In Achiote, the problem of its founding origins and the behavior of Catholicism captivated us. Our objectives were to approximate its founding origins, given the evident lack of knowledge among its own inhabitants in the 21st century, and to study the behavior of Catholicism from an Italian microhistorical perspective. This study employs a non-experimental design, which led us to

conduct fieldwork with exploratory and/or explanatory aspects, supported by a qualitative approach. The absence of written documentary sources forced us to rely on the tools of oral history, historical anthropology, and Italian microhistory. The results show that this human settlement may have originated around 1922 when the American authorities permitted agricultural activity by granting land-use permits; And that fragmentary remnants of ancient patterns of anti-reformation Catholicism from the 16th and 17th centuries combined with new regulations that made access to the Sacraments more rigorous for parishioners, produced severe ruptures with the forms of religious expression legitimized in the harsh daily life of Achiote. This research gives voice to the stories of Achiote residents who, as social actors, were excluded from history, and whose oral testimonies allowed us to approach the founding origins of the town of Achiote, reconstruct the past state of Catholicism, and examine its behavior.
