In 1765 Parliament passed the Stamp Act. According to many historians, this was the major cause of the American Revolution, however, the reason that Parliament passed the act was because the French and Indian War had left a huge national debt. It only seemed right to Parliament that the American colonists, whose protection the British army provided during the war, share in some of the responsibility in paying back those debts. Therefore, in a very major way, the French and Indian War caused the American Revolution because with out it, the Revolution may never have taken place.
In the novel Soldiers Don't Cry, the Locket Saga Continues (by my creator--Cygnet Brown) My brother-in-law's friend Samuel Matthew Gray (who Peter always called Matthew) was especially angered by the Stamp Act. (Personally I think he was just looking for something to fight about because he loved to pick fights.)
Matthew was one of the original members of the Sons of Liberty, the name of which originated from a speech that Colonel Isaac Barre gave against the Stamp Act in the House of Commons. The Sons of Liberty were secret organizations formed int the provincial towns in order to organize against the Stamp Act and other British legislation they did not feel was in their best interests.
The Stamp Act was the first event that organized the colonists against the British government. Delegates from 9 f the 13 colonies met in New York to formally protest the Stamp Act. The formal protest was heard because on March 18, 1766, Parliament repealed the act. However, the issue wasn't completely taken off the table because the same day Parliament passed the Declaratory Act which gave Parliament the right to make any laws they wished.
Because of the growing unrest in the colonies, British troopers were sent to Boston to quell the growing unrest in the colonies. This did not however quell anything, but simply reinforced to the colonists that the British government was not interested in allowing the colonists in on the decision making process on how British national debts should be paid.
I hope you have enjoyed this background research that was used when writing the novel in which I am the protagonist (sometimes antagonist) in Soldiers Don't Cry, the Locket Saga Continues by Cygnet Brown
