The historiography of English republicanism is dominated by the concept of classical republicanism. Its greatest shortcoming has been neglect of that subject's religious dimension. The consequent need is not simply to recover the radical protestant republican religious agenda. It is to explain why, when classical republicanism came to England, it did so in the moral service of a religious revolution. One context for the answer lay in Christian humanism. Another was the reformation, both magisterial and radical. Both informed the practical identity of the republican experiment as an attempted reformation of manners. So did the rational Greek moral philosophy, as indebted to Plato as to Aristotle, common to certain humanist and Christian political languages. In addition many of the themes of republican writing reflect the struggle by a traditional society to respond to unsettling forces, not only of political and religious, but also social and economic, change. Drawing upon all of these contexts, republican writers attempted to oppose not only private interest politics, embodied by monarchy or tyranny, on behalf of the public interested virtues of a self-governing civic community. This was part of a more general critique of private interest society; a republican attempt, from pride, greed, poverty, and inequality, to go beyond the word ‘commonwealth’ and reconstitute what Milton called ‘the solid thing’.
