A conqueror dominates a territory and to happen from time, culture is imposed on the quasi-local population, but this model is not always accurate in its development. The culture shock was followed by the subsequent language change meant the displacement of local languages Catacaos, Colan, Sechura Huancapampa Huayacuntu and Andean pan by language (Quechua) and European (Castilian). Apparently local languages did not show an attitude permeable against loans from other languages that were imposed violently (Quechua – Castilian) have happened otherwise could have survived. Possible stages postulate that happened the extinction of the native languages of Piura. First Stage: Siglo XVI. After the arrival of the Spanish in 1532 local languages are languages circulating among various chiefdoms, where communication between them even though they differ in ecosystems is feasible, thanks to the commercial interaction and in some cases the relationship of origin and occurred with Catacaos and Colan, Ayahuaca and avocado, etc.
The chiefdoms in this first stage maintain their natural languages. Quechua Inca domination imposed cease to speak in the common population, limiting their use to MITM enclaves. Local languages are constituted in "language in" political and cultural resistance. The encomienda as a royal grant was to divide a group of indigenous families to Spanish, which gave him the right to receive the tribute of the Indians and gave the Spanish a duty to protect and ensure religious instruction. In Piura 3557 there were 29 parcels with tax. With the encomienda is disturbed and split the old chiefdoms.
