The religio-political ideology of Islamism (also often called political Islam or Islamic fundamentalism) , according to author Robin Wright, it has significantly redefined politics and borders in the Middle East since modern states gained independence, redefining "politics and even borders" (according to at least one observer (author Robin Wright). It is active in many countries around the world.

Islamism has many different varieties, but has been described an ideology seeking to revive Islam to its past assertiveness and glory,Burgat, François, "The Islamic Movement in North Africa", U of Texas Press, 1997, pp. 39–41, 67–71, 309 purify it of foreign elements, reassert its role into “social and political as well as personal life"; and in particular reorder "government and society in accordance with laws prescribed by Islam" (aka Sharia).Shepard, W. E. Sayyid Qutb and Islamic Activism: A Translation and Critical Analysis of Social Justice in Islam. Leiden, New York: E.J. Brill. (1996). p. 40

Central and prominent figures in 20th-century Islamism include Hassan al-Banna (founder of the Muslim Brotherhood), Sayyid Qutb, Abul A'la Maududi,Fuller, Graham E., The Future of Political Islam, Palgrave MacMillan, (2003), p. 120 Ruhollah Khomeini (founder of the Islamic Republic of Iran), Hassan Al-Turabi.

Al-Banna and Maududi called for a "reformist" strategy to re-Islamizing society through grassroots social and political activism.Roy, Failure of Political Islam, 1994: p. 24 Other Islamists (Al-Turabi) have advocated a "revolutionary" strategy of Islamizing society through exercise of state power, or for combining grassroots Islamization with violent revolution (Sayyid Qutb). The term has been applied to non-state reform movements, political parties, militias and revolutionary groups. Islamists emphasize the implementation of sharia, pan-Islamic political unity, the creation of Islamic states,Soage, Ana Belén. "Introduction to Political Islam." Religion Compass 3.5 (2009): 887–96. (eventually unified), and rejection of non-Muslim influences—particularly Western or universal economic, military, political, social, or cultural.

At least one author (Graham E. Fuller) has argued for a broader notion of Islamism as a form of identity politics, involving "support for [Muslim] identity, authenticity, broader regionalism, revivalism, [and] revitalization of the community."Fuller, Graham E., The Future of Political Islam, Palgrave MacMillan, (2003), p. 21 Islamists themselves prefer terms such as "Islamic movement", or "Islamic activism" to "Islamism", objecting to the insinuation that Islamism is anything other than Islam renewed and revived. In public and academic contexts, the term "Islamism" has been criticized as having been given connotations of violence, extremism, and violations of human rights, by the Western mass media, leading to Islamophobia and stereotyping.

Following the Arab Spring, many post-Islamist currents became heavily involved in democratic politics, while others spawned "the most aggressive and ambitious Islamist militia" to date, such as the Islamic State of Iraq and the Levant (ISIL).

Afghanistan (Taliban)

In Afghanistan, the mujahideen's victory against the Soviet Union in the 1980s did not lead to justice and prosperity, due to a vicious and destructive civil war between political and tribal warlords, making Afghanistan one of the poorest countries on earth. In 1992, the Democratic Republic of Afghanistan ruled by communist forces collapsed, and democratic Islamist elements of mujahideen founded the Islamic State of Afghanistan. In 1996, a more conservative and anti-democratic Islamist movement known as the Taliban rose to power, defeated most of the warlords and took over roughly 80% of Afghanistan.

The Taliban were spawned by the thousands of madrasahs the Deobandi movement established for impoverished Afghan refugees and supported by governmental and religious groups in neighboring Pakistan.Rashid, Taliban (2000), pp. 26, 32 The Taliban differed from other Islamist movements to the point where they might be more properly described as Islamic fundamentalist or neofundamentalist, interested in spreading "an idealized and systematized version of conservative tribal village customs" under the label of Sharia to an entire country. Their ideology was also described as being influenced by Wahhabism, and the extremist jihadism of their guest Osama bin Laden.Rashid, Taliban, (2000), pp. 132, 139Encyclopedia of Islam and the Muslim World, (2004)

The Taliban considered "politics" to be against Sharia and thus did not hold elections. They were led by Abdul Ghani Baradar and Mohammed Omar who was given the title "Amir al-Mu'minin" or Commander of the Faithful, and a pledge of loyalty by several hundred Taliban-selected Pashtun clergy in April 1996. Taliban were overwhelmingly Pashtun and were accused of not sharing power with the approximately 60% of Afghans who belonged to other ethnic groups. (see: Taliban#Ideology and aims)Rashid, Taliban (2000), pp. 98, 101

The Taliban's hosting of Osama bin Laden led to an American-organized attack which drove them from power following the 9/11 attacks. The Taliban continued to fight a vigorous insurgency with suicide bombings and armed attacks being launched against NATO and Afghan government targets. The Taliban re-established control of the country in 2021 following a 2020 peace agreement with the United States and the overthrow of the US-backed government.

Algeria

In 1989, a broad Islamist coalition movement was founded in Algeria known as the FIS or Front Islamique de Salut (the Islamic Salvation Front). Led by Abbassi Madani, and a charismatic Islamist young preacher, Ali Belhadj, it was influenced by Salafism and the jihad in Afghanistan, as well as the Muslim Brotherhood. Taking advantage of economic failure and unpopular social liberalization and secularization of the ruling leftist-nationalist FLN government, it used its preaching to advocate the establishment of a legal system following Sharia law, economic liberalization and development program, education in Arabic rather than French, and gender segregation, with women staying home to alleviate the high rate of unemployment among young Algerian men. The FIS won sweeping victories in local elections and was set to win national elections in 1991, when voting was canceled by a military coup d'état.

As Islamists took up arms to overthrow the government, the FIS's leaders were arrested and it became overshadowed by Islamist guerrilla groups, particularly the Islamic Salvation Army, MIA and Armed Islamic Group (or GIA). A bloody and devastating civil war ensued in which between 150,000 and 200,000 people were killed over the next decade.

The civil war was not a victory for Islamists. By 2002 the main guerrilla groups had either been destroyed or had surrendered. The popularity of Islamist parties has declined to the point that "the Islamist candidate, Abdallah Jaballah, came a distant third with 5% of the vote" in the 2004 presidential election."International: Freer and more peaceful; An election in Algeria," The Economist, April 17, 2004. V.371, n. 8371; p. 56

Bangladesh Jamaat-e-Islami Bangladesh is the largest Islamist party in the country and supports the implementation of Sharia law and promotes the country's main right-wing politics. Since 2000, the main political opposition Bangladesh Nationalist Party (BNP) has been allied with it and another Islamic party, Islami Oikya Jote. Some of their leaders and supporters, including former ministers and MPs, have been hanged for alleged war crimes during Bangladesh's struggle for independence and speaking against the ruling Bangladesh Awami League.

Belgium In the 2012, the party named ISLAM had four candidates and they were elected in Molenbeek and Anderlecht. In 2018, they ran candidates in 28 municipalities. Its policies include schools must offer halal food and women must be able to wear a headscarf anywhere. Another of the Islam Party's goals is to separate men and women on public transportation. The party's president argues this policy will help protect women from sexual harassment.

Denmark

The Islamist movements gradually grew since the 1990s. The first Islamist groups and networks were predominantly influenced by the countries they immigrated from. Those involved had close contact with militant Islamists in the Middle East, South Asia and North Africa. Their operations had supporting militant groups financially as their first priority. Since the 1990s, people from the Islamist movements joined several conflicts to train with or participate in fighting with Islamist militants.

In the 2000s the Islamist movements grew and by 2014 there were militants among the Islamist movements in Copenhagen, Aarhus and Odense. Several people from crime gangs join Islamist movements that sympathise with militant Islamism. The militant Islamist movement were estimated to encompass some hundreds in 2014.

The Danish National Centre for Social Research released a report commissioned by the Ministry of Children, Integration and Social Affairs documenting 15 extremist groups operating in Denmark. Most were non-Muslim far-right or far-left groups, but five were Sunni Islamist groups. These Sunni Islamist groups include Hizb ut-Tahrir Denmark, Dawah-bærere (Dawah Carriers), Kaldet til Islam (The Call to Islam), Dawah-centret (The Dawah Centre), and the Muslimsk Ungdomscenter (The Muslim Youth Centre). All of these Sunni Islamist groups operate in Greater Copenhagen with the exception of Muslimsk Ungdomscenter, which operates in Aarhus. Altogether, roughly 195 to 415 Muslims belong to one of these organizations and most are young men.

Egypt (Jihadism)

While Qutb's ideas became increasingly radical during his imprisonment prior to his execution in 1966, the leadership of the Brotherhood, led by Hasan al-Hudaybi, remained moderate and interested in political negotiation and activism. Fringe or splinter movements inspired by the final writings of Qutb in the mid-1960s (particularly the manifesto Milestones, a.k.a. Ma'alim fi-l-Tariq) did, however, develop and they pursued a more radical direction.Wright, Lawrence, Looming Tower, (2006), p. 332 By the 1970s, the Brotherhood had renounced violence as a means of achieving its goals.

The path of violence and military struggle was then taken up by the Egyptian Islamic Jihad organization responsible for the assassination of Anwar Sadat in 1981. Unlike earlier anti-colonial movements the extremist group directed its attacks against what it believed were "apostate" leaders of Muslim states, leaders who held secular leanings or who had introduced or promoted Western/foreign ideas and practices into Islamic societies. Its views were outlined in a pamphlet written by Muhammad Abd al-Salaam Farag, in which he states: ...there is no doubt that the first battlefield for jihad is the extermination of these infidel leaders and to replace them by a complete Islamic Order...

Another of the Egyptian groups which employed violence in their struggle for Islamic order was al-Gama'a al-Islamiyya (Islamic Group). Victims of their campaign against the Egyptian state in the 1990s included the head of the counter-terrorism police (Major General Raouf Khayrat), a parliamentary speaker (Rifaat al-Mahgoub), dozens of European tourists and Egyptian bystanders, and over 100 Egyptian police. Ultimately the campaign to overthrow the government was unsuccessful, and the major jihadi group, Jamaa Islamiya (or al-Gama'a al-Islamiyya), renounced violence in 2003. Other lesser known groups include the Islamic Liberation Party, Salvation from Hell and Takfir wal-Hijra, and these groups have variously been involved in activities such as attempted assassinations of political figures, arson of video shops and attempted takeovers of government buildings.Mazih Ayubi, Political Islam, 1991, p. 73
