Final answer:
Colonies communicated about British threats through committees of Correspondence, which were created in Boston and spread to other colonies. They fostered cooperation and provided an alternative to royal governments for information, playing a crucial role before the American Revolution, especially in response to the Intolerable Acts and the Tea Act.
Step-by-step explanation:
Colonies communicated to one another about British threats through committees of Correspondence. These committees played a crucial role in the lead-up to the American Revolution. They facilitated the exchange of ideas and coordination amongst the colonies, and were effective in stirring up resentment against British rule. Established in Boston by Samuel Adams, these committees quickly spread to other colonies, providing a network for sharing information and igniting inter-colony cooperation.
Samuel Adams, along with notable figures like Joseph Warren and James Otis, re-established the Boston Committee of Correspondence as a means to address fears of British overreach. The committees acted as shadow governments and began to supplant royal governments as authorities on public information. After the passage of the Intolerable Acts in 1774, these committees, in cooperation with the Sons of Liberty, warned colonists about the detrimental effects on their liberties. The Intolerable Acts essentially shut down colonial government under the Massachusetts Government Act, spurring more coordinated actions against British policies.
These Committees of Correspondence played pivotal roles during the rebellion against the Tea Act of 1773 and throughout the escalating tensions that led to the Revolution. They exemplify the interconnectedness and revolutionary fervor that eventually fueled the fight for American independence from Britain.
