The aftermath of the Houthi takeover in Yemen refers to developments following the Houthis' takeover of the Yemeni capital of Sana'a and dissolution of the government, which eventually led to a civil war and the Saudi Arabian-led intervention in Yemen.
The Battle of Aden was a battle for the control of Aden, Yemen, between Houthis rebels and Yemen Army forces loyal to Ali Abdullah Saleh on one side, and Yemen Army units loyal to Abdrabbuh Mansur Hadi and Southern Movement militias on the other side.
On 26 March 2015, Saudi Arabia, leading a coalition of nine countries from West Asia and North Africa, launched an intervention in Yemen following a new joint request from Yemeni president Abdrabbuh Mansur Hadi for military support after his forces were ousted from Sanaʽa by Houthi insurgents during the Yemeni Civil War. Government forces, Houthi rebels, and other armed groups fought after the draft constitution and power-sharing arrangements collapsed, despite progress made by the UN during the political transition at that time. Violence escalated in mid-2014. Houthis and allied insurgents seized control of Sana'a in September 2014 and thereafter. In response, President Hadi asked Saudi Arabia to intervene against the Iranian-backed Houthis.
The Battle of Dhale was a key fight for control of Dhale, Yemen, between the Houthis and Yemen Army units loyal to Ali Abdullah Saleh on one side, and militiamen and Yemen Army units loyal to Abd Rabbuh Mansur Hadi on the other side.
The Shabwah campaign was a campaign for control of the Shabwah Governorate of Yemen, between the Houthis and Yemen Army units loyal to Ali Abdullah Saleh on one side, and militiamen and Yemen Army units loyal to Abdrabbuh Mansur Hadi on the other side. The offensive was also launched during a previously started AQAP offensive.
The Lahij insurgency was a guerrilla war in 2015 waged by tribesmen loyal to Abdrabbuh Mansur Hadi against the Houthis and Yemen Army units loyal to Ali Abdullah Saleh, who controlled most of the Lahij Governorate of Yemen. In late July, Pro-Hadi forces had launched an offensive to recapture Al Anad Air Base and rest of Lahij Governorate. On 4 August, Pro-Hadi forces had retaken full control of the Lahij Governorate.
The siege of Taiz is an ongoing, protracted military confrontation between opposing Yemeni forces in the city of Taiz for control of the city and surrounding area. The battle began one month after the start of the Yemeni Civil War.
In early December 2015, two Yemeni towns, Zinjibar and Ja'ar, were captured by the jihadist group Al-Qaeda in the Arabian Peninsula (AQAP). This was the second capture and occupation of Zinjibar during unrest in Yemen. The town was earlier taken by AQAP's in May 2011 and held until the summer of 2012.
The Aden unrest was a conflict between Islamist factions, such as al-Qaeda in the Arabian Peninsula, and Islamic State of Iraq and the Levant's Yemen Branch, against the loyalists of president Abd Rabbuh Mansur Hadi and later to conflict between UAE-backed and Saudi-backed factions within the coalition. In 2017, fighting also broke out between factions aligned with different members of the Saudi-led coalition namely Saudi Arabia-backed Abdrabbuh Mansur Hadi and Al-Islah and UAE-backed separatist Southern Transitional Council and Southern Movement.

The Marib campaign, also called Marib offensive, is an ongoing military campaign taking place in the Yemeni civil war for the control of the Marib Governorate of Yemen. Fighting between the Houthi forces and factions of the Yemeni Army loyal to Supreme Political Council on one side, and Yemeni Army units loyal to president Abdrabbuh Mansur Hadi and militiamen on the other side, took place since early 2015. Marib is rich in oil and gas resources and is a key strategic governorate because it connects the Houthi-controlled Sanaa and Alimi-controlled Hadhramaut governorates.
The Abyan conflict was a series of clashes between forces of AQAP loyal to Yemeni president Abdrabbuh Mansur Hadi, and forces loyal to Southern Movement for the control of Abyan between 2016 and 2018.
The Southern Yemen clashes were a series of clashes in the city of Aden between the pro-Hadi government troops backed by Saudi Arabia and Southern Transitional Council forces backed by the United Arab Emirates. The Southern Transitional Council took control of Aden and Zinjibar.
The Battle of Marib is an ongoing battle that erupted since February 2021 following the advance of the Houthis towards the city of Marib, the capital of Marib Governorate in Yemen controlled by the Cabinet of Yemen.
In August 2022, forces of Yemen's Emirati-backed separatist Southern Movement, mainly represented by the Southern Transitional Council, launched an offensive in the Abyan and Shabwah provinces. Initially, the Southern forces mostly fought against Saudi-backed government forces, most of which belonged to the armed wing of the Islah party. Since early September 2022, however, the Southern Movement's offensive has become more focused on battling local al-Qaeda strongholds.
