Salutary Neglect
From Conservapedia
Salutary neglect was the period in the American colonies before the French and Indian War in which British enforcement of laws in the colonies was lax.[1][2] The period is generally recognized from 1721 until 1763 after the Seven Years' War, when the 1763 Sugar Act, the 1764 Currency Act, and 1765 Stamp Act were passed.
The name of the policy period was unofficially named, deriving from a later speech given by Edmund Burke.
