The Tea Party was the culmination of a resistance movement throughout British America against the Tea Act, which had been passed by the British Parliament in 1773. Colonists objected to the Tea Act because they believed that it violated their rights as Englishmen to "no taxation without representation", that is, to be taxed only by their own elected representatives and not by a British parliament in which they were not represented. In addition, the well-connected East India Company had been granted competitive advantages over colonial tea importers, who resented the move and feared additional infringement on their business. Protesters had successfully prevented the unloading of tea in three other colonies, but in Boston, embattled Royal Governor Thomas Hutchinson refused to allow the tea to be returned to Britain.
