How the Houthis evolved from a local movement to a Red Sea power

The brief in 4 cards

1. Context1 / 4
   • The Houthis, officially known as Ansar Allah, emerged from a Zaidi Shia revivalist movement in northern Yemen during the 1990s.
   • The movement became an armed insurgency after fighting with Yemen’s government began in 2004.
   • The Houthis captured much of Sana’a in 2014 and later became a major actor in Yemen’s civil war.
   • Their influence now extends beyond Yemen through missiles, drones and operations affecting Red Sea shipping.
   • In September 2026, the UN reported intensified fighting as Houthi forces advanced towards the Bab el-Mandeb area.
2. Key highlights2 / 4

   Local origins: The movement initially focused on preserving Zaidi religious and cultural identity in northern Yemen.

   Political evolution: Opposition to Yemen’s government developed into a sustained armed insurgency.

   Territorial power: Control of Sana’a and other areas enabled the Houthis to become more than a local insurgent movement.

   Military capability: The group developed missile, drone and maritime capabilities that can affect targets far beyond its original base.

   Iran relationship: Iran provides important support, but analysts also describe significant Houthi operational autonomy.

   Red Sea importance: Presence near Bab el-Mandeb gives the group influence around a major route linking the Red Sea with the Gulf of Aden.

3. Key concepts3 / 4
   1. Non-state armed actor

   • An organised armed group that is not the regular military of a recognised state. Such groups may control territory, collect revenue and develop military capabilities.
   • Some influence regional politics without being internationally recognised as governments.

   News connection: The Houthis gained territorial, political and military influence beyond their original local base.

   2. Asymmetric warfare

   • Asymmetric warfare occurs when opponents have very different military strengths and methods. A weaker actor may rely on drones, missiles, mobile forces and attacks on vulnerable infrastructure.
   • These methods can impose high costs without matching a stronger opponent’s conventional forces.

   News connection: Houthi missile, drone and maritime capabilities influence regional security despite limited conventional power.

   3. Maritime chokepoint

   • A maritime chokepoint is a narrow sea passage through which large volumes of shipping must travel. Bab el-Mandeb connects the Red Sea with the Gulf of Aden.
   • Ships using the Suez Canal between Europe and the Indian Ocean normally pass through this route.

   News connection: Military activity near Bab el-Mandeb can create risks for shipping far beyond Yemen.

   4. Proxy versus strategic alignment

   • A proxy usually implies an actor operating largely on behalf of an external sponsor. Strategic alignment means actors share interests and cooperate while retaining different priorities and some independent decision-making.
   • The Houthis are often called an Iranian proxy, but their relationship involves support, dependency and Houthi autonomy.

   News connection: Iranian influence does not automatically mean complete control over Houthi decisions.

4. Way forward4 / 4

   Protect navigation: Regional and international actors can strengthen maritime monitoring while keeping commercial sea routes open.

   Prevent escalation: Diplomatic channels and UN-led negotiations remain important for limiting wider regional conflict.

   Address Yemen’s conflict: A lasting reduction in Red Sea tensions also requires progress towards a political settlement inside Yemen.
