The radical Whigs ideology "arose from a series of political upheavals in 17th-century England: the English Civil War, the exclusion crisis of 1679–81, and the Glorious Revolution of 1688.
Broadly speaking, this Whig theory described two sorts of threats to political freedom: a general moral decay which would invite the intrusion of evil and despotic rulers, and the encroachment of executive authority upon the legislature, the attempt that power always made to subdue the liberty protected by mixed government.
[2] The 18th-century Whigs, or commonwealthmen, in particular John Trenchard, Thomas Gordon, and Benjamin Hoadly, "praised the mixed constitution of monarchy, aristocracy, and democracy, and they attributed English liberty to it; and like Locke they postulated a state of nature from which rights arose which the civil polity, created by mutual consent, guaranteed; they argued that a contract formed government and that sovereignty resided in the people.
"Radical Whig perceptions of politics attracted widespread support in America because they revived the traditional concerns of a Protestant culture that had always verged on Puritanism.
An overbearing executive, and the threat of corruption through idle, useless officials, or placemen, had figured prominently in their explanations of their exile in America."
