These are some of the notable events relating to politics in 2015.
2015 (MMXV) was a common year starting on Thursday of the Gregorian calendar, the 2015th year of the Common Era (CE) and Anno Domini (AD) designations, the 15th year of the 3rd millennium and the 21st century, and the 6th year of the 2010s decade.
Many states began to intervene against the Islamic State, in both the Syrian Civil War and the War in Iraq (2013–2017), in response to its rapid territorial gains from its 2014 Northern Iraq offensives, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian Civil War. These efforts are called the war against the Islamic State, or the war against ISIS. In later years, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. All these efforts significantly degraded the Islamic State's capabilities by around 2019–2020. While moderate fighting continues in Syria, as of 2024, ISIS has been contained to a manageably small area and force capability.
The Military of the Islamic State is the fighting force of the Islamic State (IS). The total force size at its peak was estimated from tens of thousands to over two hundred thousand. IS's armed forces grew quickly during its territorial expansion in 2014. The IS military, including groups incorporated into it in 2014, openly operates and controls territory in multiple cities in Libya and Nigeria. In October 2016, it conquered the city of Qandala in Puntland, Somalia. It conquered much of eastern Syria and western Iraq in 2014, territory it lost finally only in 2019. It also has had border clashes with and made incursions into Lebanon, Iran, and Jordan. IS-linked groups operate in Algeria, Pakistan, the Philippines, and in West Africa. In January 2015, IS was also confirmed to have a military presence in Afghanistan and in Yemen.
The Islamic State (IS) had its core in Iraq and Syria from 2013 to 2017 and 2019 respectively, where the proto-state controlled significant swathes of urban, rural, and desert territory, mainly in the Mesopotamian region. Today the group controls scattered pockets of land in the area, as well as territory or insurgent cells in other areas, notably Afghanistan, West Africa, the Sahara, Somalia, Mozambique, and the Democratic Republic of the Congo. As of 2023, large swathes of Mali have fallen under IS control.

On 26 March 2015, Saudi Arabia, leading a coalition of nine countries from West Asia and North Africa, launched an intervention in Yemen at the request of Yemeni president Abdrabbuh Mansur Hadi, who had been ousted from the capital, Sanaa, in September 2014 by Houthi insurgents during the Yemeni Civil War. Efforts by the United Nations to facilitate a power sharing arrangement under a new transitional government collapsed, leading to escalating conflict between government forces, Houthi rebels, and other armed groups, which culminated in Hadi fleeing to Saudi Arabia shortly before it began military operations in the country.
International reactions to the Saudi-led intervention in Yemen of 2015 were mixed. Most other Arab League nations and several Western governments backed the Saudi Arabia-led military coalition, but other governments warned against an escalation in the violent situation in Yemen.
On 26 June 2015, attacks occurred in France, Kuwait, and Tunisia, one day following a deadly massacre in Syria. The day of the attacks was dubbed "Bloody Friday" by Anglophone media and "Black Friday" among Francophone media in Europe and North Africa.
Operation Martyr Yalçın was a military operation conducted by the Turkish Air Force against Islamic State of Iraq and the Levant (ISIL) positions in Syria, and Kurdistan Workers' Party (PKK) positions in northern Iraq, on 24 and 25 July 2015.

Iran and Saudi Arabia are engaged in an ongoing struggle for influence in the Middle East and other regions of the Muslim world. The two countries have provided varying degrees of support to opposing sides in nearby conflicts, including the civil wars in Syria and Yemen; and disputes in Bahrain, Lebanon, Qatar, and Iraq. The struggle also extends to disputes or broader competition in other countries globally including in West, North and East Africa, South, Central, Southeast Asia, the Balkans, and the Caucasus.
The Islamic State – Yemen Province is a branch of the militant Islamist group Islamic State (IS), active in Yemen. IS announced the group's formation on 13 November 2014.
War crimes and human rights violations, committed by all warring parties, have been widespread throughout the Yemeni civil war. This includes the two main groups involved in the ongoing conflict: forces loyal to the current Yemeni president, Abdrabbuh Mansur Hadi, and Houthis and other forces supporting Ali Abdullah Saleh, the former Yemeni president. Al-Qaeda in the Arabian Peninsula and the Islamic State of Iraq and the Levant have also carried out attacks in Yemen. The Saudi-led coalition, backed by the United States and other nations, has also been accused of violating human rights and breaking international law, especially in regards to airstrikes that repeatedly hit civilian targets.
The following is a timeline of the Yemeni civil war, which began in September 2014.
The Qatar–Saudi Arabia diplomatic conflict refers to the ongoing struggle for regional influence between Qatar and the Kingdom of Saudi Arabia (KSA), both of which are members of the Gulf Cooperation Council (GCC). It is sometimes called the New Arab Cold War. Bilateral relations have been especially strained since the beginning of the Arab Spring, that left a power vacuum both states sought to fill, with Qatar being supportive of the revolutionary wave and Saudi Arabia opposing it. Both states are allies of the United States, and have avoided direct conflict with one another.
The US intervention in the Syrian civil war is the United States-led support of Syrian opposition and the Federation of Northern Syria during the course of the Syrian Civil War and active military involvement led by the United States and its allies — the militaries of the United Kingdom, France, Jordan, Turkey, Canada, Australia and more — against the Islamic State of Iraq and the Levant (ISIL) and al-Nusra Front since 2014. Since early 2017, the U.S. and other Coalition partners have also targeted the Syrian government and its allies via airstrikes and aircraft shoot-downs.
During the Yemeni civil war, Saudi Arabia led an Arab coalition of nine nations from the Middle East and parts of Africa in response to calls from the internationally recognized pro-Saudi president of Yemen Abdrabbuh Mansur Hadi for military support after he was ousted by the Houthi movement due to economic and political grievances, and fled to Saudi Arabia.
