Boston historical timeline

History

A Puritan settlement that became the place the American Revolution started, then spent two centuries enlarging itself by filling in the sea.

Chronology

c. 5000 BCE — Native people build a fishweir on what is now Boylston Street, one of the oldest in New England and constructed as early as 7,000 years before Europeans reached the western hemisphere. Structural impact: none standing. What you see today: the reason the Back Bay is soft ground — it was tidal flats long before it was streets.
1630 — settlers led by John Winthrop arrive and find the Shawmut Peninsula nearly empty of Native people, most having died of European diseases carried by earlier traders. The first European resident, the Cambridge-educated Anglican cleric William Blaxton, invites the Puritan leader Isaac Johnson across from the failing Charlestown colony. Structural impact: the town founded on a three-hilled peninsula barely connected to the mainland. What you see today: the tangled, ungridded street plan of downtown, which grew rather than being laid out.
30 September 1630 — Isaac Johnson, in one of his last acts before his death, names the settlement Boston after his home town in Lincolnshire, itself named for St Botolph. Structural impact: none. What you see today: the name, and nothing else of Johnson.
1634 and 1635 — Boston Common is established, and Boston Latin School founded. Structural impact: a permanent 50-acre open space at the centre of a city that would otherwise have built on it. What you see today: the oldest public park and the oldest public school in the United States, both still in use.
1770 — five soldiers of the 29th Foot fire into a Boston crowd in what becomes the Boston Massacre, after Britain sent 2,000 troops in 1768 to occupy the town. Structural impact: the occupying troops are withdrawn. What you see today: the marked site outside the Old State House, on a traffic island.
1773 — Bostonians throw an entire East India Company shipment of tea into Boston Harbor in response to the Tea Act. Parliament replies with the Intolerable Acts. Structural impact: none to the town; everything to its politics. What you see today: a harbour whose shoreline has since moved, so the site is no longer at the water.
1775–1776 — the Battles of Lexington and Concord on 19 April 1775 open the Revolutionary War, and the Siege of Boston follows. On 17 June the British take Charlestown at the Battle of Bunker Hill in what proves a pyrrhic victory, and afterwards avoid large-scale engagements. Structural impact: Charlestown burned. What you see today: the Bunker Hill Monument, and a Charlestown rebuilt after the fire.
19th century — the city expands far beyond the original peninsula by filling in land and annexing neighbouring towns, and becomes a literary capital: Emerson, Thoreau, Hawthorne, Margaret Fuller, Longfellow. Structural impact: the Back Bay and much of the modern city are made ground, not natural land. What you see today: the abrupt change from crooked colonial lanes to the ruler-straight grid of Back Bay — the join between what grew and what was engineered.
1852 — the Boston Public Library is founded, the first free library in the United States. Structural impact: a civic institution on a scale then unknown. What you see today: the library in Copley Square, still free and still open.
1897 — the Tremont Street subway opens, the first subway system in the United States. Structural impact: transit moved under a street plan too narrow to widen. What you see today: the Green Line, which still runs through parts of it.

Checked against Wikipedia — Before European colonization the region surrounding present-day Boston was inhabited by the Massachusett people, in 1630 settlers led by John Winthrop arrived and found Shawmut Peninsula nearly empty of Native people as most had died of European diseases borne by earlier settlers and traders, and archaeological excavations have unearthed one of the oldest fishweirs in New England located on Boylston Street which Native people constructed as early as 7,000 years before European arrival in the Western Hemisphere, The first European to live in what would become Boston was a University of Cambridge-educated Anglican cleric named William Blaxton, who was most directly responsible for the foundation of Boston by Puritan colonists in 1630 after inviting one of their leaders, Isaac Johnson, to cross Back Bay from the failing colony of Charlestown and share the peninsula with him, and Isaac Johnson named the new settlement Boston after his hometown of Boston, Lincolnshire in one of his last official acts before his death on 30 September 1630, Boston was founded on Shawmut Peninsula in 1630 by English Puritan settlers who named the city after the market town of Boston, Lincolnshire, England, and during the American Revolution and Revolutionary War was home to the Boston Massacre of 1770, the Boston Tea Party of 1773, the Battle of Bunker Hill of 1775 and the Siege of Boston of 1775 to 1776, Boston expanded significantly beyond the original peninsula by filling in land and annexing neighboring towns, and its many firsts include the nation's first public park, Boston Common of 1634, the first public school, Boston Latin School of 1635, and the first subway system, the Tremont Street subway of 1897, The British government sent 2,000 troops of the 14th Foot and 29th Foot to Boston in 1768 to occupy the city, in 1770 five soldiers of the 29th Foot fired into a Boston mob in what became known as the Boston Massacre which led to the withdrawal of the occupational troops, the Tea Act of May 1773 led to the Boston Tea Party in which Bostonians threw an entire shipment of tea sent from the East India Company into Boston Harbor, and Parliament responded by implementing the Intolerable Acts, The Battles of Lexington and Concord on 19 April 1775 were the first battles of the American Revolutionary War, during the siege of Boston from 19 April 1775 to 17 March 1776 New England-based Patriot militia impeded movement by the British Army, and on 17 June the British captured Charlestown during the Battle of Bunker Hill in what proved to be a pyrrhic victory that led the British to avoid further large-scale engagements, Some consider the Old Corner Bookstore to be the cradle of American literature, the place where Boston's 19th-century writers met and where The Atlantic Monthly was first published, and in 1852 the Boston Public Library was founded as the first free library in the United States, Boston's oceanfront location made it a lively port and the town engaged in shipping and fishing during the colonial era, and Boston was a primary stop on the Caribbean trade route and imported large amounts of molasses which led to the creation of Boston baked beans (September 2026).
