The modern liberal state arose as part of a rebellion against the entrenched hierarchies of rank, power, and privilege that had characterized the feudal order of European society. Under that order, a person's prospects in life were determined almost entirely by his status at birth. The individual lacked the liberty to change his social and economic ranking and was rendered dependent on the will of those in higher-ranking positions. It was against this inclusive, closed, and ascriptive system of inequality and dependence that the proponents of the liberal state fought.

Modern liberalism developed out of the strife of post-Reformation religious warfare. Among liberalism's central ideas were those of the individual's right of religious liberty and the separate jurisdictions of secular and religious authority. In societies that accepted these ideas and put them into institutional practice, levels of systemic religious violence were dramatically diminished. Moreover, the liberal principles that helped to build and sustain civil peace could make a strong claim to providing a just framework for addressing religious differences. Yet important normative questions have remained about the policies a liberal state should adopt toward religion.
