Where did the first phase of the american revolution primarily take place?

In 1763 the British Government, reasonably from its point of view, moved to tighten the system of imperial control and to force the colonists to contribute to imperial defense, proposing to station 10,000 soldiers along the American frontiers and to have the Americans pay part of the bill. This imperial defense plan touched off the long controversy about Parliament's right to tax that started with the Stamp and Sugar Acts and ended in December 1773, when a group of Bostonians unceremoniously dumped a cargo of British tea into the city harbor in protest against the latest reminder of the British effort to tax. In this 10-year controversy the several British ministries failed to act either firmly enough to enforce British regulations or wisely enough to develop a more viable form of imperial union, which the colonial leaders, at least until 1776, insisted that they sought. In response to the Boston Tea Party, the king and his ministers blindly pushed through Parliament a series of measures collectively known in America as the Intolerable Acts, closing the port of Boston, placing Massachusetts under the military rule of Maj. Gen. Sir Thomas Gage, and otherwise infringing on what the colonists deemed to be their rights and interests.
