Bacon's Rebellion in 1676 was an early instance of colonial defiance of authority. The Navigation Acts and other laws enforced by the Board of Trade and writs of assistance led to growing tensions between Britain and its colonies over taxation and trade. The French and Indian War resulted in new lands for Britain but also the Proclamation of 1763, angering colonists. A series of taxation acts, along with events like the Boston Massacre and Tea Party, prompted the First and Second Continental Congresses and battles at Lexington, Concord, and Bunker Hill, moving the colonies towards open conflict and a declaration of independence.
