Final answer:
The British ended their policy of salutary neglect to raise funds for colonial defense and maintenance, leading to stricter controls and taxation of the American colonies, which angered colonists due to perceived violations of their rights and expectations of self-governance.
Step-by-step explanation:
The British changed their policy of "salutary neglect" because they needed to raise funds to cover the costs of protecting and maintaining the American colonies after the French and Indian War. This decision to enforce stricter control and taxes was a radical shift from their previous approach of allowing the colonies to operate with significant autonomy. The colonists were angered by this change as it contradicted their expectations of reward and self-governance after their contribution to the war effort. They felt their rights under the British constitution were being violated, especially with regard to taxation without representation. The end of salutary neglect and the imposition of new taxes without the colonists' consent were perceived as an infringement on their rights and liberties.
Furthermore, the British sought to repay war debts and maintain peace with Native Americans by keeping troops in North America. This required funding, leading to the implementation of new taxes on the colonists and more rigorous enforcement of existing trade regulations. Many colonists felt that these practices violated the protections guaranteed by the English Bill of Rights and were indicative of a government hostile to their interests.
