Houthi movement

The Houthi movement, which calls itself Ansar Allah, is a Zaydi Shiite political and armed organization originating in northern Yemen. It emerged from religious and social activism in the 1990s and developed into an insurgent force. In 2014, its fighters seized the capital, Sanaa, and displaced the internationally recognized government. The movement has since controlled much of northern Yemen while fighting a civil war involving domestic factions and foreign powers.

The Houthis combine religious revivalism, Yemeni nationalism and armed opposition to the United States, Israel and Saudi Arabia. Their leadership has built governing institutions in territory under its control, while maintaining an extensive military structure. They have fought the Yemeni government and a Saudi-led coalition, and have launched missiles and drones toward regional states. Since late 2023, they have attacked commercial shipping in the Red Sea and claimed these operations support Gaza.

The movement’s armed activity has caused civilian casualties and disrupted regional trade. Its authorities have detained political opponents, journalists, aid workers and members of religious minorities. Reports describe restrictions on women and girls, recruitment of children and diversion of humanitarian assistance. Iran has provided material and technical support, although the degree of command it exercises over Houthi decisions is debated. These facts make the movement both a local power in Yemen and a regional security actor.

History and background

The Houthis emerged from the Zaydi community of northern Yemen. Zaydism is a branch of Shiite Islam with its own legal and theological tradition, distinct from Iran’s Twelver Shiism. Zaydi imams ruled parts of Yemen for centuries before the 1962 revolution ended the imamate and established a republic. The political and religious changes that followed reshaped the region and contributed to a sense among some Zaydis that their traditions and institutions were being marginalized.

In the 1990s, Hussein Badreddin al-Houthi and other activists organized religious and educational activity in Saada province. The movement sought to revive Zaydi learning and oppose the influence of Saudi-backed Salafi institutions. It also criticized government corruption and American policy in the region. Its supporters built youth organizations and study groups that became known as the Believing Youth.

The movement’s name derives from the al-Houthi family, whose members became its prominent leaders. The organization was initially a religious and social movement rather than a military force. Its transformation into an insurgency followed clashes with the Yemeni government and the killing of Hussein al-Houthi by government forces in 2004. His death became a rallying point and deepened the movement’s hostility toward the government.

From 2004 to 2010, the Houthis fought six rounds of conflict with the Yemeni state, known as the Saada wars. The fighting caused deaths, displacement and destruction in the north. The government accused the movement of seeking to restore the imamate and destabilize the republic; Houthi leaders said they were defending Zaydi rights and resisting repression. Saudi forces intervened in 2009 after the conflict crossed the border, further regionalizing the confrontation.

The Arab Spring protests of 2011 weakened Yemen’s government and changed the political balance. President Ali Abdullah Saleh left office under a transition arrangement, and a national dialogue sought to redesign the state. The Houthis expanded their territory and political influence, opposing the proposed federal map and the transition’s leadership. Their forces allied tactically with Saleh, their former adversary, against the government of President Abdrabbuh Mansur Hadi.

In September 2014, Houthi forces seized Sanaa after protests and clashes. They took control of ministries and security institutions and pressured the government. In January 2015, they placed Hadi under house arrest and dissolved parliament. Hadi fled to Aden and later Saudi Arabia. The takeover dismantled the transition process and prompted a military intervention by a Saudi-led coalition in March 2015.

Yemeni civil war and political control

The war expanded into a complex conflict involving the Houthis, the internationally recognized government, southern separatists, tribal groups, jihadist organizations and foreign powers. Saudi Arabia and the United Arab Emirates supported different anti-Houthi forces, while Iran backed the Houthi movement. The coalition conducted airstrikes and imposed restrictions on access to Yemen. The Houthis launched missiles and cross-border attacks at Saudi territory. Civilians suffered from bombardment, displacement, disease and the collapse of public services.

In December 2017, the alliance between the Houthis and Saleh ended violently. Saleh announced that he would seek a new relationship with the coalition; Houthi forces killed him after fighting in Sanaa. The episode showed the movement’s ability to dominate the capital and eliminate a former partner. It also removed a political figure with extensive networks in the armed forces and state bureaucracy.

The Houthis consolidated a governing administration in Sanaa and other northern areas. Their authorities collect taxes, regulate commerce, appoint officials and maintain security forces. The administration is not internationally recognized as Yemen’s national government. It has used coercive power against opponents and independent civic organizations. The internationally recognized government remains based outside the capital and has struggled to establish authority across the country.

Houthi governance combines formal ministries with a parallel supervisory system linked to the movement. Security and intelligence bodies monitor political activity. Authorities have restricted demonstrations and public criticism, and have arrested journalists, academics and activists. Some detainees have faced prolonged imprisonment and unfair proceedings. The group presents these measures as protection against espionage and foreign interference; rights organizations describe them as repression.

The movement’s internal institutions also include religious and educational bodies. Its leadership has promoted a narrative of resistance and Zaydi identity. Schools and public events have incorporated the organization’s political messaging. This has allowed the Houthis to influence civic life in areas under their control, while critics say the system imposes an ideological program and limits pluralism.

Ideology, religion and political outlook

The Houthis draw on Zaydi religious traditions and Yemeni political history. Their leaders describe the movement as defending the faith, national sovereignty and communities in the north. The group’s political doctrine has evolved during warfare and state-building. It combines opposition to foreign intervention with a claim that the al-Houthi leadership has a special religious and political role.

Houthi ideology has been influenced by Iranian revolutionary politics, but Zaydism is not identical to Iran’s Twelver religious system. The movement has developed ties with Iran and adopted some revolutionary symbols and rhetoric. Its leaders frame the relationship as solidarity among forces resisting United States and Israeli policies. Analysts have debated how much the movement’s doctrine reflects indigenous Yemeni politics and how much it has been shaped by foreign assistance.

The movement’s slogan includes antisemitic and anti-American language and calls for violence against Israel. The anti-Jewish component invokes collective blame and a religiously framed hostility toward Jews, rather than criticism confined to a government’s actions. This rhetoric has been criticized as antisemitic and contributes to the movement’s international isolation. The group’s leaders argue that their slogans express opposition to foreign policy, but the wording and associated propaganda go beyond policy critique.

The Houthis reject the legitimacy of the internationally recognized government and have not accepted a political settlement that would require them to surrender their weapons or authority in Sanaa. Negotiations have addressed ceasefires, access, salaries and governance arrangements. The group has used military strength to improve its bargaining position. A durable settlement would need to address the interests of Yemen’s other communities and establish credible institutions beyond Houthi control.

Organization and leadership

Abdul-Malik al-Houthi has been the movement’s principal leader since his brother Hussein’s death. He exercises ideological and political authority and communicates through speeches and statements. The organization’s senior structure includes military, political, security and administrative bodies. Details of internal appointments and command are not fully public, and some figures operate from outside the country.

The movement’s armed forces developed from local fighters into a larger military organization. It captured equipment from the Yemeni state and expanded its capabilities through training, production and external support. Its forces include infantry, missile units, drones, naval elements and security services. Estimates of personnel and weapons vary, and the group does not publish independently verifiable figures.

The Houthis have built local networks through tribal alliances, religious institutions and administrative appointments. Their reach depends on both coercion and negotiated accommodation with local leaders. Some communities support the movement because of shared identity or opposition to foreign intervention; others comply because the group controls security and public resources. Local variation is significant, so it is inaccurate to treat northern Yemen as politically uniform.

The movement has promoted new leaders and commanders during the war. Family ties and loyalty to the organization have been important in appointments. Critics describe the structure as dynastic and exclusionary, while supporters emphasize continuity and unity during wartime. The concentration of power around the al-Houthi leadership limits independent decision-making within areas under its control.

Military capabilities and tactics

The Houthis use conventional and asymmetric tactics. Their forces have conducted ground offensives, built defensive positions, employed improvised explosive devices and used snipers and artillery. They have also developed missiles and unmanned aerial vehicles capable of striking distant targets. Some equipment has been captured from Yemen’s military; other systems contain Iranian-origin components or reflect Iranian technical assistance.

Missile and drone attacks have targeted Saudi Arabia, the United Arab Emirates and ships in regional waters. The movement has claimed strikes on airports, oil facilities, military bases and commercial vessels. Some attacks caused deaths and damage; others were intercepted or failed to reach their targets. Attribution and assessment require independent evidence, because the group and its adversaries often issue conflicting claims.

From 2015 onward, the Houthis launched repeated cross-border attacks into Saudi Arabia. These included ballistic missiles and drones aimed at cities and infrastructure. Saudi air defenses intercepted many incoming weapons, but attacks caused civilian casualties and heightened regional tensions. The coalition’s air campaign also killed civilians and damaged infrastructure in Yemen. Both sides faced scrutiny for compliance with the laws of armed conflict.

In late 2023, the Houthis began attacks on commercial shipping in the Red Sea, asserting that vessels connected to Israel or its partners were legitimate targets. The attacks used missiles, drones and attempts to board or seize ships. Vessels of multiple nationalities were threatened or struck, and some crews were killed or taken hostage. The United States and its partners launched strikes against Houthi military sites. The campaign disrupted one of the world’s major shipping routes and raised insurance and transport costs.

The attacks on shipping formed part of the Red Sea crisis and a broader effort to link the Yemen conflict to the war in Gaza. The Houthis announced that they would target vessels associated with Israel, but their targeting was not limited consistently to Israeli-owned ships. Merchant crews and civilian shipping were exposed to danger. Under international law, attacks on commercial vessels require a valid military target and must comply with distinction and proportionality.

Iranian support has contributed to Houthi missile and drone capabilities. United Nations experts and foreign governments have reported transfers of weapons components, training and technical knowledge. The Houthis have also developed local production and adaptation capabilities. Evidence of Iranian support does not automatically prove that Tehran directs each attack; the relationship includes assistance and shared interests, while operational decision-making remains a contested question.

Human rights and treatment of civilians

Human rights organizations have documented arbitrary detention, torture, unfair trials and restrictions on freedom of expression by Houthi authorities. The group has detained journalists, political opponents, members of religious minorities and employees of international organizations. Some detainees have faced accusations of espionage or collaboration without transparent evidence. The Houthis have denied wrongdoing and said they are protecting the country from foreign operations.

The movement has been accused of recruiting and using children in armed activity. Children have appeared in training camps and military propaganda. International law prohibits recruiting children under 15 and requires heightened protection for all persons under 18. The use of children exposes them to injury and death and undermines their right to education and a safe childhood.

Women and girls have faced restrictions on movement, employment and public participation in Houthi-controlled areas. Authorities have imposed requirements for male guardians to accompany women on travel and have targeted women’s rights activists. Members of the Baháʼí community have faced arrests and pressure, while the historic Jewish community in Yemen has nearly disappeared amid decades of emigration, conflict and discrimination. These policies and acts have drawn condemnation from international organizations.

The conflict has also generated allegations of diversion of humanitarian aid. Humanitarian organizations have reported interference, restrictions on access and demands for control over aid distribution. The Houthis say international agencies have politicized assistance and that their authorities must regulate operations. Diversion or obstruction can deprive civilians of food and medicine and violate obligations to facilitate humanitarian relief.

Yemen’s civilian crisis has resulted from multiple causes, including war, economic collapse, restrictions on imports, disease and the destruction of infrastructure. Houthi actions have contributed through repression, attacks and obstruction, while coalition operations and government failures have also caused harm. Attributing responsibility requires specific evidence; recognizing multiple parties’ conduct does not excuse any party’s violations.

Foreign relations and support

The Houthis have maintained close relations with Iran. Iranian support has included weapons, training and technical assistance, according to United Nations and government assessments. The movement and Iran share opposition to Israel, Saudi Arabia and United States influence, but their relationship is not equivalent to a formal command chain. The Houthis have their own leadership, territorial base and domestic objectives.

The IRGC has been linked to the transfer of missile and drone technology and support for the movement. Iran has denied responsibility for Houthi attacks and has described the group as an independent Yemeni actor. Analysts point to evidence of Iranian-origin systems and training, while acknowledging uncertainty about direct control. The movement’s relationship with Iran is both a source of military capability and a subject of strategic interpretation.

Relations with Saudi Arabia have shifted between open warfare and negotiations. A United Nations-brokered truce in 2022 reduced cross-border attacks and created space for talks, though it did not resolve the conflict. Saudi and Houthi representatives later engaged in direct discussions about ceasefire terms and economic arrangements. The war in Gaza and attacks on shipping complicated the prospects for a broader settlement.

The Houthis have criticized Western governments and attacked international shipping, leading to military responses from the United States and the United Kingdom. The United States redesignated the group under a terrorism-related sanctions category in 2024 and later changed its legal designation. Canada also listed Ansarallah as a terrorist entity. Designations affect financial transactions and diplomacy, though exemptions may exist for humanitarian activity.

Governance and public opinion

Public attitudes toward the movement vary. Some Yemenis support it as a force resisting foreign intervention and defending northern communities. Others oppose its seizure of power, religious policies and repression. In areas under Houthi control, open opposition can be dangerous, making public opinion surveys difficult to conduct. Expressions of support at rallies do not provide a complete measure of political consent.

The movement’s governance has persisted through wartime because it controls the capital and key institutions, maintains armed forces and draws revenue from taxation and trade. Its authorities have paid some public employees irregularly and have faced criticism for diverting resources to military activity. The internationally recognized government has had its own legitimacy and administrative challenges, contributing to fragmented state authority.

A negotiated settlement would need to address the distribution of power, weapons, public revenues and regional autonomy. The Houthis have demanded recognition of their role and a share in national institutions. Other Yemeni factions have resisted a political arrangement that leaves the movement’s armed forces outside state command. These disagreements remain central barriers to ending the war.

Assessment

The Houthi movement has transformed from a northern religious revival organization into a governing and military power with regional reach. It seized the capital, survived a long air campaign and developed missile and drone capabilities that affect neighboring states and international shipping. Its capacity reflects local mobilization, captured state resources and external assistance.

The movement’s military achievements have not resolved Yemen’s political divisions or delivered stable governance. Its rule has involved coercion, restrictions on civic freedoms and serious human rights allegations. Its attacks on shipping have endangered civilian crews and disrupted global trade. The Houthis’ claim to resist foreign intervention must be weighed against their own use of force against Yemenis and targets beyond Yemen.

Future outcomes will depend on domestic negotiations, regional diplomacy, the flow of Iranian support and the willingness of the movement to accept limits on its armed authority. A durable peace requires protection for civilians, political inclusion and accountable state institutions. The Houthis remain a central actor in any settlement, but they are not the only party whose decisions determine Yemen’s future.
