Answer:
Stamp Act Congress.
Step-by-step explanation:
The colonial group which was formed first is the Stamp Act Congress and it was established on the 7th of October, 1765 in New York city. The Stamp Act Congress is also referred to as the Continental Congress of 1765.
Stamp Act Congress was a meeting which comprised of various elected representatives from the British colonies of North America. The meeting was considered to be the first of its kind and was presided over by the chairman of the Congress, Timothy Ruggles.
The main purpose of the Stamp Act Congress was to create a uniform group protest against the new taxation imposed by the British.
Hence, the American colonist saw the Stamp Act as an internal tax because it required the use of uniquely stamped paper or payment for wills, calendar, diplomas, newspapers, playing cards and other legal documents. Thus, the elected representatives from the British colonies of North America opposed it strongly by devising a protest.
