This chapter takes a historical approach to the Cenepa war, seen from the classical theory of Jomini's war.Relevant methods are used from the historical context and applied in research from a chronology, geography and ethnography perspective.Through a review of the literature on these events, observing that not many studies have been carried out on this historical episode beyond the chronicles and approaches made by Peruvian and Ecuadorian academics and journalists, the particularities of the events that occurred as part of the construction of the memory of the Latin American context are exalted.
