Final answer:
The Committees of Correspondence were formed by colonists primarily through the action of writing letters to officials, initiated by Samuel Adams via the Massachusetts Circular. These committees were instrumental in unifying the colonies against British policies and in organizing resistance, such as the boycotts against the Tea Act and the response to the Intolerable Acts, which led up to the Revolutionary War.
Step-by-step explanation:
The form of political participation by colonists that led to the development of the Committees of Correspondence was writing letters to officials. Initially, in Massachusetts in 1768, Samuel Adams authored the Massachusetts Circular, a letter that encouraged colonial resistance to British policies by boycotting British goods. This form of communication and coordination soon evolved into the establishment of the Committees of Correspondence, which aimed to share ideas and information across the colonies. With Samuel Adams as a leading figure, and through letters and documents distributed among the colonies, the Committees became pivotal in organizing and unifying colonial opposition, leading to acts of protest such as boycotts and, ultimately, setting the stage for revolution.
The Committees of Correspondence played a significant role in the revolution against British control. They were key in coordinating the resistance to the Tea Act, enabling the colonies to prevent British tea-carrying ships from unloading their cargo as a means of protest. Their activity intensified following the passage of the Intolerable Acts, as they spread warnings and coordinated colonial responses that culminated in the convening of the First Continental Congress. This gathering was in direct response to the Intolerable Acts, drafting a list of grievances and a statement of colonists' rights. As tension with Britain escalated, these Committees facilitated the communication necessary for revolution and were integral to the formation of a new American government.
