The objective of this article is to perform an analysis of the trajectory of mutualism in the far north and Near north of Chile from 1862 to 1922. It is argued that during this period, mutualism became an associative idea that went beyond the limits of the so-called mutual aid organizations to project itself on various types of collectivities. These started to add a set of additional objectives, being expanded on the growing social fabric in formation, although solidarity was the central essence. This led the organization to commit itself in various aspects which, in addition to social protection, considered enlightenment, recreation, and resistance against capital. From the information generated by the Work Office, its purposes, social composition, association with the State, subsidies and retirement will be analyzed. As well as the schools, conferences and libraries that were held.
