What changes did the Boston tragedy force the British authorities to make?

The Boston tragedy aroused greater indignation among the people of North America, and there was a wave of resistance that threatened to erupt into revolution. In order to ease the conflict and relieve the crisis of colonial rule, the British authorities were forced to make concessions by announcing the abolition of all commodity taxes. However, in order to maintain the dignity of the sovereign state and to show that Britain had the right to impose taxes on the colonies, the daily tax on tea (3 pence per pound of tea) was retained. Thus, in the eyes of the North American people, the tea tax became a symbol of tyranny, and people all over the world launched a non-tea drinking movement to resist it. 1773, a night in December, a group of Bostonians disguised as Indians on the East India Company's tea ship, dumped more than 300 boxes of tea worth 150,000 pounds into the sea. This incident greatly boosted the morale of the North American people in their struggle and, at the same time, y angered the British king and his government.

In this way, on the one hand, the British tyranny, on the other hand, the American nation against the British tyranny, a stormy revolution has been inevitable.
