Query: Who's liberal political ideas influenced the Whigs?
Context: As well as championing constitutional monarchy with strict limits on the monarch's power, the Whigs adamantly opposed a Catholic king as a threat to liberty, and believed in extending toleration to nonconformist Protestants, or dissenters. A major influence on the Whigs were the liberal political ideas of John Locke, and the concepts of universal rights employed by Locke and Algernon Sidney.
