From 2006–2026, the main conflicts involving Orthodox Christian peoples/areas/countries and Muslims fall into several categories: some are explicitly jihadist or sectarian; others are ethnic-national conflicts where Orthodox Christianity and Islam mark communal identity but are not necessarily the root cause.
1. Armenia / Artsakh Armenians vs. Azerbaijan and Turkey-backed forces
Who: Armenians, mostly Armenian Apostolic Christians — an Oriental Orthodox church, not Eastern Orthodox — vs. Muslim-majority Azerbaijan, with Turkish support.
Where: Nagorno-Karabakh / Artsakh and surrounding regions.
Relevant period: Especially 2020 and 2023, though the conflict is older.
What happened:
The 2020 Second Nagorno-Karabakh War saw Azerbaijan retake large parts of territory held by Armenian forces since the early 1990s. In 2023, Azerbaijan’s offensive led to the collapse of the Armenian-run Artsakh authorities and the mass flight of nearly the entire Armenian population from Nagorno-Karabakh. The conflict is primarily territorial and national, but it has a strong Christian-Muslim civilizational overlay because Armenians identify heavily with ancient Christian heritage and Azerbaijan is a Turkic, Muslim-majority state. Armenian officials and religious leaders have accused Azerbaijani forces of desecrating churches and Armenian Christian sites, including after the capture of Shusha/Shushi in 2020.
Best classification: Ethno-territorial war with religious-symbolic dimensions.
2. Russia / Orthodox Russia vs. Islamist insurgents in Chechnya, Dagestan, and the North Caucasus
Who: Russian state, culturally tied to Russian Orthodoxy, vs. Muslim separatist and Islamist militants in Chechnya, Dagestan, Ingushetia, and the broader North Caucasus.
Where: North Caucasus, Russian Federation.
Relevant period: The second Chechen war began before 2006, but insurgency and terrorism continued well into the last 20 years.
What happened:
After the Chechen wars, the conflict evolved from a Chechen nationalist/separatist war into a wider Islamist insurgency. Groups like the Caucasus Emirate and later ISIS-linked militants carried out attacks against Russian security forces, civilians, officials, and local Muslim rivals. Dagestan became a major center of insurgent and counterinsurgent violence, with Human Rights Watch documenting abuses by Russian security forces and crimes by insurgents.
Religious dimension:
This is one of the clearest cases of an Orthodox-majority state fighting Muslim Islamist insurgents. But it should not be reduced to “Orthodox vs. Muslim” because many victims and participants were Muslims themselves, including pro-Moscow Chechen forces.
Best classification: State counterinsurgency against Islamist and separatist militancy.
3. Serbia / Kosovo Serbs vs. Muslim-majority Kosovo Albanians
Who: Serbian Orthodox Serbs vs. mostly Muslim ethnic Albanians in Kosovo.
Where: Kosovo, especially northern Kosovo and Serbian Orthodox heritage sites.
Relevant period: 2008–present, after Kosovo declared independence; periodic clashes, not full-scale war.
What happened:
Kosovo declared independence in 2008. Serbia refuses to recognize it. Kosovo is overwhelmingly Albanian and majority Muslim, while the Serb minority is strongly tied to the Serbian Orthodox Church. The last 20 years have included riots, barricades, police confrontations, disputes over local authority in Serb-majority northern Kosovo, and recurring tensions around Serbian Orthodox monasteries and churches. Kosovo’s recent census showed a population that is overwhelmingly Muslim, with a small Orthodox minority, though many Serbs boycotted the census.
Religious dimension:
The conflict is mainly ethnic-national and sovereignty-based: Serbia vs. Kosovo, Serbs vs. Albanians. But Orthodoxy is central to Serbian identity in Kosovo because Kosovo contains major Serbian Orthodox monasteries and is treated in Serbian national memory as sacred historical territory.
Best classification: Ethno-national sovereignty conflict with strong Orthodox-Muslim identity markers.
4. Syria’s Orthodox Christians vs. ISIS, al-Nusra, and other Islamist militants
Who: Greek Orthodox, Syriac Orthodox, Armenian Orthodox/Apostolic, and other Eastern Christian communities vs. Sunni jihadist groups such as ISIS and al-Nusra/Jabhat al-Nusra.
Where: Syria: Aleppo, Homs, Maaloula, Qaryatain, Raqqa, Hasakeh, Damascus, and other areas.
Relevant period: Especially 2011–2026.
What happened:
During the Syrian Civil War, Christian communities, including Orthodox communities, were targeted by jihadist factions. Maaloula, a historically Christian town, was attacked; Greek Orthodox nuns were kidnapped by al-Nusra-linked rebels and later released. ISIS kidnapped Christians in Qaryatain and Hasakeh province. Churches and Christian historical sites were damaged or destroyed in Aleppo, Homs, and elsewhere. In June 2025, an Islamic State suicide attack targeted the Greek Orthodox Saint Elias Church in Damascus, killing 22 and injuring dozens.
Religious dimension:
This is one of the most explicitly religious cases: jihadist groups treated Christians as religious enemies, imposed or threatened jizya, kidnapped clergy and laity, and attacked churches.
Best classification: Civil war plus jihadist persecution of Orthodox and other Christian minorities.
5. Egypt’s Coptic Orthodox Christians vs. Islamist militants and sectarian mob violence
Who: Coptic Orthodox Christians vs. Islamist militants, sectarian mobs, and discriminatory state/social structures.
Where: Egypt, especially Upper Egypt, Cairo, Alexandria, Minya, and Sinai.
Relevant period: 2006–2026, especially after the 2011 revolution and during ISIS-linked attacks.
What happened:
Egypt’s Coptic Orthodox community has faced church bombings, mob attacks, forced displacement, church-burning incidents, and recurring violence linked to rumors about conversion, interfaith relationships, blasphemy, or church construction. Carnegie’s analysis argues that anti-Coptic violence has to be understood not only as Muslim-Christian hostility but also through Egypt’s legal system, security failures, and authoritarian institutions. More recent reports continue to describe attacks on Coptic homes and churches, while ISIS and other jihadist groups have targeted Copts, especially in Sinai and major church bombings.
Religious dimension:
This is explicitly sectarian in many incidents, though often enabled by local politics, weak legal protection, and state mismanagement.
Best classification: Sectarian violence and jihadist attacks against an Orthodox Christian minority.
6. Ethiopia: Ethiopian Orthodox Christians and Muslims in local communal violence
Who: Ethiopian Orthodox Christians, Muslims, and other Christian groups.
Where: Ethiopia, especially areas with mixed Christian-Muslim populations.
Relevant period: 2006–2026, with periodic local violence.
What happened:
Ethiopia is a majority-Christian country with a large Ethiopian Orthodox population and a very large Muslim minority. The main recent wars in Ethiopia, such as the Tigray War, were not primarily Muslim-Christian conflicts. But Ethiopia has had recurring local Christian-Muslim tensions, including disputes over religious processions, mosques, churches, land, identity, and regional political competition. Recent scholarship has discussed emerging Muslim-Christian tensions in areas such as southern Wollo.
Religious dimension:
Often local and communal rather than national war. Religion overlaps with ethnicity, region, political competition, and local grievances.
Best classification: Localized communal religious tension, not a single national Orthodox-Muslim war.
7. Bosnia and Herzegovina / Republika Srpska tensions with Bosniak Muslims
Who: Bosnian Serbs, historically Serbian Orthodox, vs. Bosniaks, historically Muslim.
Where: Bosnia and Herzegovina, especially Republika Srpska.
Relevant period: The major war was 1992–1995, so outside the last 20 years, but its political afterlife remains active from 2006–2026.
What happened:
There has not been a new full-scale Orthodox-Muslim war in Bosnia in the last 20 years, but the unresolved legacy of the Bosnian War remains politically explosive. Republika Srpska leaders have repeatedly pushed separatist rhetoric and challenged Bosnia’s central institutions. In 2026, Bosnian Serbs again celebrated a banned holiday tied to the 1992 declaration that preceded the war, which remains discriminatory in the eyes of Bosnia’s Constitutional Court because of its association with exclusion of Bosniaks and Croats.
Religious dimension:
The 1990s war involved Serb Orthodox, Bosniak Muslim, and Croat Catholic identities, but the last 20 years are better described as postwar nationalist tension rather than active Orthodox-Muslim warfare.
Best classification: Post-conflict ethnic-national tension with religious identity markers.
8. Cyprus / Greek Orthodox Cypriots vs. Turkish Muslim Cypriots and Turkey
Who: Greek Orthodox Cypriots vs. Turkish Cypriots and Turkey.
Where: Cyprus.
Relevant period: The main war and division occurred in 1974, but the conflict remains unresolved.
What happened:
The island remains divided between the internationally recognized Republic of Cyprus, mostly Greek Orthodox, and the Turkish-backed north, mostly Turkish Muslim. In the last 20 years, this has mostly been a frozen conflict, diplomatic dispute, and property/recognition issue rather than an active war.
Religious dimension:
Greek Orthodox and Turkish Muslim identities matter historically and culturally, but the conflict is primarily nationalist, territorial, and geopolitical.
Best classification: Frozen ethno-national conflict.
Condensed list

Bottom line
The clearest Orthodox Christian vs. Muslim-related conflicts in the last 20 years are:
- Armenians vs. Azerbaijan over Nagorno-Karabakh.
- Russia vs. Islamist insurgents in the North Caucasus.
- Serbs vs. Kosovo Albanians in Kosovo.
- Syrian Orthodox Christians vs. ISIS/al-Nusra and other jihadists during the Syrian Civil War.
- Coptic Orthodox Christians vs. Islamist/sectarian violence in Egypt.
- Ethiopian Orthodox-Muslim local communal tensions, though less like a single war.
The important caution: in most cases, the conflict is not purely theological. Orthodoxy and Islam often function as civilizational, ethnic, and national identity markers, while the actual causes are usually territory, state power, nationalism, separatism, terrorism, demographic control, and historical grievance.
