Why was the colonists mad at the suger act?

Colonists were upset with the Sugar Act of 1764 because it imposed taxes on sugar and molasses imported into the colonies, which they felt was an unfair economic burden. They believed that such taxes, enacted without their consent, violated their rights as British subjects, particularly the principle of "no taxation without representation." Additionally, the act aimed to strengthen enforcement against smuggling, leading to further resentment toward British control. This growing anger contributed to the larger movement for independence.
