Guerrilla Warfare as Historical Norm

The Category Error in Military History

Military history as a discipline has a selection bias: it studies the battles that generated decisive outcomes, produced famous commanders, and got written about. Thermopylae, Cannae, Austerlitz, Gettysburg — these are the canonical events. What gets systematically understudied is the grinding, unglamorous, legally ambiguous violence that surrounded these set-pieces: the partisans raiding supply lines, the tribesmen ambushing patrols, the villagers providing or denying shelter. The category "irregular warfare" is itself the product of this bias — defining the exception (conventional battle) as the norm and the actual statistical majority (irregular war) as the deviation.

Boot's first major historical lesson inverts this: guerrilla warfare is not the irregular exception to normal warfare; it is the statistical norm, and conventional interstate warfare is the exception. Of approximately 5,000 years of recorded conflict, formal armies meeting in pitched battle constitute a small and historically recent minority of total warfare events. The ambush, the raid, the low-intensity persistent harassment — these are what war actually looked like for most of human history.1

What the Numbers Say

The 443-insurgency database is Boot's most concrete quantitative contribution, but the historical claim is broader than the database. The database covers only 1775–2013 — a period specifically selected because data quality improves. The qualitative historical argument covers the full 5,000 years.

Boot's claim: every major empire, in every era, spent more resources suppressing irregular opponents than fighting conventional adversaries. The Roman Empire spent centuries managing Germanic tribes, Parthian cavalry raiders, Jewish rebels, and Berber mountain fighters. The British Empire in its 19th-century peak was simultaneously managing irregular warfare in Afghanistan, Sudan, the Northwest Frontier, southern Africa, and multiple colonial theaters. The United States in the 20th century has fought more guerrilla wars than conventional ones by raw count.1

The implication: if you want to understand how states actually use military force across history, the great conventional battles are misleading case studies. The Peloponnesian War, the Roman suppression of Judea, the Mongol conquests — each generated far more irregular warfare, attrition, and unglamorous grinding than the decisive engagements that get named.

The Mechanistic Explanation: Why Guerrilla Is the Default

The reason irregular warfare is the statistical norm is structural, not cultural. Guerrilla tactics are the rational response of any actor who cannot win a conventional engagement:

  1. Power asymmetry creates the demand: As long as there are actors with less military capacity than their opponents — which describes almost every conflict — there will be demand for tactics that circumvent conventional superiority.

  2. The supply is always available: Guerrilla tactics require no specialized equipment, no standing army, no logistical infrastructure. They can be improvised from human communities. Any terrain that can conceal fighters can host guerrilla warfare.

  3. States prefer conventional war but rarely face it: States prefer the decisive set-piece because it allows concentration of their organizational advantage (logistics, firepower, command structure). But states fight other states only when other resolution mechanisms fail — which is rarer than states fighting non-state actors, bandits, rebels, tribes, or other irregular opponents.

  4. Non-state actors have no alternative: A tribe, a revolutionary movement, a criminal syndicate, a religious militia — none of these can build a conventional army from scratch in the short term. Guerrilla warfare is available immediately; conventional capability takes years to build.1

The Pre-Modern Evidence

Boot walks through the ancient and medieval evidence systematically:

  • Scythian warfare: The Scythians defeated Darius the Great's massive Persian invasion (513 BCE) through pure evasion — refusing battle, scorching the earth, drawing the Persian army deeper until it was too exhausted and hungry to continue. No guerrilla cells, no insurgency cells — just the tribal logic of mobility defeating settled-state conventionalism.
  • Maccabean revolt: Judas Maccabeus (167 BCE) used classic guerrilla hit-and-run against Seleucid regulars in Judean mountain terrain. His successors tried to convert to conventional warfare and were destroyed.
  • Viriathus: Led a 20-year Lusitanian resistance against Rome using pure guerrilla mobility. Roman generals could not bring him to decisive battle; the war ended only when Rome bribed his companions to assassinate him.
  • Germanic tribes: Rome spent 200 years managing the Rhine-Danube frontier through what amounted to counterinsurgency — fortifications, surveillance, tribal co-option, punishment expeditions. Conventional engagement was the exception; persistent irregular management was the norm.1

The Implication for How Military History Should Be Studied

If Boot's ubiquity thesis is correct, the conventional curriculum of military history — Thucydides, Clausewitz, Jomini, the great captains — is studying the exception and ignoring the rule. Clausewitz was writing about Napoleonic warfare: nation-states with professional armies fighting decisive pitched campaigns. The doctrine he produced is probably not the most relevant doctrine for most of what armies actually do.

The intellectual corollary: political science and international relations theory, built largely on state-to-state power analysis, has the same bias. The Westphalian state system assumes states as the primary actors; the historical reality is that non-state armed groups have been military actors across every era, and their logic of action is fundamentally different from state military logic.

Tensions

Ubiquity ≠ effectiveness: Boot establishes that irregular warfare is the historical norm. He also establishes (via the 25% success rate) that it usually fails. These are compatible: the default response of weaker parties doesn't necessarily work. But the combination should generate more caution about the "guerrilla as last resort of the heroic oppressed" narrative. Most guerrillas failed. The ones who succeeded are historically celebrated; the majority who were suppressed are forgotten.

Clausewitz's validity range: Boot implies Clausewitz is incomplete, not wrong. Clausewitz's "remarkable trinity" (passion, chance, reason) actually does accommodate irregular warfare — Clausewitz wrote about Volkskrieg (people's war) in Book 6. The critics of Clausewitz often underread him. The real tension is whether the state-centric framework Clausewitz inherited can be extended to non-state actors.

Cross-Domain Handshakes

Polymathic Operating System (Cross-Domain): Polymathic Operating System — Boot's ubiquity thesis is itself a case study in how a field's dominant framework can systematically mislead. The conventional-war bias in military history is an example of what D10 (Archetypal Thinking) would call a "master narrative" that shapes what gets studied and what gets ignored. The polymathic move: look at what the field systematically omits, and that's where the real patterns live. Boot did this with military history; it's a method applicable to any domain.

Shadow Governance Infrastructure (History): Shadow Governance Infrastructure — the NSDAP built a "state within a state" before seizing power. This is a form of irregular political warfare — acquiring the capacity for governance through non-state means before the conventional political transition. The structural parallel to guerrilla ubiquity: just as guerrilla warfare is the default military tactic of the weak, shadow governance is the default political tactic of movements that cannot yet seize the state directly. Both are the irregular approach to an objective the conventional approach cannot yet reach.

The Live Edge

The Sharpest Implication If conventional interstate warfare is the exception and irregular warfare the norm, then military education, military investment, and military doctrine that optimizes for conventional war is systematically preparing for the unlikely case. The United States' investment in aircraft carriers, precision-guided munitions, and combined-arms mechanized warfare produced the world's best force for fighting the Soviet Union — an adversary that no longer exists. The adversaries that have actually challenged U.S. military force since 1945 have been guerrilla insurgencies, almost all of which the United States has either lost or abandoned. The misallocation is not accidental — it follows from the conventional-war bias Boot identifies. Fixing it requires not better weapons but a different theory of what war actually is.

Generative Questions

  • Boot shows guerrilla warfare is the statistical norm. But he also shows it usually fails. Does this combination mean the historical "winners" in military history are mostly states that learned to suppress irregular warfare efficiently — not states that developed the most powerful conventional militaries? Is counterinsurgency competence the real determinant of historical durability for empires and states?
