Islamic StateThe Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL; ˈaɪsᵻl), Islamic State of Iraq and Syria (ISIS; ˈaɪsᵻs), and by its Arabic acronym Da'ish or Daesh (داعش, Dāʿish, ˈdaːʕɪʃ), is a transnational militant Islamist terrorist group and former unrecognized quasi-state that follows the Salafi jihadist branch of Sunni Islam. It was founded by Abu Musab al-Zarqawi in 1999 and gained global prominence in 2014, when it captured a large amount of Iraqi territory, and took advantage of the civil war in Syria to take control of chunks of territory in Eastern Syria.
History of IslamThis history of Islam concerns the political, social, economic, military, and cultural developments of the Islamic civilization. Most historians believe that Islam originated in Mecca and Medina at the start of the 7th century CE. Muslims regard Islam as a return to the original faith of the Abrahamic prophets, such as Adam, Noah, Abraham, Moses, David, Solomon, and Jesus, with the submission (Islām) to the will of God.
Twelver Shi'ismTwelver Shīʿism (ٱثْنَا عَشَرِيَّة; DIN), also known as Imāmiyya (إِمَامِيَّة), is the largest branch of Shīʿa Islam, comprising about 85 percent of all Shīʿa Muslims. The term Twelver refers to its adherents' belief in twelve divinely ordained leaders, known as the Twelve Imams, and their belief that the last Imam, Imam al-Mahdi, lives in Occultation and will reappear as the promised Mahdi (المهدي المنتظر). Twelvers believe that the Twelve Imams are the spiritual and political successors to the Islamic prophet Muhammad.
Ottoman CaliphateThe caliphate of the Ottoman Empire (hilâfet makamı) was the claim of the heads of the Turkish Ottoman dynasty to be the caliphs of Islam in the late medieval and the early modern era. During the period of Ottoman expansion, Ottoman rulers claimed caliphal authority after the conquest of Mamluk Egypt by sultan Selim I in 1517, which bestowed the title of Defender of the Holy Cities of Mecca and Medina upon him and strengthened the Ottoman claim to caliphate in the Muslim world.
SaqifaThe Saqifa (سَّقِيفَة) of the Banu Sa'ida clan refers to the location of an event in early Islam where some of the companions of the Islamic prophet Muhammad pledged their allegiance to Abu Bakr as the first caliph and successor to Muhammad shortly after his death in 11 AH (632 CE). The Saqifa meeting is among the most controversial events in early Islam, due to the exclusion of a large number of Muhammad's companions, including his immediate family and notably Ali, his cousin and son-in-law.
IslamismIslamism (also often called political Islam) is a religio-political ideology. There is no consensus definition of Islamism, which has many varieties and alternative names, and some have objected to use of the term, either for its being derogatory, or so broad and flexible as to have lost its meaning. In its original formulation, Islamism described an ideology seeking to revive Islam to its past assertiveness and glory, purifying it of foreign elements, reasserting its role into "social and political as well as personal life"; and in particular "reordering government and society in accordance with laws prescribed by Islam" (aka Sharia).
