Oil war

An oil war is a conflict centered on petroleum resources. These conflicts can involve the actual oil itself. They may also involve how oil is transported or consumed. Sometimes, these wars are about the regulation of petroleum products. An oil war can occur in regions with large oil reserves. It can also happen in places used for oil infrastructure. This includes locations meant for the production or transport of oil. The term can refer to general regional conflicts or specific historical wars.

There are several ways that oil might contribute to war. One pathway is through territorial conquest. Land containing oil can increase the rewards of taking that land. Another pathway involves market domination. For example, the Iraqi conquest of Kuwait led to the Gulf War. This created a risk that one entity might control the market. Oil wealth can also change how a government functions. It can make leaders less accountable to their own public. This might lower the risks for leaders who want to start wars.

Other mechanisms involve how oil wealth is used by different groups. Wealth from oil can help finance nonstate actors. These groups may use the money to start rebellions or civil wars. Conflicts can also arise from efforts to secure transit routes. States may fight to protect the paths used to move oil. Additionally, foreign workers in petrostates can sometimes motivate grievances. These grievances can lead to acts of terrorism, such as those by Al-Qaeda. Each of these pathways shows how energy resources interact with politics.

Scholars often debate how much oil actually causes these wars. Professor Emily Meierding has suggested that oil wars might be a myth. She argues that people overestimate the value of these conflicts. Proponents may underestimate how hard it is to seize foreign oil fields. Meierding examined four specific cases to test this idea. These included the Chaco War between Bolivia and Paraguay. She also studied the Iran-Iraq War and the Gulf War. Finally, she looked at Japan's attack on the Dutch East Indies during World War II.

In her research, Meierding found a specific pattern. In those four cases, oil was not the main cause of aggression. Control of additional oil resources was not the primary reason for fighting. However, newer research offers different perspectives on the issue. A 2024 study looked at how oil affects contested territory. It found that oil presence can make states less likely to seek land. Conversely, a 2026 study found a different trend regarding new resources. When a new fuel is claimable by multiple states, war likelihood increases.

History provides many examples of conflicts linked to petroleum. During World War I, from 1914 to 1918, some operations planned to secure oil. The Chaco War took place from 1932 to 1935. World War II, spanning 1939 to 1945, included a major oil campaign. The Biafran War, or Nigerian Civil War, occurred from 1967 to 1970. The Iran-Iraq War lasted from 1980 to 1988. The Gulf War took place between 1990 and 1991. The Iraq War occurred from 2003 to 2011.

These conflicts connect to many broader global systems. The study of oil wars relates to the concept of petro-aggression. It also connects to the idea of the resource curse. This is when resource wealth affects a nation's stability. Economic warfare is another related field of study. Issues like the 1973 oil crisis show how oil affects global markets. Territorial disputes, such as those in the South China Sea, also involve energy interests. Understanding these links helps explain how energy shapes history.
