Answer: The Boston Massacre (March 1770), The Boston Tea Party (December 1773, The Stamp Act (March 1765).
Explanation:
All these events deepened the colonists' dissatisfaction and ultimately influenced the start of the war for independence.
The Boston Massacre is one of those factors. Namely, in Boston, a simple quarrel between a man who cleans shoes and a British soldier resulted in a murder. When a British soldier attacked a man after an argument with a colonist, people intervened to protect the man. After the commotion broke out, British soldiers opened fire on a mass of colonists. The result was several dead and wounded. The colonial newspapers of that period waged a fierce campaign against the British, which caused great anger among the people.
The Boston Tea Party is an event in which Britain decided to introduce its company's monopoly on the sale of tea. The colonists did not like it, so one night, they threw several tons of British tea into the sea. The British decided to punish the perpetrators, which the colonists did not like.
The Stamp Act is another effort in a series of authorities from England to get rich at the colonists' expense. Namely, the parliament passed a law in which stamps must be used or printed exclusively on paper produced in London. It is an attempt to introduce a monopoly.
