Description
Repertoires are often shared between social actors; as one group (organization, movement, etc.) finds a certain tool or action successful, in time, it is likely to spread to others. While the term is used most often in the social movement theory context, it can be applied to any political actors. Repertoires of contention also existed before the birth of the modern social movement (a period most scholars identify as the late 18th to early 19th century). == Historical development ==
Historical development
Much attention has been given to substantial and lasting changes in the repertoire of collective action over time, though these changes tend to take hold unevenly and in given regions. Tilly notes that, "Some time in the nineteenth century, the people of most western countries shed the collective-action repertoire they had been using for two centuries or so, and adopted the repertoire they still use today." Related arguments suggest the increasing centrality of climate-based struggles within the repertoire. ==References==
