The starting point for our considerations on the problem of the partisan is the guerrilla war that the Spanish people fought against the army of a foreign conqueror from 1808 to 1813. In this war, for the first time, the people confronted a modern, well-organized regular army that emerged from the experiences of the French Revolution. This opened up new dimensions of warfare, developed new concepts of military strategy, and gave rise to a new doctrine of war and politics. The partisan fights irregularly. Throughout all of human history and its many wars and struggles, there have been rules of war and combat, and consequently, also violations and disregard for those rules. It should be noted, however, that for a theory of the partisan as a whole, the strength and significance of its irregularity depend on the strength and significance of what it engages in.
