Final answer:
Colonial anger was ignited by British taxes, such as the Sugar and Stamp Acts, due to taxation without representation, and intensified with the Quartering Act requiring colonists to house and feed British soldiers.
Step-by-step explanation:
In the mid-18th century, British attempts to assert greater control over the American colonies with taxes for defense purposes led to significant unrest.
The imposition of the Sugar Act and Stamp Act sparked colonial outrage due to the notion of taxation without representation.
Furthermore, the Quartering Act exacerbated tensions by mandating colonists to provide housing and sustenance to British soldiers, a costly burden that fueled the burgeoning resistance against British rule.
