Whereas Americans had quickly won redress amid the Stamp Act controversy, over the following decade the use of similar, affiliated social movement organizations exacerbated rivalries with Britain and eventually mobilized the War of Independence. First, colonists responded to the hated Townshend Acts of 1767 with boycotting associations that sought to overturn the measure through economic warfare – that only led to partial changes. American rights became a partisan issue with Britain, as colonial patriots increasingly allied with the Wilkes and Liberty movement. The enduring tax on tea and the colonial resistance it inspired in 1774 motivated British passage of the Coercive Acts, that militarized the colonial networks and led them to prepare for war. Committees of Safety and Security seized power in many locales and proved integral in mobilizing the civil war against the British.
