This article explores where the people fit in to British history and whether there was such a thing as British public opinion in the seventeenth century. It argues that given the nature of the Stuart multiple monarchy, and the way the power structures of that monarchy impinged upon Ireland, Scotland, and England, the Stuarts' political authority was at times publicly negotiated on a Britannic level. People across Britain were engaged with British affairs: there was public opinion about British politics, in other words, albeit not British public opinion, since the people were bitterly divided at this time. However, because the crisis that brought down Charles I had been a three-kingdoms crisis, which in turn had helped spark the growth of a more sophisticated British news culture, the Restoration monarchy became increasingly sensitive to the need to try to keep public opinion across the Britannic archipelago on its side. In response to the challenge of the Whigs during the Exclusion Crisis, Charles II and his Tory allies sought to rally public support across England, Scotland, and Ireland and thus to represent “British public opinion” as being in favor of the hereditary succession. It was a representation, however, that remained contested.
