What were two consequences of the French and Indian War? Include the Proclamation
34kurt

Answer:

1. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American revolution.

2. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims.
