1. Gulf War:
The Gulf War (2 August 1990 – 28 February 1991), codenamed Operation Desert Shield (2 August 1990 – 17 January 1991) for operations leading to the buildup of troops and defense of Saudi Arabia and Operation Desert Storm (17 January 1991 – 28 February 1991) in its combat phase, was a war waged by coalition forces from 35 nations led by the United States against Iraq in response to Iraq's invasion and annexation of Kuwait. The great majority of the coalition's military forces were from the US, with Saudi Arabia, the United Kingdom and Egypt as leading contributors, in that order. More details
2. Falklands War:
The Falklands War was a ten-week war between Argentina and the United Kingdom over two British dependent territories in the South Atlantic: the Falkland Islands, and its territorial dependency, the South Georgia and the South Sandwich Islands. It began on Friday, 2 April 1982, when Argentina invaded and occupied the Falkland Islands (and, the following day, South Georgia and the South Sandwich Islands) in an attempt to establish the sovereignty it had claimed over them. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. More details
3. World War II:
World War II was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. More details
4. World War I:
World War I was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as the "war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. An estimated nine million combatants and seven million civilians died as a direct result of the war, and it also contributed to later genocides and the 1918 influenza pandemic, which caused between 50 and 100 million deaths worldwide.

5. Vietnam War:
The Vietnam War was a conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China, and other communist allies; the South Vietnamese army was supported by the United States, South Korea, the Philippines, Australia, Thailand and other anti-communist allies. The war is considered a Cold War-era proxy war by some US perspectives. More details
6. Korean War:
The Korean War (25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea following a series of clashes along the border. The United Nations Security Council authorized the formation and dispatch of UN forces to Korea to repel what was recognized as a North Korean invasion. Twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing around 90% of the military personnel. More details
7. Soviet Afghan War:
The Soviet–Afghan War lasted over nine years, from December 1979 to February 1989. Insurgent groups known collectively as the mujahideen, as well as smaller Maoist groups, fought a guerrilla war against the Soviet Army and the Democratic Republic of Afghanistan government, mostly in the rural countryside. The mujahideen groups were backed primarily by the United States, Saudi Arabia, and Pakistan, making it a Cold War proxy war. Between 562,000 and 2,000,000 civilians were killed and millions of Afghans fled the country as refugees, mostly to Pakistan and Iran. More details
8. Iraq War:
The Iraq War was a protracted armed conflict that began in 2003 with the invasion of Iraq by a United States-led coalition that overthrew the government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the occupying forces and the post-invasion Iraqi government. An estimated 151,000 to 600,000 or more Iraqis were killed in the first 3–4 years of conflict. The U.S. became re-involved in 2014 at the head of a new coalition; the insurgency and many dimensions of the civil armed conflict continue. More details
The Kosovo War was an armed conflict in Kosovo that started in late February 1998 and lasted until 11 June 1999. It was fought by the forces of the Federal Republic of Yugoslavia (by this time, consisting of the Republics of Montenegro and Serbia), which controlled Kosovo before the war, and the Kosovo Albanian rebel group known as the Kosovo Liberation Army (KLA), with air support from the North Atlantic Treaty Organisation (NATO) from 24 March 1999, and ground support from the Albanian army. The war ended with the Kumanovo Treaty. More details
The American Civil War was a war fought in the United States (U.S.) from 1861 to 1865. The Civil War is the most studied and written about episode in U.S. history. Largely as a result of the long-standing controversy over the enslavement of black people, war broke out in April 1861, when secessionist forces attacked Fort Sumter in South Carolina, shortly after United States President Abraham Lincoln was inaugurated. The loyalists of the Union in the North proclaimed support for the Constitution. They faced secessionists of the Confederate States in the South, who advocated for states' rights to uphold slavery.
