Although the term "guerrilla warfare" was coined in the context of the
Peninsular War in the 19th century, the tactical methods of guerrilla warfare have long been in use. In the 6th century BC,
Sun Tzu proposed the use of guerrilla-style tactics in ''
The Art of War''. The 3rd century BC Roman general
Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the
Fabian strategy. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance against invading or occupying armies.
Guerrilla tactics focus on avoiding head-on confrontations with enemy armies, typically due to inferior arms or forces, and instead engage in limited skirmishes with the goal of exhausting adversaries and forcing them to withdraw. Due to this, guerrilla tactics are rarely used for anything other than defence. Organized guerrilla groups often depend on the support of either the local population or foreign backers who sympathize with the guerrilla group's efforts.
Etymology
The Spanish word is the diminutive form of ('war'). The term became popular during the early-19th century
Peninsular War, when, after the defeat of their regular armies,
the Spanish and Portuguese people successfully rose against the
Napoleonic
Napoleon Bonaparte ; it, Napoleone Bonaparte, ; co, Napulione Buonaparte. (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French military commander and political leader who ...
troops and defeated a highly superior army using the guerrilla strategy. In correct
Spanish usage, a person who is a member of a unit is a () if male, or a (
">eriˈʎeɾa if female.
The term ''guerrilla'' was used in English as early as 1809 to refer to the individual ''fighters'' (e.g., "The town was taken by the guerrillas"), and also (as in Spanish) to denote ''a group or band'' of such fighters. However, in most languages ''guerrilla'' still denotes the specific style of warfare. The use of the

A diminutive is a root word that has been modified to convey a slighter degree of its root meaning, either to convey the smallness of the object or quality named, or to convey a sense of intimacy or endearment. A (abbreviated ) is a word-formati ...
evokes the differences in number, scale, and scope between the guerrilla army and the formal, professional army of the state.
History
Prehistoric tribal warriors presumably employed guerrilla-style tactics against enemy tribes. Evidence of
conventional warfare, on the other hand, did not emerge until 3100 BC in Egypt and Mesopotamia.
The Chinese general and strategist
Sun Tzu, in his ''
The Art of War'' (6th century BC), became one of the earliest to propose the use of guerrilla warfare.
[Leonard, Thomas M., ''Encyclopedia of the developing world'', 1989, p. 728. "One of the earliest proponents of guerrilla war tactics is the Chinese master of warfare, Sun Tzu."] This inspired developments in modern guerrilla warfare.
In the 3rd century BC,
Quintus Fabius Maximus Verrucosus, widely regarded as the "father of guerrilla warfare",
devised the
Fabian strategy, which the
Roman Republic used to great effect against
Hannibal
Hannibal (; xpu, 𐤇𐤍𐤁𐤏𐤋, ''Ḥannibaʿl''; 247 – between 183 and 181 BC) was a Carthaginian general and statesman who commanded the forces of Carthage in their battle against the Roman Republic during the Second Puni ...
's army. This strategy would influence guerrilla tactics into the modern era.
In the
medieval Roman Empire, guerrilla warfare was frequently practiced between the eighth through tenth centuries along the eastern frontier with the Umayyad and then Abbasid caliphates. Tactics involved a heavy emphasis on reconnaissance and intelligence, shadowing the enemy, evacuating threatened population centres, and attacking when the enemy dispersed to raid. In the later tenth century this form of warfare was codified in a military manual known by its later Latin name as ''
De velitatione bellica'' ('On Skirmishing') so it would not be forgotten in the future.
Since
the Enlightenment, ideologies such as
nationalism,
liberalism,
socialism, and
religious fundamentalism have played an important role in shaping insurgencies and guerrilla warfare.

Kerala Varma (Pazhassi Raja) (1753-1805) used guerrilla techniques in his war against the British
East India Company in India between 1790 and 1805.
Arthur Wellesley adopted the term "guerrilla" into
English from Spanish usage in 1809, after the Pazhassi revolt against the British. Arthur Wellesley (in India 1797-1805) had commanded forces assigned to defeat Pazhassi's techniques, but failed.
The Moroccan military leader
Abd el-Krim ( - 1963) and his father unified the Moroccan tribes under their control and took up arms against the Spanish and French invaders in 1920. For the first time in history,
tunnel warfare was used alongside modern guerrilla tactics, which caused considerable damage to both the colonial armies in Morocco.
In the early 20th century
Michael Collins and
Tom Barry both developed many tactical features of guerrilla warfare during
the guerrilla phase of the 1919-1921 Irish War of Independence. Collins developed mainly
urban guerrilla-warfare tactics in
Dublin city (the Irish capital). Operations in which small
Irish Republican Army (IRA) units (3 to 6 guerrillas) quickly attacked a target and then disappeared into civilian crowds frustrated the British enemy. The best example of this occurred on
Bloody Sunday (21 November 1920), when Collins's assassination unit, known as
"The Squad", wiped out a group of British intelligence agents ("the

In west
County Cork, Tom Barry was the commander of the IRA
West Cork brigade. Fighting in west Cork was rural, and the IRA fought in much larger units than their fellows in urban areas. These units, called "

The
Algerian Revolution
The Algerian War, also known as the Algerian Revolution or the Algerian War of Independence,( ar, الثورة الجزائرية '; '' ber, Tagrawla Tadzayrit''; french: Guerre d'Algérie or ') and sometimes in Algeria as the War of 1 November ...
of 1954 started with a handful of Algerian guerrillas. Primitively armed, the guerrillas fought the French for over eight years. This remains a prototype for modern insurgency and counterinsurgency, terrorism, torture, and asymmetric warfare prevalent throughout the world today. In South Africa, African National Congress (ANC) members studied the Algerian War, prior to the release and apotheosis of Nelson Mandela; in their intifada against Israel, Palestinian fighters have sought to emulate it. Additionally, the tactics of Al-Qaeda closely resemble those of the Algerians.
The Mukti Bahini (Bengali: মুক্তিবাহিনী, translates as 'freedom fighters', or liberation army), also known as the Bangladesh Forces, was the guerrilla resistance movement consisting of the Bangladeshi military, paramilitary and civilians during the War of Liberation that transformed East Pakistan into Bangladesh in 1971. An earlier name Mukti Fauj was also used.
Strategy, tactics and methods
Strategy
Guerrilla warfare is a type of
asymmetric warfare: competition between opponents of unequal strength. It is also a type of irregular warfare: that is, it aims not simply to defeat an invading enemy, but to win popular support and political influence, to the enemy's cost. Accordingly, guerrilla
strategy
Strategy (from Greek στρατηγία ''stratēgia'', "art of troop leader; office of general, command, generalship") is a general plan to achieve one or more long-term or overall goals under conditions of uncertainty. In the sense of the "art ...
aims to magnify the impact of a small, mobile force on a larger, more-cumbersome one. If successful, guerrillas weaken their enemy by
attrition, eventually forcing them to withdraw.
Tactics
Tactically, guerrillas usually avoid confrontation with large units and formations of enemy troops but seek and attack small groups of enemy personnel and resources to gradually deplete the opposing force while minimizing their own losses. The guerrilla prizes mobility, secrecy, and surprise, organizing in small units and taking
advantage of terrain
An advantage of terrain occurs when military personnel gain an advantage over an enemy by using or simply in spite of, the terrain around them. The term does not exclusively apply to battles and can be used more generally regarding entire campaig ...
that is difficult for larger units to use. For example,
Mao Zedong summarized basic guerrilla tactics at the beginning of the
Chinese Civil War as:
"The enemy advances, we retreat; the enemy camps, we harass; the enemy tires, we attack; the enemy retreats, we pursue."
At least one author credits the ancient Chinese work ''
The Art of War'' with inspiring Mao's tactics.
In the 20th century, other communist leaders, including North Vietnamese
Ho Chi Minh, often used and developed guerrilla warfare tactics, which provided a model for their use elsewhere, leading to the Cuban "
foco" theory and the anti-
Soviet Mujahadeen in
Afghanistan.
[McNeilly, Mark. ''Sun Tzu and the Art of Modern Warfare'', 2003, p. 204. "American arming and support of the anti-Soviet Mujahadeen in Afghanistan is another example."]
Unconventional methods
In addition to traditional military methods, guerrilla groups may rely also on destroying infrastructure, using
improvised explosive devices, for example. They typically also rely on
logistical

and use of force.
The opposing army may come to suspect all civilians as potential guerrilla backers.
Many guerrilla movements today also rely heavily on children as combatants, scouts, porters, spies, informants, and in other roles. It has drawn international condemnation. Many states also
recruit children into their armed forces.
Some guerrilla groups also use
refugees as weapons
"Refugees as weapons", or "Weapon of Mass Migration" is a term used to describe a hostile government organizing, or threatening to organize, a sudden influx of refugees into another country with the intent of overwhelming its borders or causing p ...
to solidify power or politically destabilize an adversary. The Colombian armed conflict displaced millions of Colombians, and so did the tribal guerrilla warfare (against Soviets) in Afghanistan. The civilian population living in the area might be suspected of having collaborated with the enemy and find itself displaced, as the guerrillas fight for territory.
Growth during the 20th century
The growth of guerrilla warfare in the 20th century was inspired in part by theoretical works on guerrilla warfare, starting with the ''Manual de Guerra de Guerrillas'' by
Matías Ramón Mella written in the 19th century and, more recently, Mao Zedong's ''

groups can provide a focus for popular discontent against a sitting regime, and thereby lead a general
insurrection. Although the original approach was to mobilize and launch attacks from rural areas, many ''foco'' ideas were adapted into
urban guerrilla warfare movements.
Comparison of guerrilla warfare and terrorism
There is no commonly accepted
definition of "terrorism", and the term is frequently used as political propaganda by

s (most often by governments in power) to denounce opponents whose status as
terrorists is disputed.
Contrary to some terrorist groups, guerrillas usually work in open positions as armed units, try to hold and seize land, do not refrain from fighting enemy military force in battle and usually apply pressure to control or dominate territory and population, or deny that control to the enemy. While the primary concern of guerrillas is the enemy's active military units, terrorists largely are concerned with non-military agents and target mostly civilians. Guerrilla forces principally fight in accordance with the law of war (''jus in bello''). In this sense, they respect the rights of innocent civilians by refraining from targeting them.
