Tumbes is a city in northwestern Peru, on the banks of the Tumbes River. It is the capital of the Tumbes Region, as well as of Tumbes Province and Tumbes District. Located near the border with Ecuador, Tumbes has 94,702 inhabitants. It is served by the Cap. FAP. Pedro Canga Rodriguez Airport. Tumbes has its origins back in pre-Inca times when it was inhabited by a cultural group of natives called Tumpis. At its peak, its population is estimated to have reached 178,000. After 1400, Inca Pachacuti ruled over Tumbes and the territory became an important political stronghold during the Inca Empire. Later Inca emperor Huayna Capac expanded Tumbes by ordering the construction of roads, houses and palaces.
