Trenton is the capital city of the State of New Jersey and the county seat of Mercer County. The city is officially considered to be within the Greater New York City Combined Statistical Area. As of the 2010 United States Census, Trenton had a population of 84,913, making it the state's 10th-largest municipality. The Census Bureau estimated that the city's population was 84,899 in 2011.
Trenton dates back at least to June 3, 1719, when mention was made of a constable being appointed for Trenton, while the area was still part of Hunterdon County. Boundaries were recorded for Trenton Township as of March 2, 1720, a courthouse and jail were constructed in Trenton around 1720 and the Freeholders of Hunterdon County met annually in Trenton. Trenton became New Jersey's capital as of November 25, 1790, and the City of Trenton was formed within Trenton Township on November 13, 1792. Trenton Township was incorporated as one of New Jersey's initial group of 104 townships by an Act of the New Jersey Legislature on February 21, 1798. Portions of the township were taken on February 22, 1834, to form Ewing Township. On April 10, 1837, Trenton Township was dissolved and became part of Trenton city. A series of annexations took place over a 50-year period, with the city absorbing South Trenton borough (April 14, 1851), portions of Nottingham Township (April 14, 1856), both the Borough of Chambersburg Township and Millham Township (both on March 30, 1888), as well as Wilbur Borough (February 28, 1898).
The first settlement which would become Trenton was established by Quakers in 1679, in the region then called the Falls of the Delaware, led by Mahlon Stacy from Handsworth, Sheffield, UK. Quakers were being persecuted in England at this time and North America provided the perfect opportunity to exercise their religious freedom.
By 1719, the town adopted the name "Trent-towne", after William Trent, one of its leading landholders who purchased much of the surrounding land from Stacy's family. This name later was shortened to "Trenton".
During the American Revolutionary War, the city was the site of the Battle of Trenton, George Washington's first military victory. On December 26, 1776, Washington and his army, after crossing the icy Delaware River to Trenton, defeated the Hessian troops garrisoned there. After the war, Trenton was briefly the national capital of the United States in November and December 1784. The city was considered as a permanent capital for the new country, but the southern states favored a location south of the Mason-Dixon Line.
Trenton became the state capital in 1790, but prior to that year the Legislature often met here. The town was incorporated in 1792.
During the War of 1812, the primary hospital facility for the U.S. Army was at a temporary location on Broad Street.
Throughout the 19th Century, Trenton grew steadily, as Europeans came to work in its pottery and wire rope mills. In 1837, with the population now too large for government by council, a new mayoral government was adopted, with by-laws that remain in operation to this day.
Lamberton, The Port of Trenton
“For almost a century, from the early 1750s into the 1840s, first fishing and then river transportation sustained Lamberton as a river town on the Delaware and as Trenton’s port. . . .Today Trenton’s historical relationship to the Delaware River and its reliance in the preindustrial era on the port of Lamberton as a connection to the outside world are seldom appreciated. Yet before the canals and railroads came to rule the regional transportation network in the mid-19th century, the river provided the primary link between the city and the surround region. . . . For those traveling up the river, Trenton—and more specifically, Lamberton—lay at the head of navigation and head of tide.” (Source: Lamberton, The Port of Trenton Accessed 7 Mar 2014)
Lamberton is now sometimes known as South Trenton.
