Several times while we were colonists of Great Britain, our merchants organized a boycott of British products because they were unhappy with the British policies. For the most part, these boycotts were successful.
When the Stamp Act was passed, the colonists were upset. The colonists believed the British were violating their rights as British citizens by passing tax laws without the colonists having representatives in Parliament who could speak about and vote on the proposed taxes. Thus, the colonists agreed to boycott British products. The boycott was successful as the British eventually agreed to repeal the taxes from the Stamp Act.
When the Townshend Acts were passed in 1767, the colonists again were unhappy. As a result, another boycott was organized. Additionally, the colonists agreed to make their own products. This could have potentially caused long-term issues for the British merchants. While the Townshend Act taxes were repealed after the Boston Massacre, the boycott was effective in disrupting the sale of products of the British merchants. Thus, the actions of the colonists were helpful and effective in getting unpopular taxes repealed.
