Eyl District ( Somali : Degmada Eyl ) is a district in the northeastern Nugal region of Somalia . Its capital is Eyl .
117-576: Eyl District was once a major hub for dervish movement in the early 1900s , with Sayid Mohamed Abdille Hassan operating in the area and using Eyl as a base to launch attacks on British and Italian colonies. Eyl served as one of the coastal bases for the Dervish movement. It was strategically important because it allowed the Dervishes to receive supplies and weapons from the coast, which were crucial for sustaining their long-running resistance. Today, Eyl

Human malaria causes symptoms that typically include fever , fatigue , vomiting , and headaches . In severe cases, it can cause jaundice , seizures , coma , or death . Symptoms usually begin 10 to 15 days after being bitten by an infected Anopheles mosquito . If not properly treated, people may have recurrences of
585-478: A Somali "proto-state", according to Markus Hoehne. It was a mobile state with fluid boundaries and fluctuating population given the guerilla style militant approach of Dervishes and their practice of retreating to sparsely inhabited hinterland whenever the colonial forces with superior firearms overwhelmed them. At the head of this state was the Sufi leader Hasan with the power of final decision. Hasan surrounded himself with
702-442: A Sufi tariqa (order) sometime in the 1930s, where he preached his ideology of anti-imperialism, stressing the evil of colonial rule and the bringing of radical change through war. His ideology was shaped by a millennial bent, which according to Marxist historian Eric Hobsbawm is the "hope of a complete and radical change in the world shorn of all its present deficiencies". The Dervish movement would subsequently inspire Sheikh Bashir ,
819-575: A blood meal from a previously Plasmodium infected person or animal. Parasites are then typically introduced by the bite of an infected Anopheles mosquito. Some of these inoculated parasites, called " sporozoites ", probably remain in the skin, but others travel in the bloodstream to the liver , where they invade hepatocytes . They grow and divide in the liver for 2–10 days, with each infected hepatocyte eventually harboring up to 40,000 parasites. The infected hepatocytes break down, releasing these invasive Plasmodium cells, called " merozoites ", into

Malaria is commonly associated with poverty and has a significant negative effect on economic development. In Africa, it is estimated to result in losses of US$ 12 billion a year due to increased healthcare costs, lost ability to work, and adverse effects on tourism. The term malaria originates from Medieval Italian : mala aria 'bad air',

By the close of the 19th century, the European colonial powers expanded their reach in the Horn of Africa , the region of Somalia came under the influence of the British, Ethiopians and the Italians. The withdrawal of the Egyptian troops from Harar enabled Ras Makonnen and Menelik II to expand
1287-472: A greater likelihood of complications and death. Malaria infection affects the immune responses following vaccination for various diseases. For example, malaria suppresses immune responses to polysaccharide vaccines. A potential solution is to give curative treatment before vaccination in areas where malaria is present. Due to the non-specific nature of malaria symptoms, diagnosis is typically suspected based on symptoms and travel history, then confirmed with

Due to the high levels of lactic acid released from the human body, it has been hypothesized to represent a specific human host-recognition cue for anthropophilic (attracted to humans) mosquitoes. Pungent foot odor Most studies use human odors as stimuli to attract host seeking mosquitoes and have reported a strong and significant attractive effect. The studies have found human odor samples very effective in attracting mosquitoes. Foot odors have been demonstrated to have

Symptoms typically begin 10–15 days after the initial mosquito bite, but can occur as late as several months after infection with some P. vivax strains. Travellers taking preventative malaria medications may develop symptoms once they stop taking the drugs. Severe malaria is usually caused by P. falciparum (often referred to as falciparum malaria). Symptoms of falciparum malaria arise 9–30 days after infection. Individuals with cerebral malaria frequently exhibit neurological symptoms, including abnormal posturing , nystagmus , conjugate gaze palsy (failure of
1989-411: A mobile Somali " proto-state " in early 20th-century with fluid boundaries and fluctuating population. It was one of the bloodiest and longest militant movements in sub-Saharan Africa during the colonial era, one that overlapped with World War I. The battles between various sides over two decades killed nearly a third of Somaliland's population and ravaged the local economy. Scholars variously interpret

The Dervish movement attracted between 25,000 and 26,000 youth from different clans over 1899 and 1905, acquired firearms and then attacked the Ethiopian garrison at Jigjiga . The Dervishes were able to take the cattle seized from the local Somalis, giving them their first military victory. The Dervish movement then declared
2223-435: A non-invasive way to detect malarial infections. In addition, these volatile compounds were heavily detected by mosquito antennae as an attractant, making the children more vulnerable to the bite of the mosquitos. Fatty acids Fatty acids have been identified as an attractive compound for mosquitoes, they are typically found in volatile emissions from the skin. These fatty acids that produce body odor profiles originate from
2340-509: A part of miasma theory ; the disease was formerly called ague or marsh fever due to its association with swamps and marshland. The term appeared in English at least as early as 1768. Malaria was once common in most of Europe and North America, where it is no longer endemic, though imported cases do occur. The scientific study of malaria is called malariology. Adults with malaria tend to experience chills and fever—classically in periodic intense bouts lasting around six hours, followed by
2457-530: A period of sweating and fever relief—as well as headache, fatigue, abdominal discomfort, and muscle pain . Children tend to have more general symptoms: fever, cough, vomiting, and diarrhea. Initial manifestations of the disease—common to all malaria species—are similar to flu-like symptoms , and can resemble other conditions such as sepsis , gastroenteritis , and viral diseases . The presentation may include headache , fever , shivering , joint pain , vomiting , hemolytic anemia , jaundice , hemoglobin in

Cerebral malaria is defined as a severe P. falciparum -malaria presenting with neurological symptoms, including coma (with a Glasgow coma scale less than 11, or a Blantyre coma scale less than 3), or with a coma that lasts longer than 30 minutes after a seizure. Methods used to prevent malaria include medications, mosquito elimination and
3978-531: Is insufficient evidence that mosquito repellents can prevent malaria infection. Insecticide-treated nets (ITNs) and indoor residual spraying (IRS) are effective, have been commonly used to prevent malaria, and their use has contributed significantly to the decrease in malaria in the 21st century. ITNs and IRS may not be sufficient to eliminate the disease, as these interventions depend on how many people use nets, how many gaps in insecticide there are (low coverage areas), if people are not protected when outside of

Resistance among the parasites has developed to several antimalarial medications; for example, chloroquine -resistant P. falciparum has spread to most malarial areas, and resistance to artemisinin has become a problem in some parts of Southeast Asia . The disease
4329-400: Is relatively invisible to immune surveillance. However, circulating infected blood cells are destroyed in the spleen . To avoid this fate, the P. falciparum parasite displays adhesive proteins on the surface of the infected blood cells, causing the blood cells to stick to the walls of small blood vessels, thereby sequestering the parasite from passage through the general circulation and

Giving children with anaemia in these areas preventive antimalarial medication improves red blood cell levels slightly but does not affect the risk of death or need for hospitalisation. Vector control refers to methods used to decrease malaria by reducing the levels of transmission by mosquitoes. For individual protection, the most effective insect repellents are based on DEET or picaridin . However, there

However, since HRP2 persists in the blood for up to five weeks after an infection is treated, an HRP2 test sometimes cannot distinguish whether someone currently has malaria or previously had it. Additionally, some P. falciparum parasites in the Amazon region lack the HRP2 gene, complicating detection. RDTs are fast and easily deployed to places without full diagnostic laboratories. However they give considerably less information than microscopy, and sometimes vary in quality from producer to producer and lot to lot. Serological tests to detect antibodies against Plasmodium from

Dervish soldiers used the dhaanto and geeraar traditional dance-song to raise their esprit de corps and sometimes sang it on horseback. Hasan commanded the Dervish movement soldiers in a martial manner, ensuring that they were religiously committed, powered up for warfare and men of character sworn with an oath of allegiance. To ensure unity among his troops, instead of letting them identify themselves by their different tribes, he made them identify themselves uniformly as Dervish. The movement obtained firearms from Sultan Boqor Osman Mahmud of Majerteen Sultanate , as well as

The Dervish movement can thus be seen as a reaction against the establishment of foreign control in Somalia. The Dervish movement was led by a Sufi poet and religious nationalist leader named Mohammed Abdullah Hassan , also known as Sayid Maxamad Cabdulle Xasan . According to Said M. Mohamed, he

After a potential dormant period in the liver, these organisms differentiate to yield thousands of merozoites, which, following rupture of their host cells, escape into the blood and infect red blood cells to begin the erythrocytic stage of the life cycle. The parasite escapes from

The infected red blood cell lyses, and the new merozoites infect new red blood cells, resulting in a cycle that continuously amplifies the number of parasites in an infected person. Over rounds of this infection cycle, a small portion of parasites do not replicate, but instead develop into early sexual stage parasites called male and female " gametocytes ". These gametocytes develop in

Only female mosquitoes feed on blood; male mosquitoes feed on plant nectar and do not transmit
8658-576: The burgeoning Ethiopian realm eastward into the Ogaden territory. In 1884, Britain established a protective authority over Somaliland , aiming to safeguard Aden and the Bab-el-Mandeb strait's strategic interests in the Red Sea. By 1893, following arduous negotiations, an Italian chartered company assumed control over the Benadir coastline in southern Somalia, with the remainder of the region placed under an Italian protectorate in 1889. With foreign rule came
8775-434: The cause, recurrence can be classified as either recrudescence , relapse , or reinfection. Recrudescence is when symptoms return after a symptom-free period due to failure to remove blood-stage parasites by adequate treatment. Relapse is when symptoms reappear after the parasites have been eliminated from the blood but have persisted as dormant hypnozoites in liver cells. Relapse commonly occurs between 8 and 24 weeks after
8892-407: The centralization of the economy, which greatly upset the traditional livestock and pastureland based livelihood of the Somalis. The foreign powers were also all Christians, which created additional suspicions amongst the Somali religious elite. The Ethiopian troops had already proved to be a bane for the Somalis as they were the traditional raiders and plunderers of their grazing herds. The arrival of
9009-518: The coastal regions, leaving the chaotic interior regions in the hands of the Dervishes. During 1905-1910, the Dervishes lost much of their support due to their indiscriminate raids against allies and enemies alike, with several followers subsequently leaving the Dervishes after Hasan was supposedly excommunicated by the head of the Salihiyyah tariqa in Mecca in a famous letter. The First World War shifted
9126-573: The colonial administration in British Somaliland as their enemy. To end the movement, the British sought out the competing Somali clans as coalition partners against the Dervish movement. The British provided these clans with firearms and supplies to fight against the Dervishes. Punitive attacks were launched against Dervish strongholds in 1904. The Dervish movement suffered losses in the field, regrouped into smaller units and resorted to guerrilla warfare . Hasan and his loyalist Dervishes moved into
9243-420: The dawn of July 20, 1920, Haji's army reached Korahe just west of Shineleh where the Dervish and their tribal allies were camped and commenced to attack with them with force. The Dervish-Ogaden numbering 800 were defeated swiftly and only a 100 survived the onslaught and fled south. Haji and his army looted 60,000 livestock and 700 rifles from their defeated foes. During the midst of the battle Haji Warabe entered
9360-500: The defeat of Ethiopian forces . The Dervish movement aimed to remove the British and Italian influence from the region and restore an "Islamic system of governance with a Sufi doctrine as its foundation", according to Mohamed-Rahis Hasan and Salada Robleh. Hassan established a ruling council called the Khususi consisting of Sufi tribal elders and spokesmen, added an adviser from the Ottoman Empire named Muhammad Ali, and thus created
9477-447: The dervish would continue despite the losses across the Somali peninsula until 1920. McNeill notes that by June 1900, Hassan made his position even stronger than before his March 1900 defeat and had "practically dominated the whole of the southern portion of our Protectorate". The British administration started to coordinate with the Italians and Ethiopians, and by 1901 a joint Anglo-Ethiopian force began to coordinate plans to eradicate
9594-521: The development of respiratory distress , which occurs in up to 25% of adults and 40% of children with severe P. falciparum malaria. Possible causes include respiratory compensation of metabolic acidosis , noncardiogenic pulmonary oedema , concomitant pneumonia , and severe anaemia . Although rare in young children with severe malaria, acute respiratory distress syndrome occurs in 5–25% of adults and up to 29% of pregnant women. Coinfection of HIV with malaria increases mortality. Kidney failure
9711-504: The disease in the long run, but the initial costs required are out of reach of many of the world's poorest people. There is a wide difference in the costs of control (i.e. maintenance of low endemicity) and elimination programs between countries. For example, in China—whose government in 2010 announced a strategy to pursue malaria elimination in the Chinese provinces —the required investment is
9828-578: The disease is common. Occasional doses of the combination medication sulfadoxine/pyrimethamine are recommended in infants and after the first trimester of pregnancy in areas with high rates of malaria. As of 2023, two malaria vaccines have been endorsed by the World Health Organization . The recommended treatment for malaria is a combination of antimalarial medications that includes artemisinin . The second medication may be either mefloquine , lumefantrine , or sulfadoxine/pyrimethamine. Quinine , along with doxycycline , may be used if artemisinin
9945-469: The disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. The mosquito vector is itself harmed by Plasmodium infections, causing reduced lifespan. Human malaria is caused by single-celled microorganisms of the Plasmodium group. It
10062-462: The disease. Females of the mosquito genus Anopheles prefer to feed at night. They usually start searching for a meal at dusk, and continue through the night until they succeed. However, in Africa, due to the extensive use of bed nets, they began to bite earlier, before bed-net time. Malaria parasites can also be transmitted by blood transfusions , although this is rare. Symptoms of malaria can recur after varying symptom-free periods. Depending upon
10179-453: The emergence and demise of the militant Dervish movement in Somalia. Some consider the "Sufi Islamic" ideology as the driver, others consider economic crisis to the nomadic lifestyle triggered by the occupation and "colonial predation" ideology as the trigger for the Dervish movement, while post-modernists state that both religion and nationalism created the Dervish movement. According to Abdullah A. Mohamoud, traditional Somali society followed
10296-494: The eyes to turn together in the same direction), opisthotonus , seizures , or coma . Diagnosis based on skin odor profiles Humans emanate a large range of smells. Studies have been conducted on how to detect human malaria infections through volatile compounds from the skin - suggesting that volatile biomarkers may be a reliable source for the detection of infection, including those asymptomatic. Using skin body odor profiles can be efficient in diagnosing global populations, and
10413-702: The founder of modern Somali nationalism, while some others view it as an ambitious Muslim brotherhood militancy that destroyed Somalia's opportunity to move towards modernization and progress in favor of a puritanical Islamic state embedded with Islamic education – ideas enshrined in the contemporary constitution of Somalia. Yet others such as Aidid consider the Dervish legacy was one of cruelty and violence against those Somalis who disagreed with or refused to submit to Hasan. These Somalis were "declared infidels" and Dervish soldiers were ordered by Hasan to "kill them, their children and women and snatch all their property", according to Shultz and Dew. Another legacy that came out of
10530-442: The frequency with which malaria parasites complete their life cycle in the cell. Individuals who are homozygous (with two copies of the abnormal haemoglobin beta allele ) have sickle-cell anaemia , while those who are heterozygous (with one abnormal allele and one normal allele) experience resistance to malaria without severe anaemia. Although the shorter life expectancy for those with the homozygous condition would tend to disfavour
10647-401: The gun's return, while Hasan replied that the British should leave the country, a sentiment he had previously claimed in 1897 when he declared himself "the leader of a sovereign nation". Hasan continued to preach against the British introduction of Christianity to Somalia, stating that the "British infidels have destroyed our [Islamic] religion and made our children their children". Hasan left
10764-526: The heart of Mogadishu . These were for three major Somali History icons: Mohammed Abdullah Hassan of the Dervish movement, Stone Thrower and Hawo Tako . The Dervish period spawned many war poets and peace poets involved in a struggle known as the Literary war which had a profound effect on Somali poetry and Literature , with Mohammed Abdullah Hassan featuring as the most prominent poet of that Age. The flag of Khatumo , designed by Rooda Xassan features
10881-399: The highest attractiveness to anthropophilic mosquitoes. Some of these studies have included traps that had been baited with nylon socks previously worn by human participants and were deemed efficient in catching adult mosquitos. Foot odors have high numbers of volatile compounds, which in turn elicit an olfactory response from mosquitoes. Malaria has several serious complications , including
10998-429: The home, and an increase in mosquitoes that are resistant to insecticides. Modifications to people's houses to prevent mosquito exposure may be an important long term prevention measure. Mosquito nets help keep mosquitoes away from people and reduce infection rates and transmission of malaria. Nets are not a perfect barrier and are often treated with an insecticide designed to kill the mosquito before it has time to find
11115-423: The infection of red blood cells. Symptoms develop once there are more than around 100,000 parasites per milliliter of blood. Many of the symptoms associated with severe malaria are caused by the tendency of P. falciparum to bind to blood vessel walls, resulting in damage to the affected vessels and surrounding tissue. Parasites sequestered in the blood vessels of the lung contribute to respiratory failure . In
11232-502: The initial symptoms and is often seen in P. vivax and P. ovale infections. P. vivax malaria cases in temperate areas often involve overwintering by hypnozoites, with relapses beginning the year after the mosquito bite. Reinfection means that parasites were eliminated from the entire body but new parasites were then introduced. Reinfection cannot readily be distinguished from relapse and recrudescence, although recurrence of infection within two weeks of treatment ending
11349-634: The liver undetected by wrapping itself in the cell membrane of the infected host liver cell. Within the red blood cells, the parasites multiply further, again asexually, periodically breaking out of their host cells to invade fresh red blood cells. Several such amplification cycles occur. Thus, classical descriptions of waves of fever arise from simultaneous waves of merozoites escaping and infecting red blood cells. Some P. vivax sporozoites do not immediately develop into exoerythrocytic-phase merozoites, but instead, produce hypnozoites that remain dormant for periods ranging from several months (7–10 months
11466-431: The metabolism of glycerol, lactic acid, amino acids, and lipids - through the action of bacteria found within the skin. They create a “chemical signature” for the mosquitoes to locate a potential host, humans in particular. Lactic acid Lactic acid, a naturally produced levorotatory isomer, has been titled an attractant of mosquitoes for a long time. Lactic acid is predominantly produced by eccrine-sweat glands, creating
11583-504: The modified haemoglobin S molecules are exposed to low amounts of oxygen, or crowd together due to dehydration, they can stick together forming strands that cause the cell to distort into a curved sickle shape. In these strands, the molecule is not as effective in taking or releasing oxygen, and the cell is not flexible enough to circulate freely. In the early stages of malaria, the parasite can cause infected red cells to sickle, and so they are removed from circulation sooner. This reduces
11700-513: The nephew of Mohammed Abdullah Hassan who was named by him, to wage his own 1945 Sheikh Bashir Rebellion together with Habr Je'lo tribesmen against the British authorities in Somaliland . The Dervish legacy in Somalia and Somaliland has been influential. It was the "most important revivalist Islamic movements" in Somalia, state Hasan and Robleh. The movement and particularly its leader has been controversial among Somalis. Some cherish it as
11817-603: The offending tribes would be punished by their respective governments. The Abyssinians only nominally having control over the Haud failed to meet their end of the agreement and this resulted in the Dervish and Ogaden alliance raiding with impunity while the Isaaq and Dhulbahante were unable to avenge the raids due to the British Camel Corps restraining them and returning looted Ogaden livestock. The secretary administrator of British Somaliland, Douglas James Jardine noted that
11934-583: The original Arabic script into Italian by the incumbent Governatori della Somalia , the British are described taking twenty-seven garesas or 27 houses from the Dhulbahante clan. His letter to the Bimal was documented as the most extended exposition of his mind as a Muslim thinker and religious figure. The letter is until this day still preserved. It is said that the Bimal thanks to their size being numerically powerful, traditionally and religiously devoted fierce warriors and having possession of much resources have intrigued Mahamed Abdulle Hassan. But not only that
12051-624: The parasite eventually disappears from that area, as happened in North America, Europe, and parts of the Middle East. However, unless the parasite is eliminated from the whole world, it could re-establish if conditions revert to a combination that favors the parasite's reproduction. Furthermore, the cost per person of eliminating anopheles mosquitoes rises with decreasing population density, making it economically unfeasible in some areas. Prevention of malaria may be more cost-effective than treatment of
12168-451: The prevention of bites. As of 2023, there are two malaria vaccines , approved for use in children by the WHO: RTS,S and R21 . The presence of malaria in an area requires a combination of high human population density, high Anopheles mosquito population density and high rates of transmission from humans to mosquitoes and from mosquitoes to humans. If any of these is lowered sufficiently,
12285-556: The prolonged struggle and violence between the colonial powers and the Dervish movement, according to Abdullah A. Mohamoud, was the arming of the Somali clans followed by decades of destructive clan-driven militarism , violent turmoil, and high human costs well after the demise of the Dervish movement. Hasan and his Dervish movement have inspired a nationalistic following in contemporary Somalia. The military government of Somalia led by Mohamed Siad Barre , for example, erected statues visible between Makka Al Mukarama and Shabelle Roads in
12402-411: The richest (71%) and the poorest (53%) households. Malaria is usually confirmed by the microscopic examination of blood films or by antigen -based rapid diagnostic tests (RDT). Microscopy—i.e. examining Giemsa -stained blood with a light microscope —is the gold standard for malaria diagnosis. Microscopists typically examine both a "thick film" of blood, allowing them to scan many blood cells in
12519-437: The screening and monitoring of infection to officially eradicate malaria. Research findings have predominantly relied on chemical explanations to explain the differences in attractiveness among humans based on distinct odor profiles. The existence of volatile compounds, like fatty acids, and lactic acid is an essential reason on why some individuals are more appealing to mosquitos than others. Volatile compounds Kanika Khanna,
12636-563: The spleen. The blockage of the microvasculature causes symptoms such as those in placental malaria. Sequestered red blood cells can breach the blood–brain barrier and cause cerebral malaria. Due to the high levels of mortality and morbidity caused by malaria—especially the P. falciparum species—it has placed the greatest selective pressure on the human genome in recent history. Several genetic factors provide some resistance to it including sickle cell trait , thalassaemia traits, glucose-6-phosphate dehydrogenase deficiency , and
12753-526: The time anyway), a white turban, a tasbih (or rosary), and a rifle." In March 1900, Hassan along with his dervish forces attacked an Ethiopian outpost near Jijiga . Capt. Malcolm McNeill who commanded the Somali Field Force against Hassan reported that the Dervish were completely defeated, and that they have suffered a heavy loss amounting to 2,800 killed, according to the Ethiopians. Similar raids by
12870-605: The trait's survival, the trait is preserved in malaria-prone regions because of the benefits provided by the heterozygous form. Liver dysfunction as a result of malaria is uncommon and usually only occurs in those with another liver condition such as viral hepatitis or chronic liver disease . The syndrome is sometimes called malarial hepatitis . While it has been considered a rare occurrence, malarial hepatopathy has seen an increase, particularly in Southeast Asia and India. Liver compromise in people with malaria correlates with
12987-520: The urban settlement and moved to preach in the countryside. His influence spread in the rural parts and many elders, as well as youth, became his followers. Hasan converted the influenced youth from different clans into a Muslim brotherhood, rallying to protect Islam from the influence of the Christian missionaries. These formed Hasan's armed resistance group set to confront the colonial powers, and came to be known as Dervishes or Daraawiish , states Said M. Mohamed. The Dervish movement temporarily created
13104-415: The urine with kidney failure may occur. Complications may include spontaneous bleeding, coagulopathy , and shock . Malaria during pregnancy can cause stillbirths , infant mortality , miscarriage , and low birth weight , particularly in P. falciparum infection, but also with P. vivax . Malaria is caused by infection with parasites in the genus Plasmodium . In humans, malaria
13221-424: The urine , retinal damage , and convulsions . The classic symptom of malaria is paroxysm —a cyclical occurrence of sudden coldness followed by shivering and then fever and sweating, occurring every two days ( tertian fever ) in P. vivax and P. ovale infections, and every three days ( quartan fever ) for P. malariae . P. falciparum infection can cause recurrent fever every 36–48 hours, or
13338-401: The vast majority of malaria deaths), P. vivax , and P. knowlesi (a simian malaria that spills over into thousands of people a year). P. ovale and P. malariae generally cause a milder form of malaria. Malaria is typically diagnosed by the microscopic examination of blood using blood films , or with antigen-based rapid diagnostic tests . Methods that use
13455-427: The world where malaria is common were protected by an ITN. That number increased to 20.3 million (18.5%) African children using ITNs in 2007, leaving 89.6 million children unprotected and to 68% African children using mosquito nets in 2015. The percentage of children sleeping under ITNs in sub-Saharan Africa increased from less than 40% in 2011 to over 50% in 2021. Most nets are impregnated with pyrethroids ,
13572-660: Was born in Sacmadeeqo sometime between 1856 and 1864 to a father who was a religious teacher. He studied in Somali Islamic seminaries and later went on Hajj to Mecca where he met Shaykh Muhammad Salah of the Salihiya Islamic Tariqah , which states The Encyclopedia Britannica was a "militant, reformist, and puritanical Sufi order". The preachings of Salah to Hasan had roots in Saudi Wahhabism , and it considered it
13689-447: Was espoused until 1910 when its founder in Mecca denounced the Dervish via a letter. Nonetheless, some authors trivialized the role of religion: out of the twenty-seven forts built by the Dervish, not a single one of them had a mosque constructed within them, which according to one colonial official placed doubt that there was a religious impulse behind Dervish statehood. The general consul of
