How a failed foreign invasion transformed a fringe youth militia into a dominant insurgency.
The 2006 Ethiopian invasion of Somalia was intended to stabilize the region, but it backfired spectacularly. Instead of empowering the government, the occupation fueled a massive insurgency, turning al-Shabaab from a small youth group into a powerful, territory-holding force that continues to shape the conflict today.
The current phase of the Somali Civil War, which began in 2009, is rooted in the aftermath of the 2006 Ethiopian National Defense Force (ENDF) invasion. Backed by the United States, this intervention ousted the Islamic Courts Union (ICU) from power, but the resulting military occupation lacked legitimacy and public support. By 2008, the Transitional Federal Government (TFG) was on the brink of collapse, with over 80% of its police and army having deserted. The insurgency, led by the newly independent al-Shabaab, successfully forced an Ethiopian withdrawal by November 2008.
The Ethiopian retreat in early 2009 did not bring peace. Instead, it triggered a power struggle among various Islamist factions. Al-Shabaab, which had grown from roughly 600 fighters to several thousand during the occupation, rejected a power-sharing deal between the TFG and the Alliance for the Re-liberation of Somalia. By 2010, al-Shabaab reached its peak operational capacity, absorbing rival groups like Hizbul Islam and pledging allegiance to al-Qaeda in 2012. The conflict shifted from a conventional war to a complex insurgency involving African Union peacekeeping forces (AMISOM), Kenyan military operations, and targeted U.S. drone strikes.
Despite losing major urban strongholds like Mogadishu in 2011 and Kismayo in 2012, al-Shabaab remains a potent force. The group has pivoted toward guerrilla warfare and terror attacks, maintaining influence in rural areas of southern Somalia. While the Federal Government of Somalia was formed in 2012 to provide a new political foundation, the conflict persists. Recent years have seen the emergence of the Islamic State in Somalia and new regional tensions, such as the 2023 Las Anod conflict, demonstrating that the war remains a fluid and multifaceted struggle for control.
