a couple of years ago, i wrote a fairly lengthy report on the canadian indian act that required going back and really understanding the historical roots of that piece of legislation, which had me research the royal proclamation of 1763, as well as the origins of the canadian constitution, which was written in direct response to the american civil war. the framers of the canadian constitution were laser focused on denying any concept of states rights, as they identified it as the cause of the civil war. but, the role of american farmers (and their rejection of the 1763 proclamation) was also a substantive factor underlying the motives of the british state in the decades of policy that led up to the erection of the indian act by the canadian state, in 1876. so, i remember doing a lot of reading on american farmers, and particularly their relationship to indigenous groups, which in that period was pretty horrific. i think it is plausible that i may have picked up knowledge on the populist uprisings when researching american farmers in that period, in the context of understanding their relationship to the indigenous population, in the framework of british-canadian constitutional law. as such, i wasn't paying particular attention to erecting close reference notes.

but, there may be hints to useful reference material in the footnotes of the following essay:
