Boston is the capital city and most populous municipality of the Commonwealth of Massachusetts in the United States. It is also the seat of Suffolk County, although the county government was disbanded on July 1, 1999. The city proper covers 48 square miles (124 km2) with an estimated population of 673,184 in 2016, making it the largest city in the New England region of the northeastern United States.
The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area (MSA) 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(CSA), this wider commuting region is home to some 8.2 million people, making it the sixth-largest in the United States.
Boston is one of the oldest cities in the United States, founded on the Shawmut Peninsula in 1630 by Puritan settlers from England. 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. Upon U.S. independence from Great Britain, it continued to be an important port and manufacturing hub as well as a center for education and culture. The city has expanded beyond the original peninsula through land reclamation and municipal annexation. Its rich history attracts many tourists, with Faneuil Hall alone drawing more than 20 million visitors per year. Boston’s many firsts include the United States’ first public school (Boston Latin School, 1635), first subway system (Tremont Street Subway, 1897), and first public park (Boston Common, 1634).
