Subsequent English governments continued in their efforts to tax certain goods, passing acts regulating the trade of wool, hats, and molasses. The Molasses Act of 1733 was particularly egregious to the colonists, as a significant part of colonial trade relied on molasses. The taxes severely damaged the New England economy and resulted in a surge of smuggling, bribery, and intimidation of customs officials. Colonial wars fought in America were also a source of considerable tension. The British captured the fortress of Louisbourg during King George's War but then ceded it back to France in 1748. New England colonists resented their losses of lives, as well as the effort and expenditure involved in subduing the fortress, only to have it returned to their erstwhile enemy.
