A striking feature of fifteenth-century historiography is the manner in which accounts of political thought in this period have tended to follow two basically distinct courses. One group of historians has pursued the avenue of humanist political theory, primarily in Florence, running from Coluccio Salutati and Leonardo Bruni at the beginning of the fifteenth century down to Machiavelli at its end, tracing the rise and decline of the republican ideal, or myth, in Florentine politics and from there into the mainstream of Western political theory. Another group has concerned itself with conciliar theory in the Church, pursuing its development through the councils of Pisa, Constance, and Basel to its demise in the early sixteenth century. These historians, too, have connected conciliar thought to the broader course of Europe's political development.
