Wars and Armed Conflicts have been an almost constant ocurrance throughout U.S. history. It seems there are always tyrants with a bulls eye painted on their heads that the U.S. Government is chasing (and using as a poster child to help finance the military complex). One of the best quotes of recent years was on a billboard in Houston, Texas. It was advertising an American Civil War exhibit at a local museum and simply asked: “What were we Thinking?” Now that pretty much sums it up…

18th  Century Wars and Armed Conflicts

Involving the U.S. (Total = 6)

Revolutionary War (1775-1783)

The American Revolution, also known as the U.S. War of Independence, lasted from 1775 to 1783. The conflict started from tensions and disagreements between residents of Great Britain’s 13 North American colonies and their colonial government, which was representing the British crown.


Chickamunga Wars (1776–1795)

The Chickamunga Wars lasted from 1776 to 1794 and were a continuation of the Cherokee (''Ani-Yunwiya'', ''Ani-Kituwa'', ''Tsalagi'', ''Talligewi'') struggles against encroachment into their territory (southwestern frontier territories of the United States) by American frontiersmen from the former British colonies. The conflict resulted in a series of ambushes, campaigns, minor skirmishes, raids and several full-scale frontier battles.


Northwest Indian War [also known as Little Turtle’s War] (1785–1793)

The Northwest Indian War was also known as Little Turtle's War lasted from 1785 to 1795. It was a between the United States and a confederation of numerous Native Indian tribes, with minor support from the British, for control of the Northwest Territory. It followed many years of conflict over this territory, first among Native American tribes, and then with the added shifting alliances among the tribes and the European powers: France, Great Britain, and their colonials.

Shays' Rebellion (1786–1787)

Shays’ Rebellion was fought during 1786 and 1787 in the Massachusetts countryside. It was a result of the monetary debt (economic) crisis that resulted from the American Revolutionary War. The Continental Army and state militia veterans received very little reimbursement for their military service. Continental Army Captain Daniel Shays led an armed uprising against debt collection in Massachusetts. Shays' Rebellion highlighted the weakness of the nation’s finances and the national government and forced a reform to the Articles of Confederation. The Philadelphia Convention of 1787 resulted in the Constitution of the United States and the election of George Washington as the first president of the United States.


Whiskey Rebellion (1791–1794)

The Whiskey Rebellion began in 1791 (possibly earlier) and lasted until 1794. It was an uprising of settlers in western Pennsylvania that were rebelling against liquor taxes. It was the first time that the new U.S. Federal government was able to establish federal authority by military means within state boundaries.


Quasi-War [Associated with the French Revolutionary Wars] (1798–1800)

The Quasi-War lasted from 1798 to 1800 and was an undeclared naval war between the United States and France while President John Adams was in office. It was escalated by the XYZ Affair and ended when French politics changed direction after Napoleon came into power.

19th  Century Wars and Armed Conflicts

Involving the U.S. (Total = 63)

First Barbary War [Associated with the Barbary Wars] (1801–1805)
The First Barbary War (1801–1805) was also known as the Tripolitanian War and the Barbary Coast War, and was the first of two Barbary Wars between the United States, Sweden and the four North African states known collectively as the "Barbary States". Three of these were nominal provinces of the Ottoman Empire, but in practice autonomous: Tripoli, Algiers, and Tunis. The fourth was the independent Sultanate of Morocco. The cause of the war was pirates from the Barbary States seizing American merchant ships and holding the crews for ransom, demanding the U.S. pay tribute to the Barbary rulers. United States President Thomas Jefferson refused to pay this tribute, in addition Sweden had been at war with the Tripolitans since 1800.


German Coast Uprising (1811)
The German Coast Uprising of 1811 was a revolt of black slaves in parts of the Territory of Orleans on January 8–10, 1811. The uprising occurred on the east bank of the Mississippi River in what are now St. John the Baptist and St. Charles Parishes, Louisiana. While the slave insurgency was the largest in US history, the rebels killed only two white men. Confrontations with militia and executions after trial killed 95 black people. White men led by officials of the territory formed militia companies to hunt down and kill the insurgents. Over the next two weeks, white planters and officials interrogated, tried and executed an additional 44 insurgents who had been captured. Executions were generally by hanging or firing squad, with some dismembering of the remains. Heads were displayed on pikes to intimidate other slaves.


Tecumseh's War (1811)

Tecumseh's War or Tecumseh's Rebellion was a conflict between the United States Army and an American Indian confederacy led by the Shawnee leader Tecumseh in the Indiana Territory. Although the war is often considered to have climaxed with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, Tecumseh's War essentially continued into the War of 1812, and is frequently considered a part of that larger struggle. The war lasted for two more years, until the fall of 1813, when Tecumseh, as well as second-in-command Roundhead died fighting Harrison's Army of the Northwest at the Battle of the Thames in Upper Canada, near present-day Chatham, Ontario, and his confederacy disintegrated. Tecumseh's War is viewed by some academic historians as being the final conflict of a longer term military struggle for control of the Great Lakes region of North America, encompassing a number of wars over several generations, referred to as the Sixty Years' War.


The Patriot War (1812-1814)

The Patriot War was an armed conflict that occurred before and during the War of 1812 in Spanish East Florida. The United States unwisely, covertly and illegally attempted to eradicate Spanish authority and control over East Florida and seize the territory. Since the Patriot War was fought on a regional scale and did not include any legendary generals or fabled battles it has been virtually forgotten in U.S. history. Florida was a Spanish colony during the time of the Patriot War and was divided into two sections: West and East Florida. When the War of 1812 began, the Madison administration withdrew its tacit support of the Patriots; Madison did not want Spain to ally with Great Britain in the larger conflict because of events in East Florida. The Patriot War was a military and political debacle that was embarrassing to the Madison Administration within the U.S. and was internationally discreditable to early U.S. foreign policy. The Madison administration used filibustering (19th century irregular military adventurers who claimed to be acting on behalf of U.S. interests while seeking and engaging in conflicts with nations in which the U.S. was at peace) and exploited boundary disputes between East Florida and Georgia in an attempt to seize Spanish territory.


 War of 1812 (1812–1815)

The War of 1812 was fought between the United States and Great Britain. The British restricted the American trade since they feared it was negatively effecting their ongoing war with France. They also wanted to set up an Indian state in the Midwest in order to maintain their influence in the region and prevent the United States from expanding westward. Contrary to popular belief, the United States did not win this war as in ended in a stalemate with the ratification of the Treaty of Ghent. No territory was lost or gained and it was bankrupting both nations.


Creek War (1813–1814)

The Creek War was fought from 1813 to 1814 and resulted in U.S. victory over Creek Indians, who were British allies during the War of 1812. The Shawnee leader Tecumseh, who expected British help in recovering hunting grounds lost to settlers, traveled to the south to warn of dangers to native cultures posed by whites. Factions arose among the Creeks, and a group known as the Red Sticks preyed upon white settlements and fought with those Creeks who opposed them. At the Treaty of Ft. Jackson on August 9, 1814 the Creeks were required to cede 23,000,000 acres of land, comprising more than half of Alabama and part of southern Georgia. Much of that territory belonged to Indians who had earlier been Jackson’s allies.


Second Barbary War [Associated with the Barbary Wars] (1815)
The Second Barbary War was fought from 1815 to 1816 and was the second of two wars fought between the United States and the North African Barbary states of Tripoli, Tunis, and Algeria. After the end of the war, the United States and European nations stopped their practice of paying tribute to the pirate states to forestall attacks on their shipping. It helped mark the beginning of the end of piracy in that region, which had been rampant in the days of Ottoman domination (16th to the 18th centuries). Within decades, European powers built ever more sophisticated and expensive ships which the Barbary pirates could not match in numbers or technology.


First Seminole War (1817–1818)

The First Seminole War erupted over forays staged by U.S. authorities to recapture runaway black slaves living among Seminole bands, who stiffly resisted. In 1818, Major General Andrew Jackson was dispatched with an army of more than 3,000 soldiers to Florida to punish the Seminole. After liquidating several native settlements, then executing two British traders (Arbuthnot and Ambrister) held for reportedly encouraging Seminole resolve, General Jackson captured the Spanish fort of Pensacola in May 1818 and deposed the government. However, he failed to snuff out Seminole opposition.


Texas-Indian Wars (1820–1875)

The Texas–Indian wars were a series of 19th-century conflicts between settlers in Texas and the Southern Plains Indians. These conflicts began when the first wave of European-American settlers moved into Spanish Texas.


Arikara War - The First Plains Indian War (1823)

Taking place in 1823, the Arikara War is noted as the first Plains Indian War between the United States and the western Native Americans. The Arikara, also known as the Arikaree or Ree Indians, were a semi-nomadic group who lived in tipis on the plains of South Dakota for several hundred years. Primarily an agricultural society, they were often bullied by their nomadic neighbors, especially the Sioux. Occupying a central location for trade between the Indians and the white settlers to the east, they also began to come into conflict with the many traders encroaching upon their lands.


Aegean Sea Anti-Piracy Operations (1825–1828)

Aegean Sea Anti-Piracy Operations began in 1825 when the United States government dispatched a squadron of ships to suppress Aegean Greek pirates. Due to the Greek civil wars and the decline of the Hellenic Navy, the Aegean quickly became a haven for pirates who sometimes doubled as privateers.


Winnebago War (1827)

The Winnebago War (also called the Winnebago Indian Disturbances of 1827) took place in Michigan Territory (now Wisconsin). The United States sent troops from Illinois and Michigan to the Prairie du Chien area where the Winnebago surrendered.


First Sumatran Expedition (1832)

The First Sumatran expedition, which featured the Battle of Quallah Battoo (Aceh: Kuala Batèë, Malay: Kuala Batu) in 1832, was a punitive expedition by the United States Navy against the village of Kuala Batee (id), presently a subdistrict in Southwest Aceh Regency.


Black Hawk War (1832)

The Black Hawk War was a brief conflict between the United States and Native Americans led by Black Hawk, a Sauk leader. The war erupted soon after Black Hawk and a group of Sauks, Meskwakis, and Kickapoos, known as the "British Band", crossed the Mississippi River, into the U.S. state of Illinois, from Iowa Indian Territory in April 1832. Black Hawk's motives were ambiguous, but he was apparently hoping to avoid bloodshed while resettling on tribal land that had been ceded to the United States in the disputed 1804 Treaty of St. Louis.


Second Seminole War (1835–1842)

The Second Seminole War began: December 23, 1835 and ended on August 14, 1842. It was fought between the United States and Seminole Indians of Florida. The Location of the Second Seminole War was in south and central Florida. The Second Seminole War resulted in the Seminole Indians being allowed to remain in South Florida, though some were encouraged to move West. In effect, the Army could not defeat the Seminoles, and they were allowed to remain in place.


Second Sumatran Expedition (1838)

The Second Sumatran expedition was a punitive expedition by the United States Navy against inhabitants of the island of Sumatra. After Malay warriors or pirates had massacred the crew of the American merchant ship Eclipse, an expedition of two American warships landed a force that defeated the Malays in two short engagements.


Mexican–American War (1846–1848)

The Mexican-American War, also called Mexican War, was fought between the United States and Mexico from 1846 to 1848.  It started after the United States’ annexation of Texas in 1845 and from a dispute over whether Texas ended at the Nueces River (Mexican claim) or the Rio Grande (U.S. claim). The war resulted in the United States’ acquisition of more than 500,000 square miles of Mexican territory.


Cayuse War (1847–1855)

After the Cayuse Indians killed 14 whites and held 53 others captive until ransomed [the Whitman Massacre], about 500 settlers took up arms and marched through Cayuse territory (southeast Washington and northeast Oregon), demanding the surrender of the warriors responsible for the crimes. US troops and militiamen from the Oregon territory were called in to suppress the Cayuse, who refused to make peace and raided settlements. Five captured Cayuse were tried and convicted of murder by a military commission and hanged on June 3, 1850. Bloodshed in the area continued until 1855, when the Indians were defeated and placed on a reservation with the Umatilla Indians. The Cayuse were greatly reduced in number by the war, and much of their tribal land was taken.


Apache Wars (1851–1900)

The Apache Wars were a series of armed conflicts between the United States Army and various Apache nations fought in the southwest between 1849 and 1886, though minor hostilities continued until as late as 1924. The United States inherited conflicts between settlers and Apache groups when Mexico ceded territory after the Mexican–American War in 1846. These conflicts continued as new United States citizens came into traditional Apache lands to raise livestock, crops and to mine minerals.


Puget Sound War (1855–1856)

The Puget Sound War was an armed conflict that took place in the Puget Sound area of the state of Washington in 1855–56, between the United States military, local militias and members of the Native American tribes of the Nisqually, Muckleshoot, Puyallup, and Klickitat.


First Fiji Expedition (1855)

The First Fiji Expedition undertaken by the United States occurred in October 1855 during the civil war on the islands. In response to the alleged arson attacks on the American commercial agent in Lautoka, Viti Levu, the navy sent a warship to demand compensation for the attack from Seru Epenisa Cakobau, the Vunivalu of Bau and self-proclaimed Tui Viti (King of Fiji).


Rogue River Wars (1855–1856)

The final Rogue River War began early on the morning of October 8, 1855, when self-styled volunteers attacked Native people in the Rogue River Valley. It ended in June 1856 with the removal of most of the Natives in southwestern Oregon to the Coast Reservation, which later became the Siletz Reservation. From 235 to 267 Indian people are thought to have been killed in the war, together with fifty soldiers, among them thirty-three volunteers and seventeen regular troops. By one account, Indians killed forty-four white civilians.


Third Seminole War (1855–1858)

The Third Seminole War (1855-1858) was over American encroachment on Seminole lands. The Seminole who were living in Florida at this time were refugees who had avoided removal to Oklahoma and were living in the Everglades. The war started when Billy Bowlegs retaliated against a crew of surveyors who had looted his camp.


Yakima War (1855–1858)

The Yakima War (1855-1858) was a conflict between the United States and the Yakama, a Sahaptian-speaking people of the Northwest Plateau, then part of Washington Territory. It took place in the southern interior of present-day Eastern Washington.

Navajo Wars (1858–1866)

The term Navajo Wars covers at least three distinct periods of conflict in the American West: the Navajo against the Spanish; the Navajo against the Mexican government; and the Navajo against the United States. These conflicts ranged from small-scale raiding to large expeditions mounted by governments into territory controlled by the Navajo. The Navajo Wars also encompass the widespread raiding that took place throughout the period; the Navajo raided other tribes and nearby settlements, who in return raided into Navajo territory, creating a cycle of raiding that perpetuated the conflict.


Second Fiji Expedition (1859)

The Second Fiji Expedition was an 1859 United States Navy operation against the native warriors of Seru Epenisa Cakobau on the island of Waya in Fiji.


John Brown's Raid on Harpers Ferry (1859)

The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States of America, who advocated for states’ rights to perpetual slavery and its expansion in the Americas.

Among the 34 U.S. states in February 1861, seven Southern slave states individually declared their secession from the U.S. to form the Confederate States of America, or the South. The Confederacy grew to include eleven states. The Confederacy was never diplomatically recognized by the United States government, nor was it recognized by any foreign country (although Britain and France granted it belligerent status).

Bluff War (1914–1915)

The Bluff War, also known as Posey War of 1915, or the Polk and Posse War, was one of the last armed conflicts between the United States and native Americans. It began in March 1914 and was the result of an incident between a Utah shepherd and Tse-ne-gat, the son of the Paiute Chief Narraguinnep ("Polk").

During the conflict, Germany, Austria-Hungary, Bulgaria and the Ottoman Empire (the Central Powers) fought against Great Britain, France, Russia, Italy, Romania, Japan and the United States (the Allied Powers). Thanks to new military technologies and the horrors of trench warfare, World War I saw unprecedented levels of carnage and destruction. By the time the war was over and the Allied Powers claimed victory, more than 16 million people—soldiers and civilians alike—were dead.


Russian Civil War (1917–1922)

The Russian Civil War (November 1917 – October 1922) was a multi-party war in the former Russian Empire immediately after the Russian Revolutions of 1917, as many factions vied to determine Russia's political future. The two largest combatant groups were the Red Army, fighting for the Bolshevik form of socialism led by Vladimir Lenin, and the loosely allied forces known as the White Army, which included diverse interests favoring monarchism, capitalism and alternative forms of socialism, each with democratic and antidemocratic variants.


Posey War (1923)

The Posey War, also known as the Last Indian Uprising and several other names, occurred in March 1923 and may be considered the final Indian War in American history. Though it was a minor conflict, it involved a mass exodus of Ute and Paiute native Americans from their land around Bluff, Utah to the deserts of Navajo Mountain. The natives were led by a chief named Posey, who took his people into the mountains to try and escape his pursuers. Unlike previous conflicts, posses played a major role while the United States Army played a minor one. The war ended after a skirmish at Comb Ridge. Posey was badly wounded and his band was taken to a prisoner-of-war camp in Blanding. When Posey's death was confirmed by the authorities, the prisoners were released and given land allotments to farm and raise livestock


World War II (1939–1945)

The instability created in Europe by the First World War (1914-18) set the stage for another international conflict–World War II–which broke out two decades later and would prove even more devastating. Rising to power in an economically and politically unstable Germany, Adolf Hitler and his National Socialist (Nazi Party) rearmed the nation and signed strategic treaties with Italy and Japan to further his ambitions of world domination. Hitler’s invasion of Poland in September 1939 drove Great Britain and France to declare war on Germany, and World War II had begun. Over the next six years, the conflict would take more lives and destroy more land and property around the globe than any previous war. Among the estimated 45-60 million people killed were 6 million Jews murdered in Nazi concentration camps as part of Hitler’s diabolical “Final Solution,” now known as the Holocaust.

Today approximately 76,000 people remain displaced within Lebanon. There was also a mass exodus of almost one million people from Lebanon as a result of the war. The government of Lebanon had been dominated by Maronite Christians. The link between politics and religion had been reinforced under the mandate of the French colonial powers from 1920 to 1943, and the parliamentary structure favored a leading position for the Christians. However, the country had a large Muslim population and many pan-Arabist and Left Wing groups which opposed the pro-western government.The establishment of the state of Israel and the displacement of a hundred thousand Palestinian refugees to Lebanon changed the demographic balance in favor of the Muslim population.

Intervention in the Somali Civil War (1992–1995)

The United States Army has a long tradition of humanitarian relief. No such operation has proven as costly or shocking, however, as that undertaken during the Intervention in the Somalia Civil War from August 1992 to March 1994. Greeted initially by Somalis happy to be saved from starvation, U.S. troops were slowly drawn into interclan power struggles and ill-defined "nation-building" missions. The American people woke up one day in early October 1993 to news reports of dozens of our soldiers killed or wounded in fierce fighting in the streets of the capital city Mogadishu. These disturbing events of a decade ago have taken on increasing meaning after the horrific attacks of 11 September 2001.

The main belligerents were the forces of the Republic of Bosnia and Herzegovina and those of the self-proclaimed Bosnian Serb and Bosnian Croat entities within Bosnia and Herzegovina, Republika Srpska and Herzeg-Bosnia, which were led and supplied by Serbia and Croatia, respectively.


Note: The Yugoslav Wars were a series of ethnically-based wars and insurgencies fought from 1991 to 1999/2001 in the former Yugoslavia. These wars accompanied and facilitated the breakup of the Yugoslav state, when its constituent republics declared independence, but the issues of ethnic minorities in the new countries (chiefly Serbs, Croats and Albanians) were still unresolved at the time the republics were recognized internationally. The wars are generally considered to be a series of separate but related military conflicts which occurred in, and affected, most of the former Yugoslav republics.


Kosovo War [Part of the Yugoslav Wars] (1998–1999)

The U.S. was supported initially by Canada and the United Kingdom and later by a coalition of over 40 countries, including all NATO members. The war's public aims were to dismantle al-Qaeda and to deny it a safe base of operations in Afghanistan by removing the Taliban from power. The War in Afghanistan is the longest war in United States history.


Note: The terrorist attacks in the US on on September 11, 2001 ultimately resulted in the US declaring and waging a War on Terror. Osama Bin Laden was eventually tracked down and killed some 10 years later. But the way the war on terror has been conducted has led to many voicing concerns about the impact on civil liberties, the cost of the additional security focused changes, the implications of the invasions and wars in Iraq and Afghanistan, and more.


Iraq War [Part of the Iraqi Insurgency and War on Terror] (2003–2011)

The Iraq Waralso known as the Second Gulf 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.

Note: The Iraqi Insurgency began  in Iraq after the 2003 US-led invasion, and lasted throughout the ensuing Iraq War (2003–2011).

Libyan Civil War [Part of the Libyan Crisis] (2011)
The first Libyan Civil War, also referred to as the Libyan Revolution or 17 February Revolution, was an armed conflict in 2011, in the North African country of Libya, fought between forces loyal to Colonel Muammar Gaddafi and those seeking to oust his government.


Note: The Libyan Crisis seized the attention of the international community and has been labeled a clear case for when timely and decisive response to uphold RtoP in the face of an imminent threat of mass atrocities should occur. In February 2011, civilians began to undertake political protests demanding an end to Libyan leader Muammar Gaddafi’s 41-year reign, wherein protestors found themselves the target of mass atrocities at the hands of government armed forces. In witnessing such violence by the Libyan government, the international community and regional and sub-regional bodies acted to protect the populations through a range of economic, political, and military measures.

Note: The Boko Haram Insurgency began in 2009, when the jihadist rebel group Boko Haram started an armed rebellion against the government of Nigeria. In 2012, tensions within Boko Haram resulted in gradual split of the group between Salafist conservative faction led by Abu Usmatul al-Ansari, and the more dominant, violent faction led by Abubakar Shekau. By 2015, part of the group split into al-Qaeda affiliated Ansaru, and Shekau's faction became ISIL's West Africa branch.


War in Afghanistan (2015–present)

The War in Afghanistan (2015–present) refers to the period of the war in Afghanistan following the US-led 2001–2014 phase. The U.S.-led war followed the September 11 attacks, aiming to attack al-Qaeda and deny it a safe haven in Afghanistan by removing the Taliban from power.
