Why did Jonathan Swift become dissatisfied with the Whig Party?

Although Jonathan Swift was a Whig by birth, education, and political principle, he became increasingly dissatisfied with the party due to his passionate loyalty to the Anglican Church.12

Swift grew apprehensive regarding the Whig administration's growing determination to yield ground to Nonconformists—English Protestants who did not conform to the practices or doctrines of the Church of England. While the Whigs advocated for religious tolerance, Swift’s commitment to the established church made him uneasy with policies that threatened its position.12

Additionally, Swift frequently mocked "free thinkers," or intellectual skeptics who questioned Anglican orthodoxy, further distancing him from the secular or liberal tendencies within the Whig sphere. These tensions eventually led him to align with the Tories, who adopted a more protective attitude toward the Church of England, though he maintained his original convictions regarding the nature of government and rejected the Tory doctrine of the divine right of kings.12
