During the colonial period and the Revolutionary War, Long Island stood at the center of events that shaped both New York and the emerging United States. From early English settlements in the 1600s to military occupation, divided loyalties, and wartime espionage in the 1700s, the island’s harbors, farms, villages, and strategic location made it a key part of the story. Today, preserved historic districts, local museums, and well-known Revolutionary-era landmarks still connect visitors to that past.

Early Colonial Settlements

  • Southold (1640): One of the earliest English settlements on Long Island, founded by Puritans from New England.
  • Southampton (1640): Established the same year, it remains one of the oldest English towns in New York.
  • Huntington, Brookhaven, and East Hampton: These growing communities developed around farming, trade, and access to coastal waters, including Long Island Sound.
  • Oyster Bay & Hempstead: Important colonial settlements that later figured in regional trade, local politics, and Revolutionary-era activity.

Together, these settlements helped establish Long Island as a region of farms, fisheries, maritime trade, and small villages that would later be drawn into the struggle between Britain and the colonies.

The Revolutionary War on Long Island

The Battle of Long Island (1776)

  • Also known as the Battle of Brooklyn, it was the first major battle after the Declaration of Independence was adopted in 1776.
  • Although the fighting took place mainly in what is now Brooklyn, at the western end of Long Island, the outcome affected the entire island.
  • George Washington’s army was forced to retreat, and the British went on to hold New York City and much of Long Island for most of the war.

British Occupation

  • From 1776 until the war’s closing years, much of Long Island remained under British control.
  • Residents could face requisitions of food, livestock, and shelter, and daily life was often shaped by military needs.
  • Communities were divided among Loyalist, Patriot, and neutral sympathies, creating lasting local tensions and hardships.

The Culper Spy Ring

  • Long Island’s best-known Revolutionary War story is the Culper Spy Ring, one of the most famous intelligence networks of the war.
  • Organized under George Washington, it included Abraham Woodhull of Setauket, known as “Samuel Culper Sr.,” and Robert Townsend of the Oyster Bay area, known as “Samuel Culper Jr.”
  • The network operated through Setauket and other points on Long Island, gathering intelligence on British activity in New York City.
  • Anna Strong is traditionally associated with signaling methods linked to the ring, though some details have become part of local legend over time.
  • The Culper network supplied Washington with valuable information and remains one of the island’s most enduring Revolutionary-era stories.

Legacy of the Colonial & Revolutionary Era

  • Historic Places to Explore: Visitors can explore communities such as Setauket, Huntington, Oyster Bay, Southold, and Southampton, where colonial-era homes, churches, cemeteries, and historic districts help preserve the island’s early story.
  • Museums, Markers & Local History Sites: Historical societies, house museums, memorials, and interpretive markers across Long Island provide context on settlement, wartime occupation, and espionage.
  • Living History & Special Events: Reenactments, lectures, walking tours, and heritage programming are offered in some communities during the year, especially around major anniversaries and seasonal events.
  • Place Names: Many towns, roads, and landmarks still carry names from the colonial period, linking present-day Long Island to its earliest European settlements and Revolutionary-era families.

If you plan to visit historic sites, keep in mind that many are operated by towns, nonprofits, or local historical societies. Hours, tour schedules, and special programming can vary by season, so it is wise to check ahead before making a dedicated trip.
