Jihadism is a neologism for militant Islamic movements that seek to base the state on Islamic principles. In a narrower sense, it refers to the belief held by some Muslims that armed confrontation with political rivals is an efficient and theologically legitimate method of socio-political change. It is a form of religious violence and has been applied to various insurgent Islamic extremist, militant Islamist, and terrorist individuals and organizations whose ideologies are based on the Islamic notion of lesser jihad from the classical interpretation of Islam. It has also been applied to various Islamic empires in history, such as the Rashidun and Umayyad caliphates of the early Muslim conquests, and the Ottoman Empire. There were also the Fula jihads in West Africa in the 18th and 19th centuries.

Salafi jihadism, also known as Salafi-jihadism, jihadist Salafism and revolutionary Salafism, is a religiopolitical Sunni Islamist ideology that seeks to establish a global caliphate. In a narrower sense, jihadism refers to the belief that armed confrontation with political rivals is an efficient and theologically legitimate method of socio-political change. 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".

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.

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 ideology of the Islamic State, unoffically referred to as Islamic Statism, has been described as being a blend 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".

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.
Yahya al-Bahrumi was an American jihadist, Islamic scholar, and supporter of the Islamic State (ISIL). Having converted to Islam, he studied to the point of developing "a staggering mastery of Islamic law and classical Arabic language and literature". He was close to Abu Muhammad al-Adnani, the ISIL spokesman, chief strategist, and director of foreign terror operations.
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. Although the other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces which 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, the modern iteration of the Islamic State was formed after the U.S. occupational forces outlawed the Iraqi branch of the Arab Socialist Ba'ath Party putting the Sunni soldiers and bureaucrats out of work.
Hazimism, also referred to as the Hazimi movement or known as the Hazimiyyah or Hazimi current, was an extremist movement 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. It has been described as "ultra-extreme" and "even more extreme than ISIS". The movement was eventually branded as extremist by ISIS, who initiated a crackdown on its followers.
