ISIS Today: History, Ideology, Global Network and Current Threat in 2026

ISIS Today: History, Ideology, Global Network and Current Threat in 2026

Introduction

The Islamic State (ISIS/ISIL/Daesh) is a transnational terrorist organization that emerged from the conflict in Iraq and later established a major territorial presence across Iraq and Syria.

At its peak, ISIS controlled large areas of territory and proclaimed a so-called “caliphate” in 2014. Its territorial project was eventually dismantled through military campaigns by Iraqi, Syrian, Kurdish and international forces.

However, the destruction of its territorial state did not completely eliminate the organization.

In 2026, ISIS is better understood as a decentralized terrorist network and collection of regional affiliates, rather than the territorial organization that controlled Mosul and Raqqa.

The United Nations continues to describe Daesh and its affiliates as a persistent international security threat. Its 2026 assessments highlight particular concerns in Africa, Syria and Iraq, and Afghanistan.

1. What Is ISIS?

ISIS stands for Islamic State in Iraq and Syria.

Other names include:

- Islamic State (IS)

- Islamic State of Iraq and the Levant (ISIL)

- Daesh/Da'esh

- Islamic State group

The organization promotes an extremist interpretation of Islam and seeks political control through violence and coercion.

Its ideology has been rejected by Muslim scholars, governments and communities around the world.

---

2. Origins of ISIS

ISIS developed from militant networks associated with the Iraq War.

One important predecessor was al-Qaeda in Iraq (AQI), founded by Abu Musab al-Zarqawi.

After Zarqawi's death in 2006, the organization underwent several transformations and became associated with the Islamic State of Iraq.

The Syrian civil war beginning in 2011 created a new environment for the organization.

ISIS expanded across the Iraq-Syria border and eventually became one of the most powerful armed extremist organizations in the region.

---

3. Abu Bakr al-Baghdadi

Abu Bakr al-Baghdadi became the most important leader of ISIS during its expansion.

In 2014, after major territorial gains in Iraq and Syria, ISIS announced the creation of its so-called caliphate.

Baghdadi presented himself as its leader.

This announcement marked the beginning of ISIS's most powerful period.

---

4. The Rise of the ISIS Caliphate

In 2014, ISIS captured major cities and large territories in Iraq and Syria.

Its most important territorial centers included:

- Mosul in Iraq

- Raqqa in Syria

- Large areas of northern and western Iraq

- Large parts of eastern and northern Syria

The organization controlled territory containing millions of people.

This was unusual for a modern terrorist organization.

ISIS attempted to behave like a state, creating administrative structures, courts, taxation systems and security organizations while imposing its extremist ideology through brutal coercion.

---

5. The Capture of Mosul

The fall of Mosul in June 2014 became one of ISIS's most important victories.

Iraqi government forces were overwhelmed and ISIS captured the city.

Baghdadi subsequently appeared at the Great Mosque of al-Nuri, where he declared his so-called caliphate.

Mosul became the symbolic center of ISIS's Iraqi territorial project.

---

6. Raqqa: The Syrian Stronghold

In Syria, Raqqa became the principal political and administrative center of ISIS.

The city became internationally associated with the organization's rule.

ISIS used territory in Syria to support its operations, administration and propaganda.

The eventual loss of Raqqa represented a major strategic setback.

---

7. ISIS Propaganda

Propaganda was central to ISIS's strategy.

The organization attempted to present itself as:

- Powerful

- International

- Ideologically revolutionary

- Capable of governing territory

Its propaganda targeted audiences far beyond Iraq and Syria.

Digital platforms allowed ISIS supporters and sympathizers to encounter its messaging across borders.

International governments consequently developed new approaches to counter extremist propaganda and online recruitment.

---

8. Foreign Fighters

One of the most significant features of ISIS was the movement of foreign recruits into territories controlled by the organization.

People from numerous countries travelled to Iraq and Syria.

This created a long-term international security problem.

After ISIS lost its territory, governments faced difficult questions concerning:

- Returning citizens

- Detention

- Prosecution

- Rehabilitation

- Children and families associated with fighters

- Preventing future radicalization

---

9. ISIS and Violence

ISIS became internationally notorious for terrorism, mass violence, persecution and attacks against civilians.

Its victims included:

- Muslims

- Christians

- Yazidis

- Other religious minorities

- Security personnel

- Journalists

- Aid workers

- Local communities

The Yazidi genocide became one of the most serious examples of ISIS's persecution of a religious minority.

The organization's violence was also directed against Muslims who rejected its ideology.

---

10. The International Campaign Against ISIS

The rapid expansion of ISIS led to the creation of an international coalition.

The Global Coalition Against Daesh was formed in 2014.

Its members supported different aspects of the campaign, including:

- Military operations

- Intelligence cooperation

- Counter-financing

- Stabilization

- Humanitarian assistance

- Countering extremist propaganda

- Foreign-fighter prevention

Iraq and local Syrian forces were central to the campaign.

---

11. The Battle for Mosul

The campaign to retake Mosul became one of the largest battles against ISIS.

Iraqi security forces, supported by an international coalition, gradually pushed ISIS out of the city.

Mosul was eventually liberated in July 2017.

The defeat represented a major turning point.

ISIS lost one of its most important cities and much of its ability to function as a territorial government.

---

12. The Fall of Raqqa

In 2017, the Syrian Democratic Forces (SDF), supported by the U.S.-led coalition, captured Raqqa from ISIS.

The loss of Raqqa further weakened the organization's territorial structure.

By this point, ISIS was losing city after city.

---

13. The End of the Territorial Caliphate

The final major territorial stronghold of ISIS in Syria was Baghouz.

In March 2019, the SDF announced the defeat of ISIS's territorial control there.

This marked the effective destruction of the organization's territorial “caliphate.”

But it did not mean that ISIS had disappeared.

Its remaining members moved toward underground networks and dispersed communities.

---

14. From Army-Like Force to Underground Network

The transformation after 2019 is one of the most important aspects of ISIS's history.

Before:

ISIS controlled:

Cities + territory + administrative structures + large armed formations

After:

ISIS increasingly relied on:

Cells + clandestine networks + local affiliates + propaganda + decentralized activity

The organization therefore became harder to eliminate completely.

---

15. Death of Abu Bakr al-Baghdadi

Abu Bakr al-Baghdadi was killed during a U.S. operation in Syria in October 2019.

His death was another major leadership loss for ISIS.

However, the organization continued operating.

This demonstrated an important characteristic of terrorist organizations:

Leadership removal does not necessarily destroy an entire network.

---

16. ISIS Today: 2026

The ISIS of 2026 is fundamentally different from the ISIS of 2014.

It no longer controls the enormous territory that it once held in Iraq and Syria.

However, the United Nations continues to describe the organization and its affiliates as a persistent threat.

The UN's July 2026 assessment highlighted ISIS activity particularly in:

- West Africa and the Sahel

- Lake Chad region

- Syria and Iraq

- Afghanistan

The organization has also adapted to newer technologies and communication environments.

---

17. ISIS in Iraq

ISIS remains present in Iraq, but its capabilities are dramatically smaller than during the 2014–2017 period.

It operates primarily through underground networks rather than territorial government.

The UN's 2026 assessment described ISIS as being at a comparatively weak level in Iraq, with its remaining strength estimated in the low hundreds.

Iraq therefore faces a different problem today:

preventing a weakened insurgent network from rebuilding.

---

18. ISIS in Syria

Syria remains important to ISIS.

The organization has exploited instability and political transitions.

A July 2026 UN assessment estimated that ISIS retained around 3,000 fighters in Syria and had shifted toward smaller, hit-and-run activity rather than territorial control.

This represents a major transformation from its former strategy.

Instead of governing large cities, ISIS seeks to survive through dispersed networks.

---

19. ISIS and Detention Camps

Another major issue is the large population of people associated with ISIS who have been held in northeastern Syria.

These include:

- Former fighters

- Family members

- Women

- Children

- Foreign nationals

The situation creates difficult humanitarian, legal and security questions.

Governments have been encouraged to resolve the status of their citizens rather than allowing the detention problem to continue indefinitely.

---

20. ISIS-Khorasan

One of the most internationally significant ISIS affiliates is Islamic State Khorasan Province (ISIS-K/ISIL-K).

It emerged in the Afghanistan-Pakistan region and has become an important security concern.

The UN continues to assess ISIS-K as a serious threat, particularly because of its interest in conducting attacks beyond its immediate operating environment.

---

21. ISIS in Africa

Africa has become increasingly important to the ISIS network.

The organization has affiliates or associated groups in several regions.

Important areas include:

Sahel

ISIS-linked groups operate in parts of:

- Mali

- Burkina Faso

- Niger

Lake Chad

Islamic State West Africa Province (ISWAP) is particularly associated with northeastern Nigeria and the Lake Chad Basin.

Somalia

An ISIS affiliate operates in northern Somalia.

Central and Southern Africa

ISIS-linked activity has also been reported in areas including the Democratic Republic of the Congo and northern Mozambique.

The United Nations has repeatedly highlighted the growing importance of Africa to the overall ISIS threat.

---

22. Why Africa Matters to ISIS

Several factors can create opportunities for terrorist organizations:

- Weak governance

- Local conflicts

- Poverty

- Border insecurity

- Political instability

- Limited state presence

- Communal tensions

- Criminal networks

ISIS affiliates attempt to exploit these conditions.

The UN has emphasized that counterterrorism responses therefore need more than military action; they also require governance, development, justice and regional cooperation.

---

23. ISIS and Technology

ISIS has adapted to technological changes.

The UN reported in 2026 that Daesh and its affiliates have increasingly used or experimented with emerging technologies, including:

- Artificial intelligence

- Digital platforms

- Unmanned aircraft systems

- Virtual assets

The important point is that technology can allow terrorist organizations to communicate and spread propaganda even when they no longer control territory.

---

24. ISIS Financing

ISIS's financial model has also changed.

During its territorial period, the organization could extract revenue from areas it controlled.

After losing territory, that model became much more difficult.

Current assessments point toward more locally generated revenue and, among some affiliates, activities such as kidnapping for ransom and exploitation of informal financial systems.

International governments therefore monitor terrorist financing alongside military and intelligence threats.

---

25. ISIS vs Al-Qaeda

ISIS and al-Qaeda share an extremist ideological background, but they are separate organizations.

A simplified comparison:

Feature| ISIS| Al-Qaeda

Origin| Iraq-based jihadist network| Founded by Osama bin Laden

Major expansion| 2014| Earlier international expansion

Territorial project| Very strong emphasis| Historically less centralized

“Caliphate”| Declared in 2014| Different strategic approach

Current structure| Decentralized affiliates| Decentralized affiliates

Major areas today| Africa, Syria/Iraq, Afghanistan| Multiple regions

Relationship| Rival organization| Rival of ISIS

ISIS emerged partly from the Iraqi jihadist environment associated with al-Qaeda, but the two organizations later became bitter rivals.

---

26. Why ISIS Survived After Losing Its Territory

Several factors help explain its survival.

1. Decentralization

The organization became less dependent on one central headquarters.

2. Local affiliates

Regional branches can operate according to local conditions.

3. Political instability

Civil wars and weak governance create opportunities.

4. Propaganda

Digital communication allows the ideology to survive beyond territorial control.

5. Prison and detention issues

Large populations associated with ISIS remain a long-term security and humanitarian challenge.

6. International conflicts

Global instability can create new environments for extremist organizations.

---

27. ISIS's Greatest Strategic Change

The most important change can be summarized simply:

2014 ISIS = territorial organization

2026 ISIS = decentralized transnational network

This does not mean that ISIS is as powerful today as it was at its territorial peak.

It means the nature of the threat has changed.

---

28. U.S. Counter-ISIS Strategy

The United States and international partners have used several approaches against ISIS:

- Intelligence cooperation

- Local security forces

- Counterterrorism operations

- Financial sanctions

- Counter-propaganda efforts

- Border security

- Prison and detention management

- International law enforcement

- Stabilization assistance

The U.S. military mission against ISIS in Iraq has also entered a new phase.

In September 2026, the United States formally completed its military withdrawal from Iraq, ending the Iraq phase of Operation Inherent Resolve while maintaining counter-ISIS support arrangements and regional capabilities.

This means Iraq now carries greater responsibility for preventing ISIS from rebuilding inside the country.

---

29. The Future Threat

The future of ISIS will depend heavily on conditions outside the organization itself.

Important factors include:

- Political stability

- Civil wars

- Government effectiveness

- Border security

- Prison management

- Economic conditions

- Counterterrorism cooperation

- Online radicalization

- Regional conflicts

The UN's 2026 assessment emphasizes that ISIS continues to adapt despite sustained counterterrorism pressure.

---

30. Is ISIS Defeated?

The answer depends on what “defeated” means.

Territorial ISIS

The territorial caliphate has been destroyed.

Organizational ISIS

The organization still exists.

Global network

ISIS-affiliated groups remain active in several regions.

Ideology

The ideology has not disappeared.

Therefore:

ISIS lost its territorial state, but it did not disappear as a terrorist network.

---

31. Why ISIS Remains a Global Security Issue

ISIS is no longer primarily a conventional military force.

Its importance today comes from its ability to survive through:

decentralization + regional affiliates + propaganda + exploitation of instability.

That makes the problem much more complicated than simply capturing territory.

---

Conclusion

ISIS represents one of the most significant transformations in modern terrorism.

From its origins in the Iraqi insurgency, it developed into a powerful organization that captured major cities, controlled territory across Iraq and Syria, and declared a so-called caliphate in 2014.

Between 2016 and 2019, Iraqi, Syrian, Kurdish and international forces dismantled its territorial control.

But the organization's defeat as a territorial power did not eliminate it.

In 2026, ISIS is primarily a decentralized terrorist network. Its strongest areas of concern have increasingly shifted toward Africa, while Syria, Iraq and Afghanistan remain important parts of the threat landscape.

The central lesson of the ISIS experience is therefore clear:

«Destroying territory can weaken a terrorist organization, but preventing its regeneration requires long-term intelligence, security, governance, international cooperation and prevention efforts.»

ISIS today is smaller and fundamentally different from the organization that captured Mosul in 2014—but its continued adaptation means that international counterterrorism efforts remain necessary.
