Source: War and Peace: History of the U.S. in Armed Conflict



The editors at Best Liberal Arts Colleges decided to research the topic of: WAR AND PEACE For nearly half of its relatively brief existence, the United States has been actively involved in armed conflict, whether at home or abroad. Here is a closer look at wars involving the U.S. military. When we've fought and who we've fought Timeline of U.S. history with length and time period of wars plotted, so people can see clearly what decades have actually been peaceful.

- War - Length - Years - Fought against

- American Revolution - 8 - 1775-1783 - Great Britain

- First Barbary War - 4 - 1801-1805 - Tripoli, Algiers, Morocco

- War of 1812 - 3 - 1812-1815 - Great Britain/Canada

- Second Barbary War - .5 - 1815 - Tripoli, Tunis, Algeria

- War with Mexico - 2 - 1846-48 - Mexico

- Iraq War - 8 - 2003-2011 - Iraq, insurgent groups Afghanistan really our longest war? The longest continuous war in U.S. history, depending on whom you ask, is the current war in Afghanistan. However, it can be argued that the Vietnam War was far longer. Why the confusion? The U.S. never officially declared war on North Vietnam, Laos or Cambodia, and heavy U.S. fighting didn't start until the '60s.

- Afghanistan

- October 7, 2001-present - 11+ years

- Vietnam, if it started with troop training in 1955

- Nov. 1, 1955-April 30, 1975 - 19 years

- Vietnam, if it started with the Gulf of Tonkin incident in 1964
