The Tea Act of 1773 angered colonists primarily because it favored a British company (the East India Company) over colonial merchants. The act allowed the company to sell tea directly to the colonies, undercutting local merchants and removing the tax advantages that colonial tea sellers had previously enjoyed. This perceived favoritism and threat to local businesses contributed to the growing unrest that ultimately led to events such as the Boston Tea Party.
