Major disruptions and challenges to local ecclesiastical and other arrangements in Jersey and Guernsey in the late 1610s have been seen as part of a wider initiative to bring order and system to the churches and realms over which James VI and I held sway. This article explores the full range of these developments, and their local context, to understand the degree to which central and local initiative interacted. This allows for consideration of the coherence of the sequence of events, and their development in narratives which became part of the wider interplay between territories of the English crown, both at the time and in the following two decades, as experienced and constructed from the perspectives of Presbyterian and Laudian controversialists. The evidence advanced suggests both the extent of potential disruption, and the degree to which it was locally driven and only later integrated into narratives of centrally-directed unification.
