This chapter discusses how newspapers helped to integrate the vast British Atlantic. Reports and editorials appearing in the dozens of “Weekly Mercuries” carried by ships crisscrossing the ocean gave meaning to an emerging, shared understanding of loyalty and loyalism among the ocean's many and varied British inhabitants. This shared understanding of Britishness drew on Protestant subjects' deeply held fears of their nation's long-standing Catholic enemies, France and Spain. The makings of Daniel Fowle's “Body Politic,” however, depended on reliable Atlantic communication networks, a circulatory system capable of carrying news quickly and regularly to all corners of Britain's vast empire. News of national importance was filtered through these more immediate webs of contact, which played a significant role in shaping distinctive local political cultures and identities in places like New York City, Glasgow, Halifax, and Kingston. During the many wars fought against France and Spain in the first half of the eighteenth century, anti-Catholic rhetoric was able to overshadow divisions within the empire, providing a language of national unity that was so intentionally broad as to appeal to the nation's diverse inhabitants. But in the absence of these wars and these enemies, as was the case for much of the 1760s and 1770s, subjects in these communities struggled to understand what exactly united them as Britons.
