riot and shootout between the British and Hersi Osman, Captain Allan Gibb, a Dervish war veteran and district commissioner, was shot and killed.

[51] The RAF planes arrived at Burao within two days and proceeded to Bomb the town with incendiaries, effectively burning the entire settlement to the ground.

Having called out Camel corps company to quell the disturbance, he went forward himself with his interperter, whereupon fire opened on him by some Rer segulleh riflemen and he was instantly killed..Miscreants then disappeared under the cover of darkness.

We propose to inflict fine of 2,500 camels on implicated sections, who are practically isolated and demand surrender of man who killed Gibbs.

[57]James Lawrence author of Imperial Rearguard: Wars of Empire writes [Gibb]..was murdered by rioters during a protest against taxation at Burao.

The inhabitants of the native township were turned out of their houses, and the entire area was razed by a combination of bombing, machine-gun fire and burning.

[58]After the RAF aircraft bombed Burao to the ground, the Hersi Osman eventually acquiesced, agreeing to pay a fine for Gibbs death, but they refused to identify and apprehend the accused individuals.

The SNM was organized in London, England, on 6 April 1981, by Hassan Adan Wadadid a former Somali diplomat and several other Isaaq intellectuals, he stated that the group's purpose was to overthrow the Siad Barre regime.

Habar Yoonis Commanders carried out many successful operations that led to the decisive victory of the group and to the downfall of the Siad Barre regime.

[62] Under the leadership of Abdirahman Ahmed Ali Tuur the SNM carried out a successful invasion of Northern Somalia overthrowing the Communist regime and establishing the democratic state of Somaliland.
