War in Iraq (2013–2017) in the context of "2012–2013 Iraqi protests"

Christianity, which originated in the Middle East during the 1st century AD, is a significant minority religion within the region, characterized by the diversity of its beliefs and traditions, compared to Christianity in other parts of the Old World. Today, Christians make up approximately 5% of the Middle Eastern population, down from 13-20% in the early 20th century. Cyprus is the only Christian majority country in the Middle East, with Christians forming between 76% and 78% of the country's total population, most of them adhering to Eastern Orthodox Christianity. Lebanon has the second highest proportion of Christians in the Middle East, around 40%, predominantly Maronites. After Lebanon, Egypt has the next largest proportion of Christians (predominantly Copts), at around 10% of its total population. Copts of Egypt, numbering around 10 million, constitute the single largest Christian community in the entire Middle East.

The Eastern Aramaic speaking Assyrians of northern Iraq, northeastern Syria, southeastern Turkey, and parts of Iran have suffered due to ethnic cleansing, religious discrimination, and persecution for many centuries. During the 20th century, the percentage of Christians in the Middle East fell mainly as a result of the late Ottoman genocides: the Armenian genocide, Greek genocide, and Assyrian genocide committed against them by the Ottoman Turks and their allies, leading many to flee and congregate in areas in northern Iraq, northeastern Syria, North America, and Western Europe. The great majority of Aramaic speaking Christians are followers of the Assyrian Church of the East, Chaldean Catholic Church, Syriac Orthodox Church, Ancient Church of the East, Assyrian Pentecostal Church and Assyrian Evangelical Church. In Iraq, the numbers of Christians has declined to between 300,000 and 500,000 (from 0.8 to 1.4 million before 2003 US invasion). Assyrian Christians were between 800,000 and 1.2 million before 2003. In 2014, the population of the Nineveh Plains in northern Iraq was scattered to Dohuk, Erbil and Jordan due to ISIS forcing the Assyrian community out of their historical homeland, but since the defeat of the Islamic State in 2017, Christians have slowly began returning.

The Arab Spring (Arabic: الربيع العربي, romanized: ar-rabīʻ al-ʻarabī) was a series of pro-democracy anti-government protests, uprisings, and armed rebellions that spread across much of the Arab world in the early 2010s. It began in Tunisia in response to the death of Mohamed Bouazizi by self-immolation. From Tunisia, the protests initially spread to five other countries: Libya, Egypt, Yemen, Syria and Bahrain. Rulers were deposed: Zine El Abidine Ben Ali of Tunisia, Muammar Gaddafi of Libya, and Hosni Mubarak of Egypt, all in 2011; and Ali Abdullah Saleh of Yemen in 2012. Omar al-Bashir of Sudan was deposed in 2019 after a coup d'état caused by a revolution. Bashar al-Assad of Syria was deposed in December 2024 after 13 years of civil war. Major uprisings and social violence occurred, including riots, civil wars, or insurgencies. Sustained street demonstrations took place in Morocco, Iraq, Algeria, Lebanon, Jordan, Kuwait, Oman and Sudan. Minor protests took place in Djibouti, Mauritania, Palestine, Saudi Arabia and the Western Sahara. A major slogan of the demonstrators in the Arab world is ash-shaʻb yurīd isqāṭ an-niẓām! (Arabic: الشعب يريد إسقاط النظام, lit. 'the people want to bring down the regime').

The wave of initial revolutions and protests faded by mid to late 2012, as many Arab Spring demonstrations were met with violent responses from authorities, pro-government militias, counterdemonstrators, and militaries. These attacks were answered with violence from protesters in some cases. Multiple large-scale conflicts followed: the Syrian civil war; the rise of ISIS, insurgency in Iraq and the following civil war; the Egyptian Crisis, election and removal from office of Mohamed Morsi, and subsequent unrest and insurgency; the Libyan Crisis; and the Yemeni crisis and subsequent civil war. Regimes that lacked major oil wealth and hereditary succession arrangements were more likely to undergo regime change.

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 invasion of Iraq, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian civil war. 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 2025, IS has been contained to a small area and force capability.

In mid-June 2014, Iran, according to American and British information, started flying drones over Iraq, and, according to Reuters, Iranian soldiers were in Iraq fighting IS. Simultaneously, the United States ordered a small number of troops to Iraq and started flying crewed aircraft over Iraq. In July 2014, according to the International Institute for Strategic Studies, Iran sent Sukhoi Su-25 aircraft to Iraq, and Hezbollah purportedly sent trainers and advisers to Iraq in order to help Shia militias to monitor IS's movements. In August 2014, the US and Iran separately began a campaign of airstrikes on IS targets in Iraq. Since then, fourteen countries in a US-led coalition have also executed airstrikes on IS in Iraq and in Syria. Starting from September 2014, United States began closely co-operating with Saudi Arabia and Jordan to wage a co-ordinated aerial bombing campaign against IS targets across Iraq and Syria.

The 2017 Western Iraq campaign was the final major military operation of the 2013–2017 war in Iraq, in the western province of Anbar, and on the border with Syria, with the goal of completely expelling IS forces from their last strongholds in Iraq.

The offensive followed the Hawija offensive by the Iraqi Government, and was also concurrent with several major offensives in Syria: the Syrian Democratic Forces' Deir ez-Zor offensive, and the Syrian Government's Battle of Deir ez-Zor and Eastern Syria campaign on the opposite side of the Al-Qa'im border crossing.

The Iraqi conflict is a series of violent events that began with the 2003 American-led invasion of Iraq and deposition of Iraqi president Saddam Hussein, followed by a series of conflicts including the protracted Iraq War (2003–2011), the Iraqi insurgency (2011–2013), the War in Iraq (2013–2017), and most recently, the small-scale Islamic State insurgency in 4 provinces located in Northern Iraq since 2017.

In the ensuing 2003–2011 Iraq War, the Multi-National Force (MNF–I) led by the United States helped to establish a Shia-dominated federal government, which was soon opposed by an Iraqi insurgency. Insurgent groups mostly fought the new government and MNF-I, but also each other, mostly along sectarian lines between Shias and Sunnis. In 2011, the MNF–I withdrew from Iraq, leading to renewed sectarian violence and enabling the emergence of the Islamic State (IS). The renewed war drew an American-led intervention in 2014. The most recent war in the country came to a close in 2017 as the Iraqi government and its allies largely defeated the IS, which was followed by a low-level IS insurgency in certain rural northern parts of the country.

Military advisors or combat advisors are military personnel deployed to advise on military matters. The term is often used for soldiers sent to foreign countries to aid such countries' militaries with their military education and training, organization, and other various military tasks.

Foreign powers or organizations may send such soldiers to support countries or insurgencies while minimizing the risks of potential casualties and avoiding the political ramifications of overtly mobilizing military forces to aid an ally.

The Iraqi civil war was a short armed conflict from 2006 to 2008 between various sectarian Shia and Sunni armed groups, such as the Islamic State of Iraq and the Mahdi Army, in addition to the Iraqi government alongside American-led coalition forces. In February 2006, the insurgency against the coalition and government escalated into a sectarian civil war after the bombing of Al-Askari Shrine, considered a holy site in Twelver Shi'ism. US President George W. Bush and Iraqi officials accused Al-Qaeda in Iraq (AQI) of orchestrating the bombing. AQI publicly denied any links. The incident set off a wave of attacks on Sunni civilians by Shia militants, followed by attacks on Shia civilians by Sunni militants.

The UN Secretary General stated in September 2006 that if patterns of discord and violence continued, the Iraqi state was in danger of breaking up. On 10 January 2007, Bush said that "80% of Iraq's sectarian violence occurs within 30 miles (48 km) of the capital. This violence is splitting Baghdad into sectarian enclaves, and shakes the confidence of all Iraqis." By late 2007, the National Intelligence Estimate described the conflict as having elements of a civil war. In 2008, during the Sunni Awakening and the U.S. troop surge, violence declined dramatically. However, an insurgency by ISI continued to plague Iraq following the U.S. withdrawal in late 2011. In June 2014, the Islamic State of Iraq and the Levant, the successor to Islamic State of Iraq, launched a major military offensive against the Iraq government and declared a self-proclaimed worldwide Islamic caliphate. This led to another full-scale war from 2013 to 2017, in which the government declared victory.

Throughout the 20th century, Iraq witnessed multiple periods of instability and conflict that prompted the creation and flight of many refugees. Earlier examples include the exodus of Iraqi Jews and the flight of Iraqi Kurds. The Iraqi invasion of Iran in 1980 and the ensuing Iran–Iraq War (1980–1988) triggered a deterioration of ties among the country's various ethnic and religious communities, and also exacerbated in violent events like the Ba'athist Arabization campaigns in northern Iraq (1968–2003), which led to the killing and displacement of thousands of minorities. The Iraqi invasion of Kuwait (1990) and the ensuing Gulf War (1990–1991), which ended with Iraq's defeat and the application of United Nations sanctions (1991–2003), also resulted in the creation of many Iraqi refugees. It was not until the beginning of the ongoing Iraqi conflict, however, that sustained waves of Iraqi refugees would be created, numbering in the millions: the 2003 invasion of Iraq and the ensuing Iraq War (2003–2011) killed and displaced hundreds of thousands of Iraqis, both internally and externally, and the later War in Iraq (2013–2017) forced even more people to flee from the country. Many Iraqi refugees established themselves in urban areas of other countries rather than in refugee camps.

In April 2007, there were approximately four million Iraqi refugees around the world, including: 1.9 million within Iraq; two million in neighbouring Arab countries, as well as in Iran and Turkey; and approximately 200,000 outside of the Middle East entirely. The United Nations High Commissioner for Refugees (UNHCR) has led the humanitarian efforts for Iraqi refugees. The number of displaced persons and refugees from the Iraqi conflict is considered to be the largest in the Middle East, though this figure may now be lower than that of the refugees of the Syrian civil war.
