Answer: The first major American opposition to British policy came in 1765 after Parliament passed the Stamp Act, a taxation measure to raise revenues for a standing British army in America. Under the banner of “no taxation without representation,” colonists convened the Stamp Act Congress in October 1765 to vocalize their opposition to the tax. With its enactment on November 1, 1765, most colonists called for a boycott of British goods and some organized attacks on the customhouses and homes of tax collectors. After months of protest, Parliament voted to repeal the Stamp Act in March 1766.
