Marib campaign (2020–2021) was a major offensive during the Yemeni Civil War (2014–present) centered on the oil-rich Ma'rib Governorate and the city of Ma'rib. The campaign involved sustained clashes between the Houthis and forces loyal to Abdrabbuh Mansur Hadi, backed by the Saudi Arabian-led coalition. It drew international attention from actors such as United Nations, United States, United Kingdom, and regional powers including Iran and United Arab Emirates.
The campaign followed the collapse of the Riyadh Agreement dynamics and renewed offensives after the Battle of Sanaa (2014–2015) and the fall of Aden to Southern Transitional Council tensions. Ma'rib, as the last major northern stronghold of the Hadi administration and home to the Ma'rib gas fields and the Marib Dam, had strategic importance for control after the Battle of Al-Anad Air Base and the Taiz campaign (2015–present). International mediation efforts such as UN Special Envoy to Yemen initiatives and talks in Riyadh and Geneva intersected with battlefield developments influenced by the Arab Coalition air campaign and reports of Iranian support to the Ansar Allah through links to Islamic Revolutionary Guard Corps proxies and Hezbollah advisers.
On one side were forces aligned with Abdrabbuh Mansur Hadi including units of the Yemeni Army, elements from Ali Mohsen al-Ahmar's brigades, tribal militias from the Al-Jawf Governorate, and units supported by the Saudi Arabian-led coalition, including assets from the United Arab Emirates and coordination with the Southern Transitional Council. Key pro-Hadi commanders included regional military figures and tribal leaders such as Mansour Thawaba and other local sheikhs. Opposing them were the Houthis under Abdul-Malik al-Houthi's political leadership with battlefield commanders drawn from Houthi leadership and allied military cadres. External patrons named in reporting included Iran, alleged to provide weapons and ballistic technology, and groups with ties to Hezbollah providing training. International actors such as the United States Department of State, United Nations Security Council, and European Union monitored and occasionally commented on the conduct of commanders and belligerents.
The offensive intensified in 2020 as the Ansar Allah launched coordinated attacks from positions in Saada Governorate, Al Jawf Governorate, and Sana'a Governorate toward Ma'rib. Heavy fighting followed near the Sahn Al-Jin oil field and the approaches to Ma'rib city, including battles around the Marib Dam, Majzer and Rahbah districts. The fall of surrounding districts like Raghwan and repeated assaults on the city perimeter led to waves of displacement toward Al-Jawf and Aden. The Saudi-led coalition escalated airstrikes targeting Houthi supply lines and positions, while ground combat featured offensives and counteroffensives through 2020 and into 2021. Notable incidents included aircraft strikes affecting UN-run facilities and clashes that involved armored formations and artillery exchanges near Marib Gas Field infrastructure. The campaign saw fluctuating frontlines, ceasefire attempts tied to diplomatic tracks involving the UN Special Envoy to Yemen, and intermittent prisoner exchanges referencing protocols seen in other battles such as the Battle of Taiz and the Battle of Aden.
Combatants used combined-arms tactics including infantry assaults, mechanized columns with T-62 and BMP variants, and improvised explosive devices resembling patterns from the Iraq War and Syrian Civil War. The Houthis employed ballistic missiles, Badr-1-type rockets, and drones similar to models reported in Libya conflict (2011–present) and Nagorno-Karabakh conflict (2020), with alleged supply chains from Iran and procurement routes via Gulf of Aden arms smuggling. The Saudi Arabian-led coalition relied on F-15 and Typhoon-class strike aircraft, close air support, and reconnaissance assets from partners like the United States Air Force and Royal Air Force. Urban warfare in Marib city featured snipers, mortars, and tunnel networks that paralleled tactics used in battles such as Battle of Mosul (2016–2017) and Siege of Aleppo (2012–2016). Electronic warfare and information operations by actors tied to Al Jazeera and Al Arabiya shaped narratives around battlefield successes and losses.
The offensive precipitated a humanitarian emergency monitored by United Nations Office for the Coordination of Humanitarian Affairs and NGOs like Médecins Sans Frontières and International Committee of the Red Cross. Hundreds of thousands of civilians were internally displaced toward Aden and Sana'a Governorate suburbs, straining camps administered by groups such as UNHCR and World Food Programme. Hospitals in Ma'rib faced shortages of medical supplies due to disruptions affecting WHO supply lines, while outbreaks of disease and malnutrition echoed crises in Hodeidah and Taiz. Casualty figures reported in media and by the United Nations cited thousands of combatant deaths and significant civilian tolls, with damaged infrastructure including Ma'rib Dam-adjacent facilities and oil installations reducing fuel supplies and affecting humanitarian logistics. Allegations of violations of international humanitarian law were raised to the UN Human Rights Council and the International Criminal Court was referenced in advocacy by human rights organizations.
By late 2021 the campaign left Ma'rib contested, altering calculations for the Hadi administration and the Ansar Allah ahead of diplomatic initiatives such as UN-led peace talks and regional shifts including rapprochement moves involving Saudi Arabia and Iran. Control of Ma'rib Governorate influenced revenue from the Marib Gas Field and access to strategic routes between Sana'a and Aden, affecting bargaining positions in negotiations reminiscent of arrangements after the Sanaa Agreement and other ceasefire accords. The campaign informed international policy debates in capitals like Washington, D.C., London, Riyadh, and Tehran about arms transfers, sanctions, and mediation, while its tactics presaged later operations in the Yemeni Civil War (2014–present). The legacy included prolonged displacement managed by UNHCR and reconstruction challenges comparable to post-conflict recovery seen after the Gulf War and the Syrian Civil War.
