Why might England's trade policies angered colonists enough to dump tea in Boston harbor and eventually start a revolution?

England's trade policies, particularly the Tea Act of 1773, angered colonists because they imposed taxes without representation and granted the British East India Company a monopoly on tea sales, undermining local merchants. These policies were seen as an infringement on their rights and economic freedom, leading to widespread resentment. The Boston Tea Party was a direct protest against these oppressive measures, symbolizing the colonists' refusal to accept unjust taxation and their desire for self-governance, ultimately fueling revolutionary sentiments.
