This article explains millenarism as a cultural response to a range of soci
al, economic, and ecological changes that occurred during the past few cent
uries in Oksapmin society. The assumption is that Oksapmin cosmology has al
ways been dynamic and self-innovating toward both endogenous and exogenous
factors of change, tending to integrate emergent elements by modifying its
inner: structure and outer practice. The following analysis focuses on four
main examples of radical transformations due to exogenous causes. All the
changes discussed herein were originated, directly or indirectly, from cont
act with the European world (here defined as white-skinned individuals who
came from the "Western" world in a broader sense) under the form of physica
l persons or material and ideological items. This does not mean that Oksapm
in society has found Vectors of change only in its confrontation with the W
estern world. The choice to analyze the interaction between this indigenous
culture and different manifestations of European culture has been made acc
ording to the anthropologist's ethnographic focus.
