How did salutary neglect to promote self-government in the colonies?

Salutary neglect was an undocumented, 'though long-standing, the British policy of avoiding strict enforcement of parliamentary laws, meant to keep the American colonies obedient to Great Britain. Prime Minister Robert Walpole stated that "If no restrictions were placed on the colonies, they would flourish"[citation needed]. This policy, which lasted from about 1607 to 1763, allowed the enforcement of trade relations laws to be lenient. Walpole did not believe in enforcing the Navigation Acts, established under Oliver Cromwell and Charles II and designed to force the colonists to trade only with England, Scotland and Ireland,which were also under Britain's control. Successive British governments ended this policy through acts such as the Stamp Act and Sugar Act, causing tensions within the colonies.

Salutary neglect occurred in three time periods. From 1607 to 1696, England had no coherent imperial policy. From 1696 to 1763, England (and after 1707 Britain) tried to form a coherent policy (navigation acts) but did not enforce it. Lastly, from 1763 to 1775 Britain began to try to use a coherent policy.

Salutary neglect was a large contributing factor that led to the American Revolutionary War. Since the imperial authority did not assert the power that it had, the colonists were left to govern themselves. These essentially sovereign colonies soon became accustomed to the idea of self-control. The effects of such prolonged isolation eventually resulted in the emergence of a collective identity that considered itself separate from Great Britain.

The turning point from salutary neglect to an attempt enforce British policies was the Seven Years' War (French and Indian War). Great Britain was fighting France for imperial control of the known world (including North America, where the war was started and was losing very badly until Secretary of State William Pitt took charge. To help the war Britain toward the Colonists. These tensions caused England to abandon its policy of salutary neglect, which led directly to the American Revolution.
