The area that is now Chatham and surrounding Morris County has been inhabited by the Lenape people for thousands of years before Europeans first arrived.To Lenapehoking and Beyond!, Morris County Historical Society, November 2, 2021. Accessed February 11, 2026. "The Lenape, 'the people,' are thought to have lived in this area for at least 10,000 years before the arrival of the Europeans." During historic times, Europeans began trading with the Native Americans who farmed, fished, and hunted in the area when it was claimed as part of New Netherlands. The community that now is Chatham was first settled by Europeans in 1710 within Morris Township, in what was then the English Province of New Jersey. The community was settled because the site already was on the path of a well-worn Native American trail, the location of an important crossing of the Passaic River, and being close to a gap in the Watchung Mountains. The residents of the English community changed its name from John Day's Bridge to Chatham, New Jersey in 1773.
Chatham's residents were active participants in the American Revolutionary War, which ended in 1783. Chatham Township was formed as a local government in the new state of New Jersey on February 12, 1806, taking its name from this pre-revolutionary village. Initial local government forms were limited while the new state government evolved. The new township governed the village of Chatham that lay within the present-day borough boundaries, along with several other pre-revolutionary, colonial villages and large areas of unsettled lands connecting or adjacent to them. On August 19, 1892, Chatham adopted a new village form of government when it became allowed within townships in the state after the revolution. Shortly thereafter, once it was allowed, the village of Chatham reincorporated for governance as a borough by an act of the New Jersey Legislature on March 1, 1897, returning to complete independence from the surrounding Chatham Township.Snyder, John P.

An early railroad located along the Morris and Essex Lines that had become well established by the start of the Civil War as one of America's first commuter railroads, had a stop at Chatham, which attracted many from nearby Manhattan, 20 miles to the east. It remains a commuter town for residents who work in New York City. Today, Chatham is a pedestrian-friendly community that covers less than , including a central business district and railroad station within approximately from its farthest boundary. The borough is situated in southeastern Morris County bordering both Essex and Union counties along the Passaic River. Northeast of the borough is the upscale Mall at Short Hills located in the Short Hills section of Millburn.

History Indian habitation
Occupied for thousands of years by Native Americans, this land was overseen by clans of the Minsi and Lenni Lenape, who farmed, fished, and hunted upon it. They were organized into a matrilineal, agricultural, and mobile hunting society sustained with fixed, but not permanent, settlements in their clan territories. Villages were established and relocated as the clans farmed new sections of the land when soil fertility lessened and moved among their fishing and hunting grounds.
Early European settlement
In 1498, John Cabot explored this portion of the New World. The area was claimed as a part of the Dutch New Netherland province, where active trading in furs took advantage of the natural pass west, but, the Lenape prevented permanent settlement beyond what is now Jersey City. Although rapid exhaustion of the local beaver population soon turned the Dutch interests much farther north, contention existed between the Dutch and the British over the rights to this land and battles ensued. Passing to the rule of the British as the Province of New Jersey upon the fall of New Amsterdam in 1664, and becoming one of its original thirteen colonies, marks the beginning of permanent European settlements on this land.
The land that would become Chatham was part of the Province of East Jersey; the Indian rights to Chatham were purchased in 1680 from members of the Minsi and Lenni Lenape tribes. They spoke an Algonquian language. They hunted and fished in the area and farmed on the lands of their settlements. The area was well connected with established paths among their settlements, to and from bountiful resources, and to neighboring settlements. Safe passageways through the valleys, marshes, swamps, and mountains of this portion of the Watchung Mountains connected the area that would become Chatham with other settlements in the area. Except for highways built since the 1970s and a shunpike built to avoid tolls on the roads connecting the colonial settlements of Chatham and Bottle Hill, the roads of the area follow those time proven, long trodden trails made by the native tribes. Main Street rises from a shallow crossing of the Passaic River and, after traveling through what became the settlements of Chatham and Bottle Hill (which became Madison), the road follows a westward path that leads to the top of the plateau on which Morristown was founded.
In 1680, the British first purchased this Lenape land upon which John Day made the first European settlement in 1710. He chose to settle upon the western bank of the Fishawack Crossing (of the Passaic River) on the traditional Lenape Minisink Trail. Chatham was in the area delineated as Morris Township by the English. The landing at that location was the best place to ford the river and always had been used by the Lenape on their route to the Hudson River and south from their hunting grounds in what is now Sussex County. That traditional part of the Great Trail would become today’s Route 124, leading to Madison, Morristown, Mendham, and Chester. It became known as Main Street in Chatham.
Establishment
Before long, the village became known as John Day's Bridge because of a bridge he built across the river at the shallow landing. By 1750, the village had a blacksmith shop as well as a flour mill, a grist mill, and a lumber mill.
In 1773, the village was renamed to "Chatham" to honor a member of the British Parliament, William Pitt, the first Earl of Chatham, who was an outspoken advocate of the rights of the colonists in America.Hutchinson, Viola L. The Origin of New Jersey Place Names, New Jersey Public Library Commission, May 1945. Accessed August 28, 2015.Gannett, Henry. The Origin of Certain Place Names in the United States, p. 77.

New Jersey was one of the Thirteen Colonies that revolted against British rule in the American Revolutionary War. The New Jersey Constitution of 1776 was passed on July 2, 1776, two days before the Second Continental Congress declared American Independence from Great Britain. It was an act of the New Jersey Provincial Congress, which made itself into the state legislature. To reassure neutrals, it provided that it would become void if the state of New Jersey reached reconciliation with Great Britain.
The citizens of Chatham were active participants in the Revolutionary War and nearby Morristown became the military center of the revolution. George Washington twice established his winter headquarters in Morristown and revolutionary troops were active regularly in the entire area. The Lenape assisted the colonists, supplying the revolutionary army with warriors and scouts in exchange for food supplies and the promise of a role at the head of a future Native American state. The Treaty of Easton signed by the Lenape and the British in 1766 had required that the Lenape move to Pennsylvania. Wanting to recoup rights lost thereby to the British, the Lenape were the first tribe to enter into a treaty with the emerging government of the United States.Treaty of 1778, America's First Indian Treaty, accessed December 31, 2006. In 1781, General Rochambeau built a large bakery operation at Chatham as a subterfuge that could be interpreted as his plan to stay in Chatham for an extended amount of time, in order to distract from the fact that his troops were marching south toward Yorktown.Selig, Robert A. The Washington - Rochambeau Revolutionary Route In The State Of New Jersey, 1781 - 1783 An Historical and Architectural Survey Volume I, New Jersey Historic Trust, 2006. Accessed July 12, 2020. "The establishment of large bakery operations could be interpreted as a sign that the army was going to stay in a given location for a while. In the context of the 1781, the bake ovens in Chatham, though necessary to feed the army on the march, also served an important function in the scheme of confirming in Clinton in the conviction that New York was the intended target of the campaign."
