The Revolutionary War was started in Lexington & concord in 1775.But what got the colonist mad was farther back in 1763 what the Proclamation of 1763 came around.they had been having wars and there had been a lot of killing, because king george wanted everything taxed.So the colonist found a way around that they said,”lets boycott!” So that’s how it started.But I think it started with the war of Lexington & concord.And the Boston tea party or Boston massacre.It got the king upset about the complaining of the colonists about all taxes.So that’s how the revolutionary war started.
