The French and Indian war marked a major turning point in American relations with Great Britain, with changes such as increased British control and anti-British sentiment in the colonies, but also continuities such as a loyalty to Britain that remained largely untouched by the war.
This war was a turning point, because after the war, Britain made many laws and taxed the colonies harshly for the cost of war, which they blamed the colonies for, and this sparked a revolutionary spark that lead to the The Revolutionary War. Source: Hamilton The Musical lolol
