This is the list of military invasions that occurred or are still ongoing in the 21st century. So far, there have been 11 military invasions during the 21st century.
The Ethiopian National Defense Force (ENDF) is the military force of Ethiopia. Civilian control of the military is carried out through the Ministry of Defense, which oversees the Ground Forces, Air Force, Naval Force as well as the Defense Industry Sector.

Isaias Afwerki is an Eritrean politician and partisan who has been the president of Eritrea since shortly after he led the Eritrean People's Liberation Front (EPLF) to victory on 24 May 1991, ending the 30-year-old war for independence from Ethiopia. In addition to being president, Isaias has been the chairman of Eritrea's sole legal political party, the People's Front for Democracy and Justice (PFDJ). As Eritrea has never had a functioning constitution, no elections, no legislature and no published budget, Isaias has been the sole power in the country, controlling its judiciary and military. Hence, scholars and historians have long considered him to be a dictator, described his regime as totalitarian, by way of forced conscription; the United Nations and Amnesty International cited him for human rights violations. In 2022, Reporters Without Borders ranked Eritrea, under the government of Isaias, last out of 180 countries in its Press Freedom Index. In 2023 Eritrea ranked 174th out of 180 countries on the Press Freedom Index.
The Ogaden War, also known as the Ethio-Somali War, was a military conflict fought between Somalia and Ethiopia from July 1977 to March 1978 over the sovereignty of Ogaden. Somalia's invasion of the region, precursor to the wider war, met with the Soviet Union's disapproval, leading the superpower to end its support for Somalia to fully support Ethiopia instead.
The Ogaden National Liberation Front is a social and political movement, founded in 1984 to campaign for the right to self-determination for Somalis in the Ogaden or Somali Region of Ethiopia. Its armed wing, led by Ogaden national army waged an insurgency against the Ethiopian government from 1994 to 2018.
The Ethiopian occupation of Somalia, also called the Ethiopian invasion of Somalia or the Ethiopian intervention in the Somali Civil War, was an armed conflict that lasted from late 2006 to early 2009. It began when military forces from Ethiopia, supported by the United States, invaded Somalia to depose the Islamic Courts Union (ICU) and install the Transitional Federal Government (TFG). The conflict continued after the invasion when an anti-Ethiopian insurgency emerged and rapidly escalated. During 2007 and 2008, the insurgency recaptured the majority of territory lost by the ICU.
The Ethiopian–Somali conflict is a territorial and political dispute between Ethiopia, Somalia, and insurgents in the area, Originating in the 1300s, the conflict's most recent iteration began in the late 1940s when the Somali-inhabited Ogaden region was handed back to Ethiopia by the British. In the years following, tensions culminated in numerous insurgencies and several wars. However, because of the Somali Civil War and the lack of a functioning central government since the collapse of the Democratic Republic of Somalia in 1991, Ethiopia has the upper hand militarily and economically.
The Somali Rebellion was the beginning of the civil war in Somalia that occurred in the 1980s and early 1990s. The rebellion started in 1978 when President Siad Barre began using his special forces, the "Red Berets", to attack clan-based dissident groups opposed to his regime. The dissidents had been becoming more powerful for nearly a decade following his abrupt switch of allegiance from the Soviet Union to the United States and the disastrous 1977-78 Ogaden War.
The military history of Ethiopia dates back to the foundation of early Ethiopian Kingdoms in 980 BC. Ethiopia has been involved in many of the major conflicts in the horn of Africa, and was one of the few native African nations which remained independent during the Scramble for Africa, managing to create a modern army. 19th and 20th century Ethiopian Military history is characterized by conflicts with the Dervish State, Mahdist Sudan, Egypt, and Italy, and later by a civil war.
The 2007–2008 Ethiopian crackdown in Ogaden was a military campaign by the Ethiopian Army against the Ogaden National Liberation Front (ONLF). The crackdown against the guerrillas began after they killed 74 people in an attack on a Chinese-run oil exploration field in April 2007.
The Insurgency in Ogaden was an armed conflict that took place from 1994 to 2018. It was fought by separatists, the Ogaden National Liberation Front (ONLF), against the Ethiopian government. The war began in 1994, when the ONLF tried to separate Ethiopia's Somali Region from Ethiopia. It ended in a peace agreement as part of Prime Minister Abiy Ahmed's reforms.
The 1982 Ethiopian–Somali Border War occurred between June and August 1982 when Ethiopia, sending a 10,000 man invasion force backed by warplanes and armored units, supported by thousands of Somali Salvation Democratic Front (SSDF) rebels invaded central Somalia.
Abdullahi Ahmed Irro, also known as Abdullahi Ahmed Yusuf Irro, was a prominent Somali military professor and general. He helped establish the National Academy for Strategy.
Ethiopia–Somalia relations are bilateral relations between Ethiopia and Somalia. These relations are characterized by the land border shared by the two countries and a number of military conflicts in past years.
The 1964 Ethiopian–Somali Border War, also known as the First Ogaden War marked the first military conflict between the newly established Somali Republic and the Ethiopian Empire, lasting from February to April 1964. The border conflict was preceded by a rebellion in Ethiopia's Ogaden region, inhabited primarily by the Ogaden and other Somali clans, which began in mid-1963, shortly after Somalia's independence and unification of the two Somaliland colonies. Irredentist ambitions towards achieving further unity in the form of Greater Somalia led to encouragement and support for the Ogaden insurgency. The subsequent suppression of insurgents and increasingly harsh reprisals carried out by Emperor Haile Selassie's government resulted in a rapid decline in Ethio-Somali relations, eventually leading to direct confrontation between both governments' armed forces.
This is the military history of the 2020s.
The fall of the Derg, also known as Downfall of the Derg, was a military campaign that resulted in the defeat of the ruling Marxist–Leninist military junta, the Derg, by the rebel coalition Ethiopian People's Revolutionary Democratic Front (EPRDF) on 28 May 1991 in Addis Ababa, ending the Ethiopian Civil War. The Derg took power after deposing Emperor Haile Selassie and the Solomonic dynasty, an imperial dynasty of Ethiopia that began in 1270. The Derg suffered from insurgency with different factions, and separatist rebel groups since their early rule, beginning with the Ethiopian Civil War. The 1983–1985 famine, the Red Terror, and resettlement and villagization made the Derg unpopular with the majority of Ethiopians tending to support insurgent groups like the Tigray People's Liberation Front (TPLF) and Eritrean People's Liberation Front (EPLF).
The 1995 Ethiopian Federal Constitution formalizes an ethnic federalism law aimed at undermining long-standing ethnic imperial rule, reducing ethnic tensions, promoting regional autonomy, and upholding unqualified rights to self-determination and secession in a state with more than 80 different ethnic groups. But the constitution is divisive, both among Ethiopian nationalists who believe it undermines centralized authority and fuels interethnic conflict, and among ethnic federalists who fear that the development of its vague components could lead to authoritarian centralization or even the maintenance of minority ethnic hegemony. Parliamentary elections since 1995 have taken place every five years since enactment. All but one of these have resulted in government by members of the Ethiopian People's Revolutionary Democratic Front (EPRDF) political coalition, under three prime ministers. The EPRDF was under the effective control of the Tigray People's Liberation Front (TPLF), which represents a small ethnic minority. In 2019 the EPRDF, under Abiy, was dissolved and he inaugurated the pan-ethnic Prosperity Party which won the 2021 Ethiopian Election, returning him as prime minister. But both political entities were different kinds of responses to the ongoing tension between constitutional ethnic federalism and the Ethiopian state's authority. Over the same period, and all administrations, a range of major conflicts with ethnic roots have occurred or continued, and the press and availability of information have been controlled. There has also been dramatic economic growth and liberalization, which has itself been attributed to, and used to justify, authoritarian state policy.
... If the collapse of the USSR was sudden and largely bloodless, growing strains between its two largest successors would develop into limited fighting in the Donbas in 2014 and then into all-out warfare in 2022, causing death, destruction, and a refugee crisis on a scale not seen in Europe since the Second World War.
... However, the scale of Russia's invasion of Ukraine is unprecedented in modern history and, in terms of human costs, is Moscow's largest military intervention in the post-1945 period. ...
... . Russia had done the unthinkable, deliberately starting the biggest war in Europe since World War II. ...
The Washington Post's Pauline Jelinek, citing anonymous sources, described U.S. Special Forces accompanying Ethiopian troops. CBS news revealed that U.S. Air Force gunships were active over southern Somalia during the Ethiopian blitz. Through all the reporting, U.S. officials remained vague or silent on the subject of Washington's involvement. All the same, evidence was mounting that the U.S. had played a leading role in the Ethiopian invasion.
