British troops occupy Boston

In October 1768, British regulars sent by Lord Hillsborough and authorized by the ministry of Augustus FitzRoy, Duke of Grafton, landed in Boston, Massachusetts, to support customs enforcement and royal authority. The troops came after Massachusetts politicians, Boston merchants, and town leaders resisted the Townshend Acts and circulated the Massachusetts Circular Letter. Redcoats camped in a town already crowded with civilians, and their presence placed imperial military power in the streets around the Custom House, the Town House, and the waterfront.

The occupation deepened the constitutional quarrel over whether Parliament could tax the colonies and use troops to enforce revenue laws against local opposition. Boston leaders such as Samuel Adams treated the arrival of regulars as evidence that ministerial policy threatened the traditional balance between civil authority and military force in an English constitution. Everyday friction over work, housing, and street authority then made Boston a flashpoint, because soldiers and civilians encountered one another constantly in a town already inflamed by arguments over taxation and representation.

The occupation set the stage for the Boston Massacre on March 5, 1770, when the long tension between soldiers and townspeople turned deadly on King Street. It also became part of the indictment later expressed in the Declaration of Independence, which accused George III of quartering armed troops and making the military independent of civil power.
