Jihadism is a neologism for militant Islamic movements that are perceived as existentially threatening to the West. It has been applied to various insurgent Islamic extremist, militant Islamist, and terrorist individuals and organizations whose ideologies are based on the Islamic notion of jihad. It has also been applied to various Islamic empires in history, such as the Umayyad Caliphate and the Ottoman Empire, who extensively campaigned against non-Muslim nations in the name of jihad.
The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS) and by its Arabic acronym Daesh, is a transnational Salafi jihadist group and a former unrecognised quasi-state. Its origins were in the Jai'sh al-Taifa al-Mansurah organization founded by Abu Omar al-Baghdadi in 2004, which fought alongside al-Qaeda during the Iraqi insurgency. The group gained global prominence in 2014, when its militants successfully captured large territories in northwestern Iraq and eastern Syria, taking advantage of the ongoing Syrian civil war. By the end of 2015, it ruled an area with an estimated population of twelve million people, where it enforced its extremist interpretation of Islamic law, managed an annual budget exceeding US$1 billion, and commanded more than 30,000 fighters.
Salafi jihadism, also known as revolutionary Salafism or jihadist Salafism, is a religious-political Sunni Islamist ideology that seeks to establish a global caliphate, characterized by the advocacy of "physical" (military) jihadist attacks on non-Muslim targets. The Salafist interpretation of sacred Islamic texts is "in their most literal, traditional sense", which adherents claim will bring about the return to "true Islam".
Al-Nusra Front, also known as Front for the Conquest of the Levant, was a Salafi jihadist organization fighting against Syrian Ba'athist government forces in the Syrian Civil War. Its aim was to overthrow president Bashar al-Assad and establish an Islamic state in Syria.
Harakat Ahrar al-Sham al-Islamiyya, commonly referred to as Ahrar al-Sham, is a coalition of multiple Islamist units that coalesced into a single brigade and later a division in order to fight against the Syrian Government led by Bashar al-Assad during the Syrian Civil War. Ahrar al-Sham was led by Hassan Aboud until his death in 2014. In July 2013, Ahrar al-Sham had 10,000 to 20,000 fighters, which at the time made it the second most powerful unit fighting against al-Assad, after the Free Syrian Army. It was the principal organization operating under the umbrella of the Syrian Islamic Front and was a major component of the Islamic Front. With an estimated 20,000 fighters in 2015, Ahrar al-Sham became the largest rebel group in Syria after the Free Syrian Army became less powerful. Ahrar al-Sham and Jaysh al-Islam are the main rebel groups supported by Turkey. On 18 February 2018, Ahrar al-Sham merged with the Nour al-Din al-Zenki Movement to form the Syrian Liberation Front.
Foreign fighters have fought on all four sides of the Syrian Civil War, as well both sides of the War in Iraq. In addition to Sunni foreign fighters, Shia fighters from several countries have joined pro-government militias in Syria, leftist militants have joined Kurdish forces, and other foreign fighters have joined jihadist organizations and private military contractors recruit globally. Estimates of the total number of foreign Sunnis who have fought for the Syrian rebels over the course of the conflict range from 5,000 to over 10,000, while foreign Shia fighters numbered around 10,000 or less in 2013 rising to between 15,000 and 25,000 in 2017.
Mohammed Emwazi was a British militant of Kuwaiti origin seen in several videos produced by the Islamist extremist group Islamic State (IS) showing the beheadings of a number of captives in 2014 and 2015.

The Islamic State of Iraq and the Levant (ISIL) is proscribed as a terrorist organisation by the United Kingdom. British citizens have fought as members of the group, and there has been political debate on how to punish them. On 26 September 2014, Parliament voted to begin Royal Air Force airstrikes against ISIL in northern Iraq at the request of the Iraqi government, which began four days later, using Tornado GR4 jets. On 2 December 2015, the UK Parliament authorised an extension to the Royal Air Force airstrike campaign, joining the US-led international coalition against ISIL in Syria. Hours after the vote, Royal Air Force Tornado jets began bombing ISIL-controlled oilfields.
"The Beatles" was the nickname for an Islamic State terrorist group composed of four British militants. The group was named by their hostages after the English rock group The Beatles, who referred to the members as "John", "Paul", "George", and "Ringo".
The ideology of the Islamic State, sometimes called Islamic Statism, has been described as being a hybrid of Salafism, Salafi jihadism, Sunni Islamist fundamentalism, Wahhabism, and Qutbism. Through its official statement of beliefs originally released by its first leader Abu Omar al-Baghdadi in 2007 and subsequently updated since June 2014, the Islamic State defined its creed as "a middle way between the extremist Kharijites and the lax Murji'ites".

According to the Institute for Strategic Dialogue, they were among an estimated 550 women and girls from Western countries who had travelled to join IS—part of what some have called "a jihadi, girl-power subculture", the so-called Brides of ISIL. As of 2024, one girl has been reported killed (Sultana), one girl has been stripped of her British nationality and denied re-entry into the country (Begum) while the third's fate is unknown (Abase).
The Sheikh Omar Hadid Brigade, also known as Islamic State in Gaza, is an Islamist militant group affiliated with the Islamic State in Iraq and the Levant that was reportedly active in the Gaza Strip around 2015. Its goals have consistently matched those of the Islamic State, in that it seeks to establish the al-Sham caliphate. As such, it opposes all forms of Palestinian nationalism while also supporting the elimination of all Jews and other ethno-religious 'infidels' from the region.
The origins of the Islamic State group can be traced back to three main organizations. Earliest of these was the "Jamāʻat al-Tawḥīd wa-al-Jihād" organization, founded by the Jihadist leader Abu Mus'ab al-Zarqawi in Jordan in 1999. The other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces. These included the "Jaish al-Ta'ifa al-Mansurah" group founded by Abu Omar al-Baghdadi in 2004 and the "Jaysh Ahl al-Sunnah wa’l-Jama’ah" group founded by Abu Bakr al-Baghdadi and his associates in the same year.
Hazimism, also referred to as the Hazimi movement or known as the hazimiyyah or Hazimi current, was an extremist current within the Ideology of Islamic State. The movement was based on the doctrines of the Saudi-born Muslim scholar Ahmad ibn Umar al-Hazimi, which was adopted by many Tunisian recruits in IS. Hazimis believe that those who do not unconditionally excommunicate (takfir) unbelievers are themselves unbelievers, which opponents argue leads to an unending chain of takfir." Its spread within ISIS triggered prolonged ideological conflict within the group, pitting its followers against the moderate faction led by Turki al-Binali. The movement was eventually branded as extremist by ISIS, who initiated a crackdown on its followers.
Jamaah Ansharusy Syariah is an Islamist organization split from Jamaah Ansharut Tauhid.

JAS objective is the rival of JAT recruitment for followers in support of the full implementation of Sharia in Indonesia. JAS claimed a membership of 2,000 in Jakarta, West Java, Central Java, East Java, West Nusa Tenggara, and Bengkulu.
