Question

how did the french and Indian war effect the British and ultimately the colonies

Answer 1

The British began to tax the colonists heavily which ended with the  colonists resenting.

Answer 2

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.
