The Islamic State of Iraq (ISI; Arabic: دولة العراق الإسلامية‎ Dawlat al-ʿIrāq al-ʾIslāmiyyah) (commonly referred to as al-Qaeda in Iraq) was a Sunni Islamic group that aimed to establish an Islamic state in Sunni, Arab-majority areas of Iraq. It was formed on 15 October 2006 from the merger of a number Iraqi insurgent groups, including Tanzim Qaidat al-Jihad fi Bilad al-Rafidayn—‘Al-Qaeda in Iraq’—and its Mujahideen Shura Council allies.

In 2006–2008, during the Iraq War, ISI had military units or strongholds in Mosul and in the governorates of Baghdad, Al Anbar and Diyala, and they claimed Baqubah as their capital.

In April 2013, ISI transformed itself into Islamic State of Iraq and the Levant (ISIL, ISIS, IS), which is still active today.

Iraq (/ɪˈræk/, ⁱ/ɪˈrɑːk/, or /aɪˈræk/; Arabic: العراق‎ al-‘Irāq, Kurdish: Êraq), officially the Republic of Iraq (Arabic:  جمهورية العراق  Jumhūrīyat al-‘Irāq; Kurdish: كۆماری عێراق‎ Komar-i ‘Êraq), is a country in Western Asia. The country borders Turkey to the north, Iran to the east, Kuwait to the southeast, Saudi Arabia to the south, Jordan to the southwest, and Syria to the west. The southern part of Iraq is within the Arabian Peninsula. The capital, Baghdad, is in the centre of the country and its largest city. The largest ethnic groups in Iraq are Arabs and Kurds. Other ethnic groups include Assyrians, Turkmen, Shabakis, Yazidis, Armenians, Mandeans, Circassians, and Kawliya. Around 95% of the country's 36 million citizens are Shia or Sunni Muslims, with Christianity, Yarsan, Yezidism, and Mandeanism also present.

Iraq has a narrow section of coastline measuring 58 km (36 mi) on the northern Persian Gulf and its territory encompasses the Mesopotamian Alluvial Plain, the northwestern end of the Zagros mountain range, and the eastern part of the Syrian Desert. Two major rivers, the Tigris and Euphrates, run south through the centre of Iraq and flow into the Shatt al-Arab near the Persian Gulf. These rivers provide Iraq with significant amounts of fertile land.

An Islamic state (Arabic: الدولة الإسلامية‎ ad-dawlah al-islāmiyah) is a type of government primarily based on the application of shari'a (Islamic law), dispensation of justice, maintenance of law and order. From the early years of Islam, numerous governments have been founded as "Islamic."

However, the term "Islamic state" has taken on a more specific connotation since the 20th century. The concept of the modern Islamic state has been articulated and promoted by ideologues such as Ayatollah Ruhollah Khomeini, Israr Ahmed, and Sayyid Qutb. Like the earlier notion of the caliphate, the modern Islamic state is rooted in Islamic law. It is modeled after the rule of Muhammad. However, unlike caliph-led governments which were imperial despotisms or monarchies (Arabic: malik), a modern Islamic state can incorporate modern political institutions such as elections, parliamentary rule, judicial review, and popular sovereignty.

Today, many Muslim countries have incorporated Islamic law, wholly or in part, into their legal systems. Certain Muslim states have declared Islam to be their state religion in their constitutions, but do not apply Islamic law in their courts. Islamic states which are not Islamic monarchies are usually referred to as Islamic republics.

Islamic state is a type of government based on Islamic religious law (sharia).

Islamic state may also refer to:

Islamic State of Iraq and the Levant (ISIL, IPA /ˈaɪsᵻl/), alternatively translated as Islamic State of Iraq and Syria or Islamic State of Iraq and al-Sham (ISIS, /ˈaɪsᵻs/), is a Salafi jihadist militant group that follows an Islamic fundamentalist, Wahhabi doctrine of Sunni Islam. The group is also known as Daesh (داعش‎ dāʿish, IPA: [ˈdaːʕiʃ]), which is an acronym derived from its Arabic name ad-Dawlah al-Islāmiyah fī 'l-ʿIrāq wa-sh-Shām (الدولة الإسلامية في العراق والشام‎).

The Kingdom of Iraq under British Administration or Mandatory Iraq (Arabic: الانتداب البريطاني على العراق‎ al-Intidāb al-Brīṭānī ‘Alá al-‘Irāq) was created in 1921 following the 1920 Iraqi Revolt against the proposed British Mandate of Mesopotamia, and enacted via the 1922 Anglo-Iraqi Treaty.

Faisal ibn Husayn, who had been proclaimed King of Syria by a Syrian National Congress in Damascus in March 1920, was ejected by the French in July of the same year. Faisal was then granted by the British the territory of Iraq, to rule it as a kingdom, with the British Royal Air Force (RAF) retaining certain military control, though de facto; the territory remained under British administration until 1932.

The civil government of postwar Iraq was headed originally by the High Commissioner, Sir Percy Cox, and his deputy, Colonel Arnold Wilson. British reprisals after the murder of a British officer in Najaf failed to restore order. The most striking problem facing the British was the growing anger of the nationalists, who continued to fight against the imposition of British authority. British administration had yet to be established in Iraqi Kurdistan.

Mesopotamia (/ˌmɛsəpəˈteɪmiə/, from the Ancient Greek: Μεσοποταμία "[land] between rivers"; from Ancient Armenian՝ Միջագետք(Mijagetq), Arabic: بلاد الرافدين‎ bilād ar-rāfidayn; Persian: میان‌رودان‎‎ miyān rodān; Syriac: ܒܝܬ ܢܗܪܝܢ‎ Beth Nahrain "land of rivers") is a name for the area of the Tigris–Euphrates river system, roughly corresponding to modern-day Iraq, Syria and Kuwait, including regions along the Turkish-Syrian and Iran–Iraq borders.

Widely considered to be the one of the cradles of civilization by the Western world, Bronze Age Mesopotamia included Sumer and the Akkadian, Babylonian, and Assyrian empires, all native to the territory of modern-day Iraq. In the Iron Age, it was controlled by the Neo-Assyrian and Neo-Babylonian Empires.

The indigenous Sumerians and Akkadians (including Assyrians and Babylonians) dominated Mesopotamia from the beginning of written history (c. 3100 BC) to the fall of Babylon in 539 BC, when it was conquered by the Achaemenid Empire. It fell to Alexander the Great in 332 BC, and after his death, it became part of the Greek Seleucid Empire.
