context_page_description: Boston is the capital and most populous city of the Commonwealth of Massachusetts in the United States, and the 21st most populous city in the United States. The city proper covers 49 square miles with an estimated population of 692,600 in 2019, also making it the most populous city in New England, and is the seat of Suffolk County. The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area home to a census-estimated 4.8 million people in 2016 and ranking as the tenth-largest such area in the country. As a combined statistical area, this wider commuting region is home to some 8.2 million people, making it the sixth most populous in the United States.
  Boston is one of the oldest municipalities in the United States, founded on the Shawmut Peninsula in 1630 by Puritan settlers from the English town of the same name. It was the scene of several key events of the American Revolution, such as the Boston Massacre, the Boston Tea Party, the Battle of Bunker Hill, and the Siege of Boston.
context_section_description: Many of the crucial events of the American Revolution occurred in or near Boston. Boston's penchant for mob action along with the colonists' growing distrust in Britain fostered a revolutionary spirit in the city. When the British government passed the Stamp Act in 1765, a Boston mob ravaged the homes of Andrew Oliver, the official tasked with enforcing the Act, and Thomas Hutchinson, then the Lieutenant Governor of Massachusetts. The British sent two regiments to Boston in 1768 in an attempt to quell the angry colonists. This did not sit well with the colonists. In 1770, during the Boston Massacre, the army killed several people in response to a mob in Boston. The colonists compelled the British to withdraw their troops. The event was widely publicized and fueled a revolutionary movement in America.
  In 1773, Britain passed the Tea Act. Many of the colonists saw the act as an attempt to force them to accept the taxes established by the Townshend Acts. The act prompted the Boston Tea Party, where a group of rebels threw an entire shipment of tea sent by the British East India Company into Boston Harbor. The Boston Tea Party was a key event leading up to the revolution, as the British government responded furiously with the Intolerable Acts, demanding compensation for the lost tea from the rebels. This angered the colonists further and led to the American Revolutionary War. The war began in the area surrounding Boston with the Battles of Lexington and Concord.
  Boston itself was besieged for almost a year during the Siege of Boston, which began on April 19, 1775. The New England militia impeded the movement of the British Army. William Howe, 5th Viscount Howe, then the commander-in-chief of the British forces in North America, led the British army in the siege. On June 17, the British captured the Charlestown peninsula in Boston, during the Battle of Bunker Hill. The British army outnumbered the militia stationed there, but it was a Pyrrhic victory for the British because their army suffered devastating casualties. It was also a testament to the power and courage of the militia, as their stubborn defending made it difficult for the British to capture Charlestown without losing many troops.
  Several weeks later, George Washington took over the militia after the Continental Congress established the Continental Army to unify the revolutionary effort. Both sides faced difficulties and supply shortages in the siege, and the fighting was limited to small-scale raids and skirmishes. On March 4, 1776, Washington commanded his army to fortify Dorchester Heights, an area of Boston. The army placed cannons there to repel a British invasion against their stake in Boston. Washington was confident the army could resist a small-scale invasion with their fortifications. Howe planned an invasion into Boston, but bad weather delayed their advance. Howe decided to withdraw, because the storm gave Washington's army more time to improve their fortifications. British troops left Boston on March 17, which solidified the revolutionaries' control of the city.
