A. SUGAR AND MOLASSES ACT

Resistance by the colonists was immediate and intense. In a speech before the Virginia House of Burgesses, Patrick Henry made such stirring statements that many conservatives began to echo "Treason." When the hall quieted down, Henry added, "If this be treason, make the most of it." Patrick Henry's resolutions to oppose the laws were passed and put into effect by the other colonies. One of the main resolutions required the boycotting of goods imported from England. Trade with England dropped as much as 25 percent in one year. That got the attention of the English government, as merchants in the mother country were hit by the loss of trade.

With so many complaints, Parliament had no other choice but to repeal the Stamp Act and reduce the sugar tax. The Stamp Act had been in force for only four and a half months.
