Answer:
British leaders also felt the need to tighten control over their empire. To be sure, laws regulating imperial trade and navigation had been on the books for generations, but American colonists were notorious for evading these regulations. They were even known to have traded with the French during the recently ended war. From the British point of view, it was only right that American colonists should pay their fair share of the costs for their own defense. If additional revenue could also be realized through stricter control of navigation and trade, so much the better. Thus the British began their attempts to reform the imperial system.
