Al-Shabaab was founded in
Las Anod in 2003. During that same year, the American
Central Intelligence Agency began covert operations targeting the
Islamic Courts Union (ICU) by backing anti-ICU Somali warlords with the aim of preventing the formation of a '
Taliban like' state in Somalia that could provide haven to
al-Qaeda. In 2005, Mogadishu was hit by a significant wave of unexplained
assassinations and disappearances. The Islamic Courts claimed that covert US government operations and warlords were targeting high ranking ICU officials. According to C. Barnes & H. Hassan, "It was in this context that a military force known as Al-Shabaab ('the Youth') emerged, related to but seemingly autonomous of the broad based Courts movement." Contrary to many reports, Al-Shabaab was neither the armed wing of the Islamic Courts Union nor its most important military component. Al-Shabaab fighters operated as the youth wing of the Courts' militia and gained a fierce reputation during the war against the CIA-backed
Somali warlord alliance in Mogadishu in early to mid-2006, distinguishing themselves within the ICU's military wing.
2006–2009: Ethiopian invasion region during the Ethiopian
military occupation (15 July 2008) Al-Shabaab rose to prominence and radicalized following the full scale Ethiopian invasion of Somalia during December 2006. At the time, Al-Shabaab was about six hundred fighters strong. The invasion resulted in the deaths of many Islamic Courts Union affiliates, leaving a vacuum for the small group of several hundred youth that served as the ICU's Shabaab militia to gain prominence. During the
military occupation the group garnered popular support from across many segments of Somali society, as Al-Shabaab was widely viewed as a genuine resistance movement against the Ethiopian military occupation; despite its inclinations towards hardline interpretations of Islam. Though the invasion had fractured the
Islamic Courts Union, it galvanized
non-ethnic religious Islamic nationalism on which Al-Shabaab capitalized, especially for recruitment purposes, with thousands of new recruits drawn to the group. Many ordinary citizens had been
radicalized by the US-backed Ethiopian invasion, enabling Al-Shabaab to firmly embed itself in the regions social, economic and political environment. According to Cocodia, "Al-Shabaab from an objective standpoint is the response of an unlawfully deposed regime employing all means possible to reclaim the authority that was wrenched from it." In the initial years, many Somalis perceived Al-Shabaab as disciplined, orderly, and fair, which earned the group significant legitimacy. However, this perception was later lost due to their arbitrary rulings. However, this move came too late to have a substantial impact on the group's transformation into a formidable oppositional force. Military pressures on the group were sustained into 2013.
Drought, Al-Qaeda, and internal struggle Some Al-Shabaab members viewed the 2010 Ramadan offensive as disastrously ill-conceived, and subsequent territorial losses galvanised internal opposition to the leadership of
Ahmed Abdi Godane, who was publicly named the group's emir in December 2007. As
a severe drought afflicted the region, critics, generally associated with the leadership of
Hassan Dahir Aweys and
Mukhtar Robow, opposed Al-Shabaab's response to the resulting famine, particularly its obstruction of foreign
humanitarian aid to populations in its territories . More broadly, they argued that the group's authoritarian style of governance, and use of violence, were causing the group to lose public support. Some suggested that these leadership missteps were the result of Godane's lack of clan roots, which they said led him to undervalue the lives both of civilians and of Al-Shabaab fighters. These criticisms became intertwined with a broader and pre-existing dispute over the increasingly globalist flavour of Al-Shabaab's ideology – Godane was among the faction which viewed Somalia as only one battleground of global jihad. Godane's announcement in February 2012 of a merger with
al-Qaeda thus also met opposition. Other senior Al-Shabaab members met at a conference in Baidabo, and outlined a policy programme which diverged from Godane's: they rejected Godane's proposal to change the group's name to Al-Qaeda in East Africa, and resolved to focus on domestic issues rather than global jihad. They also resolved to establish a regional shura of Islamic clerics, independent of Al-Qaeda control. Godane's rival Aweys declared publicly that "Al-Shabaab and Al-Qaeda are merely a small part of the larger Islamic group and Al-Qaeda's ideology should not be viewed as the sole, righteous path for Islam." during a joint operation between Somali forces and AMISOM, May 2014 In 2013, these internal rifts led to internecine violence as Godane effected what was virtually a
purge of his critics. Among those killed were
Ibrahim al-Afghani and three other senior commanders, executed in June; and
Omar Hammami, killed in September. Journalist
Simon Tisdall viewed the September 2013
Westgate shopping mall shooting in
Nairobi, Kenya as a reflection of the internal power struggle, with Godane's hardline globalist faction seeking to exert its authority.
Defections From mid-to-late 2011, and into 2012, Al-Shabaab faced an increasing number of defections. It was not the first such wave of defections: in particular, in late 2009, after the Ethiopian departure from Somalia, several leaders had defected to the Somali government, citing complaints about Al-Shabaab's use of
suicide attacks and executions; its "false interpretations of Islam"; and its use of
extortion and attitude towards foreign humanitarian aid. Such defections were viewed as strategically important to Al-Shabaab's adversaries, not only for their propaganda use but because former militants could provide intelligence about Al-Shabaab's combat strategy. However, according to the AMISOM and the Somali government, the volume of defections in the period around 2012 was unprecedented, and indicated that Al-Shabaab's cohesion and authority were deteriorating: in June 2012, the government said that around 500 Al-Shabaab militants had already defected to it, and that more were doing so every day. Al-Shabaab brutalities, which alienated local populations, were again cited as central in motivating defections. On September 5 and September 22, 2012, two large contingents of Al-Shabaab fighters – around 200 each time – surrendered to the government coalition in Afmadow and Garsale respectively. Another wave of defections and desertions followed Godane's 2013 purges – Aweys, for example, fled the group in mid-2013. Al-Shabaab increasingly avoided direct military combat and large battles, in favour of "dictat[ing] the conflict's pace by undertaking smaller ambushes at locations of its own choosing". The group undertook high-profile attacks outside Somalia such as the
Westgate shopping mall attack by four militants left 67 dead - the deadliest attack in Kenya since the
1998 US embassy bombings in Nairobi. That death-toll was exceeded two years later in the Garissa University College attack in which 148 people were killed in an attack targeting Christian students. Furthermore, two sophisticated attempts to target airliners were observed in 2016. In February a device in a laptop bag that had passed screening was detonated mid-flight, killing only the bomber, and in March another laptop bomb exploded during screening. Reacting to apparent advances in the group's bomb-making capabilities, the UN Security Council later prohibited the transfer of bomb components to Somalia. The group has also developed a strategy of maintaining a "semi-territorial presence" in key regions and parts of key cities: while it no longer had exclusive and military authority over substantial territory, it retained a sporadic presence, and therefore significant influence, in many places. Nonetheless, by 2016, Al-Shabaab was viewed as significantly weakened by the military campaign against it, with earlier losses compounded in 2014–15 by
Operation Indian Ocean, a joint endeavour by the AMISOM, the Somali government, and the United States. Reports of further senior defections continued into 2015. Moreover, an
American drone strike killed Godane on September 1, 2014; he was succeeded as Al-Shabaab leader by
Ahmad Diri, who took office the same week. Other senior members were killed in armed clashes or by American drone strikes in 2014 and 2015. According to some reports, since Godane's death, the group has placed less weight on global jihad than on local grievances.
2018–2022: Resurgence In October 2017, more than 500 people were killed by
a suicide truck bombing in Mogadishu, including many children, provoking domestic and international outrage. Al-Shabaab did not claim responsibility for the attack but was suspected of involvement. In December 2019,
another suicide truck bomb marked the beginning of a series of Al-Shabaab attacks on the capital city, which continued into 2022. Al-Shabaab also targeted American military personnel in
an attack on a Kenyan base in January 2020. By 2020, the group's strategy of semi-territorialism allowed it operate freely in much of rural Somalia, with its primary base in the
Jubba River Valley, although air strikes against its leaders continued; and it has recently won military successes against the government. It had also expanded its operations in Puntland, prompting a military offensive by Puntland forces in 2021. As of July 2022, Al-Shabaab is generally considered to be "resurgent", a situation partly enabled by a reduction in the number of American air strikes, and possibly motivated by competition with
Islamic State in Somalia, which has been conducting its own expansionary campaign. On 20 July 2022,
Al-Shabaab launched an invasion into Ethiopia's
Somali Region. Taking advantage of the ongoing
Tigray War, the goal of the operation was to establish a presence for the group within southern
Ethiopia. The incursion began with over a thousand Al-Shabaab fighters staging diversionary attacks on four
Ethiopian-Somali border towns in order to allow a force of 500 to 800 fighters to penetrate the Ethiopian security zone and advance into the region, who then advanced 150 km into the region. After two weeks of intense clashes and airstrikes, the ENDF and the Somali Region security forces began to reassert control. A
battalion of around 500 Al-Shabaab fighters succeeded in evading the Ethiopian army and reached its main target, the
Bale Mountains.
2022–2024: Escalation In August 2022, Somali President Hassan Sheikh Mohamud declared "total war" against Al-Shabaab during a televised address after the group carried out a deadly
hotel attack in Mogadishu and also announced that the Somalia military had regained territory from Al-Shabaab in the central Galmudug state and the Southwest state. By September 2022 Somali and the
ATMIS offensive operations against Al-Shabaab, with U.S. support, would escalate to the highest point in five years. The operation, which is considered a combined Somali-ATMIS offensive, On 20 September 2022, as the military operation progressed, a statement was released by the Somali Ministry of Information which revealed that President Sheikh would not offer any other option than surrender for Al-Shabaab members. On 29 October 2022, Al-Shabaab took responsibility for
a twin car bombing that occurred in Mogadishu targeting the
Ministry of Education. The attacks killed 121 people and injured 333, making it the deadliest at the time since 2017. On 26 May 2023, Al-Shabaab claimed responsibility for
an attack that reportedly killed 137 soldiers in the
Buulo Mareer base, just south-west of the capital Mogadishu. Meanwhile, the Ugandan President
Yoweri Museveni stated that the number is closer to 54 African Union peacekeepers stationed in Somalia. In December 2024, the UN Security Council approved a resolution to establish the
African Union Support and Stabilization Mission in Somalia (AUSSOM), a streamlined successor to the
African Union Transition Mission in Somalia (ATMIS), which ends in 2024. The AUSSOM will deploy up to 12,626 personnel to support Somalia's fight against the Al-Shabaab insurgency. On 26 December 2024, the militant group of Al-Shabaab confirmed the death of Mohamed Mire Jama, a senior leader of the group, who had been designated as a terrorist by the
United States, in an American
drone strike near
Kunyo Barrow of the
Lower Shabelle region in the
South West State of Somalia.
2025–present: Military offensive In early 2025, Al-Shabaab launched a large-scale military
offensive, capturing dozens of towns and vast areas of territory. In its most ambitious operation in years, the group's ultimate objective is to seize
Mogadishu and overthrow the federal government. Probing attacks that began in January escalated into major offensives on multiple fronts, stretching government troops and auxiliary clan militias to their breaking point. By April the military situation had deteriorated to the extent that waves of rumors were circulating on
social media of an impending insurgent assault on the capital. While this did not occur, an attack was carried out on the
motorcade of Somali President
Hassan Sheikh Mohamud while it was driving through the city.
Airstrikes by international actors and sporadic local
counterattacks have slowed the advance. According to
The Telegraph, as the group has gained major ground this year, Al-Shabaab has sought to implement a "
hearts and minds" strategy, aiming to shed its reputation for repression and for carrying out suicide bombings that frequently kill civilians. Large-scale and indiscriminate
suicide attacks in Mogadishu, once capable of killing hundreds, have largely ceased. Analysts have compared the campaign to the
Taliban's 2021 offensive in
Afghanistan, noting that Al-Shabaab and the
Taliban are "very structurally, militarily and ideologically similar." The internationally recognized governments of both Somalia and Afghanistan have been described by observers as products of the
war on terror, plagued by
corruption, predatory governance, and low public legitimacy. == Propaganda strategy ==
