Overview
Trenton is the capital city of the U.S. state of New Jersey and the county seat of Mercer County. It was the capital of the United States from November 1 until December 24, 1784. Trenton and Princeton are the two principal cities of the Trenton–Princeton metropolitan statistical area, which encompasses those cities and all of Mercer County for statistical purposes and constitutes part of the New York combined statistical area by the U.S. Census Bureau. However, Trenton directly borders the Philadelphia metropolitan area to its west, and the city was part of the Philadelphia combined statistical area from 1990 until 2000.

History
The earliest known inhabitants of the area that is today Trenton were the Lenape Native Americans, specifically the Axion band who were the largest tribe on the Delaware River in the mid-17th century. The first European settlement in what 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, England. Quakers were being persecuted in England at this time, and North America provided an 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 was later shortened to "Trenton". The first municipal boundaries were recorded on March 2, 1720, and a courthouse and jail were constructed around the same time. In 1758, the Old Barracks were built to house British soldiers during the French and Indian War. On January 19, 1764, Benjamin Franklin, Postmaster General of the colonies, appointed Abraham Hunt, a Lieutenant Colonel in the New Jersey Hunterdon County militia and prominent merchant in Trenton, as the city's first postmaster. Hunt was again appointed Trenton's postmaster on October 13, 1775, shortly after the American Revolutionary War broke out. During the American Revolutionary War, Trenton was the site of the Battle of Trenton. On December 25–26, 1776, George Washington and his army crossed the icy Delaware River to Trenton, where they defeated Hessian troops garrisoned there. The second battle of Trenton, Battle of the Assunpink Creek, was fought here on January 2, 1777. After the war, the Congress of the Confederation met for two months at the French Arms Tavern from November 1, 1784, to December…
Geography
According to the U.S. Census Bureau, the city had a total area of 8.21 square miles (21.25 km2), including 7.58 square miles (19.63 km2) of land and 0.63 square miles (1.62 km2) of water (7.62%). Trenton is located near the geographic center of the state, which is located southeast of the city. Mercer County constitutes its own metropolitan statistical area, the Trenton-Princeton MSA, which is part of the Tri-State Region. They are generally split as to whether they are within New York or Philadelphia's sphere of influence. While it is closer to Philadelphia, many people commute to New York City and have moved to Trenton to escape the New York region's high housing costs. Trenton is one of two state capitals that border another state—the other being Carson City, Nevada. Trenton borders Ewing Township, Hamilton Township and Lawrence Township in Mercer County; and Falls Township, Lower Makefield Township and Morrisville in Bucks County, Pennsylvania, across the Delaware River in Pennsylvania. The Northeast Corridor goes through Trenton. A straight line drawn between Center City, Philadelphia and Downtown Manhattan would pass within 2000 feet of the New Jersey State House. Several bridges across the Delaware River connect Trenton to Morrisville, Pennsylvania, all of which are operated by the Delaware River Joint Toll Bridge Commission. The Trenton–Morrisville Toll Bridge, originally constructed in 1952, stretches , carrying U.S. Route 1. The Lower Trenton Bridge, bearing the legend "TRENTON MAKES THE WORLD TAKES", is a span that was constructed in 1928 on the site of a bridge that dates back to 1804. The Calhoun Street Bridge, dating back to 1884, is long. Trenton is home to numerous neighborhoods and sub-neighborhoods. The main neighborhoods are…
