In 1773 the British government granted the politically powerful East India Company a monopoly on the export of tea from Britain, eliminating a lucrative form of trade for colonial merchants?

Boston Tea Tax and the Boston Tea Party granted the politically powerful East India Company a monopoly on the export of tea from Britain.

Explanation:

In 1770, Tea was particularly considered as an important commodity. "Boston Tea Party" was a political protest that was started on December 16, 1773 by American against the taxation on tea laid by Britain government.

Britain formulated Boston Tea Tax and decided to make East India Company a monopoly on tea export. This made American frustrated and angry. The colonial merchants were banned from trading of tea. British government unfairly taxed American colonists during French and Indian War.
