Ethnic wars are armed conflicts fought between or among ethnic groups that share common cultural characteristics such as language, history, beliefs, and values, within a defined territory. These wars arise from ethnic rivalries, identity-based grievances, or competition for power and resources. Ethnic conflict may occur between groups within a state or between an ethnic group and the state itself, especially when the state marginalises or excludes that group.

Civil wars differ in that they involve conflicts among groups within a population and arise from factors beyond ethnic interests. Civil wars involve organised, large-scale violence carried out through collective action, resulting in massive killings, destruction of property, and displacement. However, many civil wars in African countries such as Rwanda, Burundi, and Somalia are closely linked to ethnic problems, showing that ethnic and civil wars are often interrelated.

The nature of these conflicts includes:

• Large-scale, sustained, organised armed conflicts within a state's borders, where the state is a principal combatant
• Ethnic conflict specifically centres on ethnic identity as the primary driver of violence
• Involvement of insurgent groups, militias, and government forces

Key characteristics include:

1. Wars between organised groups within the same state, aiming to take control of the country or a region, achieve independence, or change government policies
2. Collective acts of violence resulting in mass killings, destruction of property, and displacement of people
3. Decentralised insurgencies using unconventional methods of fighting, including terrorism
4. Blurred lines between fighters and civilians, with individuals sometimes becoming perpetrators to settle personal disputes
5. Fixed ethnic identities that make compromise difficult, as ethnic identity is often perceived as more fixed than ideological identity

The Kosovo Conflict (1998-1999)

The Kosovo conflict began in 1989 when Serbian President Slobodan Milosevic ended Kosovo's autonomous status within Serbia. The Albanian majority in Kosovo, predominantly Muslim (93.5% of the population), resented this decision and initially organised passive resistance under Professor Ibrahim Rugova. When passive resistance failed, the Kosovo Liberation Army (UÇK) launched an armed campaign in 1997. Serbian forces responded with mass displacement and atrocities against the Albanian population.

NATO intervened in 1998 with an air campaign, forcing Serbian forces to withdraw by June 1999. The conflict involved systematic violence planned by the ruling authority, with Serbian security forces carrying out violence against the Kosovo Albanian community. The war attracted regional and global forces—NATO, the EU, and the UN—because it threatened Eastern European security and posed an immigration threat to EU countries.

Rwanda and Burundi Civil Wars

Both Rwanda and Burundi experienced severe ethnic conflicts in the early 1990s. The roots lie in colonial legacies: during the German and Belgian colonial periods, the Tutsi minority was favoured for administrative and leadership roles, creating deep divisions with the Hutu majority. The Belgian administration institutionalised these differences by issuing ethnic identity cards.

In Rwanda, the civil war began in 1990 when the Rwandan Patriotic Front (RPF), composed of Tutsi exiles, launched an invasion from Uganda. The genocide followed on 7th April 1994 after President Habyarimana's plane was shot down, with Hutu militias (Interahamwe) carrying out mass killings of Tutsis and moderate Hutus. Over 800,000 people were killed in just 100 days.

Burundi experienced similar cycles of violence, including the assassination of democratically elected President Melchior Ndadaye in 1993 and subsequent civil war. The Arusha Accords of 2000 eventually established a power-sharing system between Hutus and Tutsis.

The Somali Conflict

Somalia's conflict stems from clan-based divisions that intensified under General Mohamed Siad Barre's authoritarian rule (1969-1991). Barre favoured his own Marehan clan and allied clans (the "MOD coalition"), marginalising other clans including the Dir, Isaq, Darood, Hawiye, and Rahanweyn.

By 1991, Barre was overthrown, but his departure unleashed fresh cycles of violence as competing clans and warlords vied for control. The conflict created a devastating humanitarian crisis, prompting international intervention through UN missions and Operation Restore Hope (1992-1993). Somalia remains divided into federal member states, with some declaring semi-autonomy.

The Rohingya Conflict

The Rohingya, a Muslim ethnic group in Myanmar's Rakhine State, have faced systematic persecution since 1962 when General Ne Win seized power. The 1982 Citizenship Law effectively denied them nationality, leaving them stateless without legal protection.

Violence intensified in 2017 when the Arakan Rohingya Salvation Army (ARSA) attacked police posts. Myanmar's military response caused mass displacement, with hundreds of thousands fleeing to Bangladesh. International organisations condemned these actions as ethnic cleansing and genocide. An estimated 6,700 Rohingya were killed in 2017 alone, with mass graves confirming systematic killings.

The Mali Conflict

Mali's conflict is rooted in colonial legacies and ethnic marginalisation. The Tuareg people, inhabiting the northern deserts, were politically and economically marginalised under French rule and after independence. They formed the National Movement for the Liberation of Azawad (MNLA) in 2011, demanding autonomy for their homeland called Azawad.

The 2012 military coup enabled Tuareg insurgents and Islamic militant groups (including Al-Qaeda in the Islamic Maghreb) to control the north. French forces launched Operation Serval in January 2013, driving militants from major cities. The conflict illustrates how colonial manipulation of ethnicity continues to shape post-independence conflicts.

The Central African Republic (CAR) Civil War

CAR has experienced repeated coups and civil conflict since independence in 1960. The civil war intensified when President François Bozizé seized power in 2003. The conflict involved the Seleka (predominantly Muslim rebel groups) and Christian anti-Balaka militias, creating a cycle of revenge killings between religious communities.

The conflict caused massive displacement—over one million people displaced, with 750,000 refugees fleeing to neighbouring countries. The UN established MINUSCA in 2014 to protect civilians and support the transitional government. International peacekeepers from France (Operation Sangaris) also intervened.

The Yemen Civil War

Yemen's civil war began in 2014 when Houthi forces took control of the capital, Sanaa, expanding through southern provinces. The conflict involves multiple factions with international support—Iran backing the Houthis, while Saudi Arabia, the US, and Western countries support the recognised government.

The war caused massive casualties, destroyed infrastructure, and created a humanitarian crisis. The conflict became entangled with regional rivalries between Iran and Saudi Arabia, threatening international waterways in the Red Sea and drawing major powers into the dispute.

The Israeli-Palestinian Conflict

This conflict is rooted in British colonial policies, particularly the 1917 Balfour Declaration supporting a Jewish national home in Palestine. Since Israel's creation in 1948, the conflict has involved multiple wars (1967 Six-Day War, 1973 Yom Kippur War), intifadas, and ongoing violence.

The conflict threatens global peace and security because it involves religious claims to Jerusalem (holy to Judaism, Christianity, and Islam), attracts international actors with economic and geostrategic interests in Middle Eastern oil and gas, and draws major powers into supporting opposing sides. The US provides diplomatic, military, and economic support to Israel, while Iran and Arab nations support Palestinian groups.

These conflicts threaten global peace and security in several ways:

1. Regional instability: Conflicts in one country often spill over into neighbouring states, creating refugee crises and destabilising entire regions (e.g., the Great Lakes region of Africa)

2. Humanitarian crises: Mass displacements, famine, and disease affect millions, requiring international intervention and straining global resources

3. Intervention by major powers: External actors become involved, either directly or through proxies, escalating conflicts to regional or global levels (e.g., NATO in Kosovo, French forces in Mali)

4. Proliferation of weapons: The global military-industrial complex supplies weapons to warring factions, prolonging conflicts and making peace negotiations more difficult

5. Terrorism and extremism: Civil wars create conditions for terrorist organisations to flourish (e.g., Al-Qaeda in the Islamic Maghreb in Mali, al-Shabaab in Somalia)

6. Economic disruption: Conflicts disrupt trade routes, damage infrastructure, and create economic instability that affects global markets

7. Erosion of international norms: Mass atrocities, genocide, and ethnic cleansing challenge international humanitarian law and the responsibility to protect civilians

Ethnic and civil wars represent complex conflicts driven by historical grievances, identity politics, competition for resources, and struggles for power. Their characteristics—large-scale violence, displacement, blurred lines between combatants and civilians, and the involvement of external actors—make them particularly destructive and difficult to resolve. These conflicts pose significant threats to world peace and security through regional destabilisation, humanitarian crises, international intervention, and the proliferation of weapons. Understanding their nature is essential for developing effective peacebuilding strategies and promoting global stability.

In Tanzania, understanding ethnic and civil wars is relevant to everyday life in several practical ways. For example, when Tanzanians follow news about conflicts in neighbouring countries like Burundi or the Democratic Republic of Congo, this knowledge helps them understand why refugees flee to Tanzania (such as the hundreds of thousands hosted in camps like Nduta and Mtendeli), and how these inflows affect local communities, resource distribution, and security. Additionally, Tanzania's own history of peaceful transitions and ethnic coexistence, maintained through institutions like the Union of Tanganyika and Zanzibar, demonstrates that the conflict management strategies learned from studying these wars can inform national policies on unity, governance, and conflict prevention that directly affect citizens' daily lives and national stability.
