The American founders who drafted and signed the Declaration of Independence grounded their case for separating from Great Britain on a philosophy of government derived from the writings of John Locke: especially from Lockean notions of legitimate government vs. illegitimate government, i.e. tyranny.

In his Two Treatises of Government, Locke wrote:

“Political power, then, I take to be a right of making laws with penalties of death, and consequently all less penalties, for the regulating and preserving of property, and of employing the force of the community, in the execution of such laws, and in the defence of the common-wealth from foreign injury; and all this only for the public good.”

Here, Locke defined “political power” as power within right, i.e., legitimate government.
