Jihad in the context of "Revolutionary Islamism"

The Arab Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Arab Muslim rule until conquered in turn by the Normans in the 11th century.

Although Sicily had been raided by the Muslim Arabs since the mid-7th century, these raids did not threaten Byzantine control over the island, which remained a largely peaceful backwater. The opportunity for the Aghlabid emirs of Ifriqiya (present-day Tunisia) came in 827, when the commander of the island's fleet, Euphemius, rose in revolt against the Byzantine Emperor Michael II. Defeated by loyalist forces and driven from the island, Euphemius sought the aid of the Aghlabids, an Arab dynasty. The latter regarded this as an opportunity for expansion and for diverting the energies of their own fractious military establishment and alleviating the criticism of the Islamic scholars by championing jihad, and dispatched an army to aid him. Following the Arab landing on the island, Euphemius was quickly sidelined. An initial assault on the island's capital, Syracuse, failed, but the Muslims were able to weather the subsequent Byzantine counter-attack and hold on to a few fortresses. With the aid of reinforcements from Ifriqiya and Umayyad al-Andalus, in 831 they took Palermo, which became the capital of the new Arab-Muslim province.

The Third Anglo-Afghan War was a short war which began on 3 May and ended on 8 August 1919. The new Amir of the Emirate of Afghanistan Amanullah Khan declared a Jihad against the British in the hope to proclaim full independence, as well as to strengthen his own legitimacy. Amanullah's forces invaded British India on three fronts taking advantage of the unrest in India, in an effort to seize the old Afghan provinces west of the River Indus.

Initial victories saw the Afghans invade across the border, defeating the British and occupying Bagh. The British retaliated, leading a counterattack that routed the Afghans. Conflict continued in Kurram, which saw the British overwhelmed. Taking their own initiative, the British seized Spin Boldak in the south, while an Afghan offensive in Thal was contained, with the British occupying Dacca in turn by the end of May. The Royal Air Force were also used in bombing and strafing attacks on the frontier tribes as well as targets within Afghanistan, including Kabul and Jalalabad. Although small in scale, it was a contributing force for Amanullah to call for an armistice in June.

Jihadism is a neologism for modern, armed militant Islamic movements that seek to establish states based on Islamic principles. In a narrower sense, it refers to the belief that armed confrontation is an efficient and theologically legitimate method of socio-political change towards an Islamic system of governance. The term "jihadism" has been applied to various Islamic extremist or Islamist individuals and organizations with militant ideologies based on the classical Islamic notion of lesser jihad.

Jihadism has its roots in the late 19th- and early 20th-century ideological developments of Islamic revivalism, which further developed into Qutbism and Salafi jihadism related ideologies during the 20th and 21st centuries. Jihadist ideologues envision jihad as a "revolutionary struggle" against the international order to unite the Muslim world under Islamic law.

The Regency of Algiers was an early modern semi-independent Ottoman province and nominal vassal state on the Barbary Coast of North Africa from 1516 to 1830. Founded by the privateer brothers Aruj and Hayreddin Reis (also known as the Barbarossa brothers), the Regency succeeded the Kingdom of Tlemcen as a formidable base that waged maritime holy war (Jihad) on European Christian powers. It was ruled by elected regents under a stratocracy led by Janissaries and corsairs. Despite its pirate reputation in Europe, Algiers maintained long-standing diplomatic ties with European states and was a recognized Mediterranean power.

The Regency emerged in the 16th-century Ottoman–Habsburg wars. As self-proclaimed ghazis gaining popular support and legitimacy from the religious leaders at the expense of hostile local emirs, the Barbarossa brothers and their successors carved a unique corsair state that drew revenue and political power from its naval warfare against Habsburg Spain. In the 17th century, when the wars between Spain and the Ottoman Empire, Kingdom of France, Kingdom of England and Dutch Republic ended, Barbary corsairs started capturing merchant ships and their crews and goods from these states. When the Ottomans could not prevent these attacks, European powers negotiated directly with Algiers and also took military action against it. This policy would emancipate Algiers from the Ottomans.

The Algerian Civil War (Arabic: الحرب الأهلية الجزائرية), known in Algeria as the Black Decade (Arabic: العشرية السوداء, French: La décennie noire), was a civil war fought between the Algerian government and various Islamist rebel groups from 11 January 1992 (following a coup negating an Islamist electoral victory) to 8 February 2002. The war began slowly, as it initially appeared the government had successfully crushed the Islamist movement, but armed groups emerged to declare jihad and by 1994, violence had reached such a level that it appeared the government might not be able to withstand it. By 1996–97, it had become clear that the Islamist resistance had lost its popular support, although fighting continued for several years after.

The war has been referred to as 'the dirty war' (la sale guerre), and saw extreme violence and brutality used against civilians. Islamists targeted journalists, over 70 of whom were killed, and foreigners, over 100 of whom were killed, although it is thought by many that security forces as well as Islamists were involved, as the government had infiltrated the insurgents. Children were widely used, particularly by the rebel groups. Total fatalities have been estimated at 44,000 to between 100,000 and 200,000.

The Mahdist State, also known as Mahdist Sudan or the Sudanese Mahdiyya, was a state based on a religious and political movement launched in 1881 by Muhammad Ahmad (later Muhammad al-Mahdi) against the Khedivate of Egypt, which had ruled Sudan since 1821. After four years of struggle, the Mahdist rebels overthrew the Ottoman-Egyptian administration and established their own "Islamic and national" government with its capital in Omdurman. Thus, from 1885 the Mahdist government maintained sovereignty and control over the Sudanese territories until its existence was terminated by Anglo-Egyptian forces in 1898.

Muhammad Ahmad al-Mahdi enlisted the people of Sudan in what he declared a jihad against the administration that was based in Khartoum, which was dominated by Egyptians and Turks. The Khartoum government initially dismissed the Mahdi's revolution. He defeated two expeditions sent to capture him in the course of a year. The Mahdi's power increased, and his call spread throughout Sudan, with his movement becoming known as the Ansar. During the same period, the 'Urabi revolution broke out in Egypt, with the British occupying the country in 1882. Britain appointed Charles Gordon as General-Governor of Sudan. Months after his arrival in Khartoum and after several battles with the Mahdi rebels, Mahdist forces captured Khartoum, and Gordon was killed in his palace. The Mahdi did not live long after this victory, and his successor Abdallahi ibn Muhammad consolidated the new state, with administrative and judiciary systems based on their interpretation of Islamic law. The Coptic Christians, who composed a substantial portion of the country's population, were forced to convert to Islam.

Thomas Scott Asbridge (born 1969) is a historian at Queen Mary University of London, a position he has held since 1999. He is the author of The First Crusade: A New History (2004), a book which describes the background, events, and consequences of the First Crusade, as well as of The Crusades: The War for the Holy Land (2010), a volume providing a view on the crusading movement, portraying the ideas of justified violence and jihad.

Asbridge graduated from Cardiff University with a BA in Ancient and Medieval History, before earning his PhD at the Royal Holloway, University of London. Asbridge's first major work was a revised version of his doctoral thesis, titled The Creation of the Principality of Antioch, 1098–1130. Asbridge also wrote and presented a three-part BBC Two series on The Crusades, and was the historical consultant for Kingdom of Heaven (2005).

The 1465 Moroccan revolution was a popular uprising in the city of Fez, which was the capital of Morocco, against Sultan Abd al-Haqq II, the last ruler of the Marinid dynasty, and his Jewish vizier, Harun ibn Batash.

Morocco was in severe crisis in the mid-15th century, including a progressive Portuguese invasion of the country. The theoretical rulers, the Marinids, had little power outside the city of Fez, with large parts of the country in the hands of the Wattasids, a dynasty of viziers. In 1458, Abd al-Haqq regained power from the Wattasids. The sultan then appointed Jews to high-ranking positions in the state, despite opposition from the mostly Muslim citizens of Fez. In most accounts, the actual revolution began in 1465, when a Jewish official abused a female sharif and a preacher, who heard this began calling for a jihad against the Jews, which led to a pogrom against the Jewish community possibly led by Muhammad ibn Imran, the leader of the sharifs of Fez. Abd al-Haqq was either lynched or executed, and Muhammad ibn Imran became ruler of Fez.
