What was the challenge faced by the Divine Right theory during the
seventeenth century?

Divine right of kings, in European history, a political doctrine in defense of monarchical absolutism, which asserted that kings derived their authority from God and could not therefore be held accountable for their actions by any earthly authority such as a parliament. Originating in Europe, the divine-right theory can be traced to the medieval conception of God’s award of temporal power to the political ruler, paralleling the award of spiritual power to the church. By the 16th and 17th centuries, however, the new national monarchs were asserting their authority in matters of both church and state. King James I of England (reigned 1603–25) was the foremost exponent of the divine right of kings, but the doctrine virtually disappeared from English politics after the Glorious Revolution (1688–89). In the late 17th and 18th centuries, kings such as Louis XIV (1643–1715) of France continued to profit from the divine-right theory, even though many of them no longer had any truly religious belief in it. The American Revolution (1775–83), the French Revolution (1789), and the Napoleonic Wars deprived the doctrine of most of its remaining credibility.
