18.12 Al-Shabaab (2006)
Al-Shabaab means “the Youth.” Al-Shabaab is a Somali Islamist militant group that emerged around 2006, during Somalia’s long period of civil war, weak governance, and state collapse.
Somalia was already overwhelmingly Muslim long before Al-Shabaab existed and Islam is Somalia’s official religion. However, Al-Shabaab’s ideology is more extreme than the Islamic Courts Union, and is at odds with the Sufi-influenced Islam practiced by many Somalis.
To understand Al-Shabaab, it is important to understand Somalia’s recent history.
In 1991, Somalia’s central government collapsed after the fall of Siad Barre. For years afterward, the country was marked by warlordism, political fragmentation, violence, and humanitarian crisis. This instability created the kind of environment in which extremist movements could grow.
Al-Shabaab emerged out of the militant youth wing of the Islamic Courts Union (ICU), a network of Islamic courts and militias that briefly gained control over much of southern Somalia in 2006. Later that year, Ethiopian forces, backed by the United States, intervened to support Somalia’s Transitional Federal Government. This intervention helped radicalize Al-Shabaab further and made it a central part of the armed resistance.
Al-Shabaab represents a regional jihadist insurgency. Unlike Al-Qaeda, which developed as a more explicitly transnational network, Al-Shabaab grew out of Somalia’s local collapse and conflict. At the same time, it later tied itself to the broader Al-Qaeda movement, making it both a local insurgency and part of a wider jihadist network.
The group became known for suicide bombings, assassinations, raids, extortion, and attacks on civilians, as well as attacks on Somali government forces and African Union troops. In areas under its control, it has imposed a harsh interpretation of Islamic law.
Al-Shabaab has survived for so long because it embedded itself in local conditions. It has exploited weak governance, clan grievances, poverty, and humanitarian crisis, while also raising money through taxation, extortion, and smuggling. This helped it remain durable even after repeated military campaigns against it.
Although rooted in Somalia, Al-Shabaab has also carried out major attacks in neighboring countries, especially Kenya, showing that its violence extends beyond Somalia’s borders. This makes it more than a purely local insurgency, even though it did not begin as a global movement like Al-Qaeda.
In August 2024, Al-Shabaab attacked Lido Beach in Mogadishu, killing 37 civilians and injuring more than 200. This was one of their deadliest attacks in years and serves as a potent modern example of their tactics.
As of 2026, Al-Shabaab remains one of the most resilient jihadist groups in Africa. It currently operates an extensive shadow governance and taxation system, including managing a centralized taxation system that generates more revenue in some areas than the federal government—often by taxing businesses in government-held cities like Mogadishu. It is therefore important not just as a historical example, but as a continuing force in East African conflict and Islamist extremism.
Al-Shabaab shows how state failure, regional war, Islamist ideology, and affiliation with Al-Qaeda can combine to produce a long-lasting extremist insurgency.
In section 18.13, we will examine the Taliban (1994), a movement that emerged from Afghanistan’s post-Soviet withdrawal chaos, and developed into a state-controlling Islamist force rather than a primarily regional insurgent network.
