Final answer:
The Coercive Acts of 1774, including the closure of the port of Boston, had significant effects on the colonies. They sparked opposition and resistance from the colonies, leading to the convening of the First Continental Congress and demands for repeal. The acts also escalated tensions, ultimately leading to the American Revolution.
Step-by-step explanation:
The effects of Parliament passing the Coercive (Intolerable) Acts of 1774, closing the port of Boston, led to various consequences in the American colonies. One of the consequences was the convening of the First Continental Congress in September and October 1774, where delegates demanded that Britain repeal the acts, but Britain refused. This demonstrated the growing opposition and resistance of the colonies against British rule. Another consequence was the escalation of tensions between the colonies and Britain, ultimately leading to the outbreak of the American Revolution. The closing of the port of Boston was seen as a direct attack on the colonies' economy and autonomy, which further galvanized colonists to fight for their independence.
