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.^[24][25] 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.^[26] 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.^[27]

In the 2020 United States census, Trenton was the state's 10th-most-populous municipality,^[28] with a population of 90,871,^[13][14] an increase of 5,958 (+7.0%) from the 2010 census count of 84,913,^[29][30] which in turn had reflected a decline of 490 (−0.6%) from the 85,403 counted in the 2000 census.^[31] The Census Bureau's Population Estimates Program calculated that the city's population was 89,661 in 2022,^[13] ranking the city the 382nd-most-populous in the country.^[15] Trenton is the only city in New Jersey that serves three separate commuter rail transit systems (Amtrak, NJ Transit, and SEPTA), and the city has encouraged a spate of transit-oriented development since 2010.^[32]

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.^[33] A courthouse and jail were constructed in Trenton around 1720, and the Freeholders of Hunterdon County met annually in Trenton.^[34]

Abraham Hunt was appointed in 1764 as Trenton's first Postmaster.^[35][36] On November 25, 1790, Trenton became New Jersey's capital, and by November 13, 1792, the City of Trenton was formed within Trenton Township. 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. On February 22, 1834, portions of Trenton Township were taken to form Ewing Township. The remaining portion of Trenton Township was absorbed by the city on April 10, 1837. A series of annexations took place over a 50-year period with the city absorbing South Trenton (April 14, 1851), portions of Nottingham Township (April 14, 1856), Chambersburg Township and Millham Township (both on March 30, 1888), and Wilbur (February 28, 1898). Portions of Ewing Township and Hamilton Township were annexed to Trenton on March 23, 1900.^[33][37]

The earliest known inhabitants of the area that is today Trenton were the Lenape Native Americans,^[38] specifically the Axion band who were the largest tribe on the Delaware River in the mid-17th century.^[39]

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.^[40]

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".^[41][42][43]

The first municipal boundaries were recorded on March 2, 1720, and a courthouse and jail were constructed around the same time.^[44]

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.^[35][36]

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.^[45] The second battle of Trenton, Battle of the Assunpink Creek, was fought here on January 2, 1777.^[46] After the war, the Congress of the Confederation met for two months at the French Arms Tavern from November 1, 1784, to December 24, 1784.^[25] While the city was preferred by New England and other northern states as a permanent capital for the new country, the southern states ultimately prevailed in their choice of a location south of the Mason–Dixon line.^[47] On April 21, 1789, the city hosted a reception for George Washington on his journey to New York City for his first inauguration.^[48] The Trenton Battle Monument, a 150-foot (46 m) granite column topped with a statue of George Washington, was built in 1893 to commemorate the battle.^[49]

Trenton became the state capital in 1790, but prior to that year the New Jersey Legislature often met in the city.^[50] The city was incorporated on November 13, 1792.^[33] In 1792, the New Jersey State House was built, making it the third-oldest state house in the country.^[49] In 1799, the federal government relocated its offices to Trenton for a period of several months, following an outbreak of yellow fever in the then-capital of Philadelphia.^[51]

During the War of 1812, the United States Army's primary hospital was at a site on Broad Street.^[52]

Trenton had maintained an iron industry since the 1730s and a pottery industry since at least 1723. The completion of both the Delaware and Raritan Canal and the Camden and Amboy Railroad in the 1830s spurred industrial development in Trenton. In 1845, industrialist Peter Cooper opened a rolling mill. In 1848, engineer John Roebling moved his wire rope mill to the city, where suspension cables for bridges were manufactured, including the Brooklyn Bridge. In the late 19th century, Walter Scott Lenox was internationally recognized for the fine china made in his Trenton factory. Throughout the 19th century, Trenton grew steadily, as European immigrants came to work in its pottery and wire rope mills. Trenton became known as an industrial hub for railroads, trucking, rubber, plastics, metalworking, electrical, automobile parts, glass, and textiles industries.^[49]

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.^[53] During the latter half of the century, Trenton annexed multiple municipalities: South Trenton Borough on April 14, 1851, portions of Nottingham Township on April 14, 1856, Chambersburg and Millham Township on March 30, 1888, and Wilbur borough on February 28, 1898.^[44]

In 1855, the College of New Jersey was founded in Trenton. In 1865, Rider University was also founded in Trenton. Mercer Community College began in Trenton in 1966.^[49]

The Trenton Six were a group of black men arrested for the alleged murder of an elderly white shopkeeper in January 1948 with a soda bottle. They were arrested without warrants, denied lawyers and sentenced to death based on what were described as coerced confessions. With the involvement of the Communist Party and the NAACP, there were several appeals, resulting in a total of four trials. Eventually the accused men (with the exception of one who died in prison) were released. The incident was the subject of the book Jersey Justice: The Story of the Trenton Six, written by Cathy Knepper.^[54][55]

In the 1950s, the State of New Jersey purchased a large portion of what was then Stacy Park, a large riverfront park located next to downtown that contained large open lawns, landscaping, and promenades. Much of the park was demolished to make way for the construction of Route 29, despite the protests toward its construction. After it was built, the area was then mostly filled with parking lots and scattered state office buildings, disconnecting the city from the riverfront.^[56]

The Trenton Riots of 1968 were a major civil disturbance that took place during the week following the assassination of civil rights leader Martin Luther King Jr. in Memphis on April 4. Race riots broke out nationwide following the murder of the civil rights activist. More than 200 Trenton businesses, mostly in Downtown, were ransacked and burned. More than 300 people, most of them young black men, were arrested on charges ranging from assault and arson to looting and violating the mayor's emergency curfew. In addition to 16 injured policemen, 15 firefighters were treated at city hospitals for injuries suffered while fighting raging blazes or inflicted by rioters. Area residents pulled false alarms and would then throw bricks at firefighters responding to the alarm boxes. This experience, along with similar experiences in other major cities, effectively ended the use of open-cab fire engines. As an interim measure, the Trenton Fire Department fabricated temporary cab enclosures from steel deck plating until new equipment could be obtained. The losses incurred by downtown businesses were initially estimated by the city to be $7 million, but the total of insurance claims and settlements came to $2.5 million.^[57]

Trenton's Battle Monument neighborhood was hardest hit. Since the 1950s, North Trenton had witnessed a steady exodus of middle-class residents, and the riots spelled the end for North Trenton. By the 1970s, the region had become one of the most blighted and crime-ridden in the city.^[58]

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%).^[2][3] In terms of land area, Trenton is also the second-smallest of the United States capital cities, behind Annapolis, Maryland.^[59]

Several bridges across the Delaware River connect Trenton to Morrisville, Pennsylvania, all of which are operated by the Delaware River Joint Toll Bridge Commission.^[60] The Trenton–Morrisville Toll Bridge, originally constructed in 1952, stretches 1,324 feet (404 m), carrying U.S. Route 1.^[61] The Lower Trenton Bridge, bearing the legend "Trenton Makes The World Takes Bridge", is a 1,022-foot (312 m) span that was constructed in 1928 on the site of a bridge that dates back to 1804.^[62] The Calhoun Street Bridge, dating back to 1884, is 1,274 feet (388 m) long.^[63]

Trenton is located near the geographic center of the state, which is located 5 miles (8.0 km) southeast of the city.^[64][65] The city is sometimes included as part of North Jersey and as the southernmost city of the Tri-State Region, while others consider it a part of South Jersey and thus, the northernmost city of the Delaware Valley.^[66]

However, Mercer County constitutes its own metropolitan statistical area, the Trenton-Princeton MSA.^[26] Locals consider Trenton to be a part of Central Jersey, and thus part of neither region. They are generally split as to whether they are within New York or Philadelphia's sphere of influence. While it is geographically closer to Philadelphia, many people who have recently moved to the area commute to New York City, and have moved there to escape the New York region's high housing costs.^{[citation needed]}

Trenton is one of two state capitals that border another state—the other being Carson City, Nevada.^[67] It is also one of the seven state capitals located within the Piedmont Plateau.

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.^[68][69][70]

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.

Trenton is home to numerous neighborhoods and sub-neighborhoods. The main neighborhoods are taken from the four cardinal directions (North, South, East, and West). Trenton was once home to large Italian, Hungarian, and Jewish communities, but, since the 1950s, demographic shifts have changed the city into a relatively segregated urban enclave of middle and lower income African Americans and newer immigrants, many of whom arrive from Latin America. Italians are scattered throughout the city, but a distinct Italian community is centered in the Chambersburg neighborhood, in South Trenton.^[71] This community has been in decline since the 1970s, largely due to economic and social shifts to the suburbs surrounding the city. Today Chambersburg has a large Latino community. Many of the Latino immigrants are from Mexico, Guatemala and Nicaragua. There is also a significant and growing Asian community in the Chambersburg neighborhood primarily made up of Burmese and Bhutanese/Nepali refugees.

The North Ward, once a mecca for the city's middle class, is now one of the most economically distressed, torn apart by race riots following the assassination of Martin Luther King Jr. in 1968. Nonetheless, the area still retains many important architectural and historic sites. North Trenton still has a large Polish-American neighborhood that borders Lawrence Township, many of whom attend St. Hedwig's Roman Catholic Church on Brunswick Avenue. St. Hedwig's church was built in 1904 by Polish immigrants, many of whose families still attend the church. North Trenton is also home to the historic Shiloh Baptist Church—one of the largest houses of worship in Trenton and the oldest African American church in the city, founded in 1888.^[72] The church is currently pastored by Rev. Darrell L. Armstrong, who carried the Olympic torch in 2002 for the Winter Olympics in Salt Lake City. Also located just at the southern tip of North Trenton is the city's Battle Monument, also known as "Five Points". It is a 150 ft (46 m) structure that marks the spot where George Washington's Continental Army launched the Battle of Trenton during the American Revolutionary War. It faces downtown Trenton and is a symbol of the city's historic past.^[73]

South Ward is a diverse neighborhood, home to many Latin American, Italian-American, and African American residents.^[74]

East Ward is the smallest neighborhood in Trenton and is home to the Trenton Transit Center and Trenton Central High School. The Chambersburg neighborhood is within the East Ward and was once noted in the region as a destination for its many Italian restaurants and pizzerias. With changing demographics, many of these businesses have either closed or relocated to suburban locations. West Ward is the home of Trenton's more suburban neighborhoods.

Neighborhoods in the city include:^[75]

According to the Köppen climate classification, Trenton lies in the transition from a cooler humid continental climate (Dfa) and the warmer humid subtropical (Cfa), and precipitation fairly evenly distributed through the year. The Cfa climate is the result of adiabatic warming of the Appalachians, low altitude and proximity to the coast without being on the immediate edge for moderate temperatures.^[76]

Summers are hot and humid, with a July daily average of 76.3 °F (24.6 °C); temperatures reaching or exceeding 90 °F (32 °C) occur on 21.8 days.^[77] Episodes of extreme heat and humidity can occur with heat index values reaching 100 °F (38 °C). Extremes in air temperature have ranged from −14 °F (−26 °C) on February 9, 1934, up to 106 °F (41 °C) as recently as July 22, 2011.^[78] However, air temperatures reaching 0 °F (−18 °C) or 100 °F (38 °C) are uncommon.

Winters are cold and damp: the daily average temperature in January is 32.0 °F (0.0 °C),^[77] and temperatures at or below 10 °F (−12 °C) occur on 3.9 nights annually, while there are 17 days where the temperature fails to rise above freezing.^[79] Episodes of extreme cold and wind can occur with wind chill values below 0 °F (−18 °C), every few years. The plant hardiness zone at the Trenton Municipal Court is 7a with an average annual extreme minimum air temperature of 1.2 °F (−17.1 °C).^[80]

The average precipitation is 45.47 inches (115 cm) per year, which is fairly evenly distributed through the year.^[77][79] The driest month on average is February, with 2.63 in (67 mm) of precipitation on average, while the wettest month is July with 4.39 in (11 cm) of rainfall on average which corresponds with the annual peak in thunderstorm activity.^[77][79] The all-time single-day rainfall record is 7.25 in (18.4 cm) on September 16, 1999, during the passage of Hurricane Floyd.^[79] The all-time monthly rainfall record is 14.55 in (37.0 cm) in August 1955, due to the passage of Hurricane Connie and Hurricane Diane. The wettest year on record was 1996, when 67.90 in (172 cm) of precipitation fell. On the flip side, the driest month on record was October 1963, when only 0.05 in (0.1 cm) of rain was recorded. The 28.79 in (73 cm) of precipitation recorded in 1957 were the lowest ever for the city.^[81]

Snowfall can vary even more year to year. The average seasonal (November–April) snowfall total is 24 to 30 inches (61 to 76 cm), but has ranged from as low as 2 in (5.1 cm) in the winter of 1918–1919 to as high as 76.5 in (194.3 cm) in 1995–1996, which included the greatest single-storm snowfall, the Blizzard of January 7–8, 1996, when 24.2 inches (61.5 cm) of snow fell.^[82] The average snowiest month is February which corresponds with the annual peak in nor'easter activity.

The 2010 United States census counted 84,913 people, 28,578 households, and 17,747 families in the city. The population density was 11,101.9 per square mile (4,286.5/km²). There were 33,035 housing units at an average density of 4,319.2 per square mile (1,667.7/km²). The racial makeup was 26.56% (22,549) White, 52.01% (44,160) Black or African American, 0.70% (598) Native American, 1.19% (1,013) Asian, 0.13% (110) Pacific Islander, 15.31% (13,003) from other races, and 4.10% (3,480) from two or more races. Hispanic or Latino of any race were 33.71% (28,621) of the population.^[29]

Of the 28,578 households, 32.0% had children under the age of 18; 25.1% were married couples living together; 28.1% had a female householder with no husband present and 37.9% were non-families. Of all households, 30.8% were made up of individuals and 9.1% had someone living alone who was 65 years of age or older. The average household size was 2.79 and the average family size was 3.40.^[29]

25.1% of the population were under the age of 18, 11.0% from 18 to 24, 32.5% from 25 to 44, 22.6% from 45 to 64, and 8.8% who were 65 years of age or older. The median age was 32.6 years. For every 100 females, the population had 106.5 males. For every 100 females ages 18 and older there were 107.2 males.^[29]

The Census Bureau's 2006–2010 American Community Survey showed that (in 2010 inflation-adjusted dollars) median household income was $36,601 (with a margin of error of +/− $1,485) and the median family income was $41,491 (+/− $2,778). Males had a median income of $29,884 (+/− $1,715) versus $31,319 (+/− $2,398) for females. The per capita income for the city was $17,400 (+/− $571). About 22.4% of families and 24.5% of the population were below the poverty line, including 36.3% of those under age 18 and 17.5% of those age 65 or over.^[101]

Trenton was a major manufacturing center in the late 19th and early 20th centuries. One relic of that era is the slogan "Trenton Makes, The World Takes", which is displayed on the Lower Free Bridge (just north of the Trenton–Morrisville Toll Bridge).^[102] The city adopted the slogan in 1917 to represent Trenton's then-leading role as a major manufacturing center for rubber, wire rope, ceramics and cigars. It was home to American Standard's largest plumbing fixture manufacturing facility.^[103]

Along with many other United States cities in the 1970s, Trenton fell on hard times when manufacturing and industrial jobs declined. Concurrently, state government agencies began leasing office space in the surrounding suburbs. State government leaders (particularly governors William Cahill and Brendan Byrne) attempted to revitalize the downtown area by making it the center of state government. Between 1982 and 1992, more than a dozen office buildings were constructed primarily by the state to house state offices.^[104] Today, Trenton's biggest employer is still the state of New Jersey. Each weekday, 20,000 state workers flood into the city from the surrounding suburbs.^[105]

Notable businesses of the thousands based in Trenton include Italian Peoples Bakery, a wholesale and retail bakery established in 1936.^[106] De Lorenzo's Tomato Pies and Papa's Tomato Pies were also fixtures of the city for many years, though both recently relocated to the suburbs.

Portions of Trenton are part of an Urban Enterprise Zone. The city was selected in 1983 as one of the initial group of 10 zones chosen to participate in the program.^[107] In addition to other benefits to encourage employment within the Zone, shoppers can take advantage of a reduced 3.3125% sales tax rate (half of the 6+5⁄8% rate charged statewide) at eligible merchants.^[108] Established in January 1986, the city's Urban Enterprise Zone status expires in December 2023.^[109]

The UEZ program in Trenton and four other original UEZ cities had been allowed to lapse as of January 1, 2017, after Governor Chris Christie, who called the program an "abject failure", vetoed a compromise bill that would have extended the status for two years.^[110] In May 2018, Governor Phil Murphy signed a law that reinstated the program in these five cities and extended the expiration date in other zones.^[111]

In 2018, the city had an average property tax bill of $3,274, the lowest in the county, compared to an average bill of $8,292 in Mercer County and $8,767 statewide.^[112][113] The city had the sixth-highest property tax rate in New Jersey, with an equalized rate of 5.264% in 2020, compared to 2.760% in the county as a whole and a statewide average of 2.279%.^[114]

Trenton has long been part of the Philadelphia television market. After the 2000 United States census, Trenton was shifted from the Philadelphia metropolitan statistical area to the New York metropolitan statistical area. With a similar shift by the New Haven, Connecticut, area to the New York area, they were the first two cases where metropolitan statistical areas differed from their defined Nielsen television markets.^[115]

Trenton was the site of the studios of the former public television station New Jersey Network.

Because of Trenton's near-equal distance to both New York City and Philadelphia, and because most homes in Mercer County receive network broadcasts from both cities, locals are sharply divided in fan loyalty between both cities. It is common to find Philadelphia's Phillies, Eagles, 76ers, Union and Flyers fans cheering (and arguing) right alongside fans of New York's Yankees, Mets, Nets, Knicks, Rangers, Islanders, Jets, Red Bulls and Giants or the New Jersey Devils.^[129]

Between 1948 and 1979, Trenton Speedway, located in adjacent Hamilton Township, hosted world class auto racing. Drivers such as Jim Clark, A. J.

• Cadwalader Park – Trenton's largest city park covering 109.5 acres (44.3 ha), it was designed by landscape architect Frederick Law Olmsted, who is most famous for designing New York City's Central Park.^[137]

Trenton is governed within the Faulkner Act, formally known as the Optional Municipal Charter Law, under the Mayor-Council system of municipal government, one of 79 municipalities (of the 564) statewide that use this form of government.^[138] The governing body is comprised of a mayor and a seven-member city council. Three city council members are elected at-large, and four come from each of four wards. The mayor and council members are elected concurrently on a non-partisan basis to four-year terms of office as part of the November general election.^{[8][139][140]}

In October 2020, the city council overrode a mayoral veto and shifted municipal elections from May to November, with proponents citing the increased turnout and savings to the city of $180,000 in each election cycle. The mayor and members of council all had their term-end dates extended by six months and moved to December 31 from June 30, 2022.^[141] The city retained a runoff provision that would have a December runoff in the event that the candidate with the highest number of votes does not obtain a majority.^[142]

As of 2023^[update], the mayor of Trenton is Reed Gusciora, whose term of office ends December 31, 2026; before taking office as mayor, Gusciora had served in the New Jersey General Assembly.^[143] Members of the city council are Jasi Edwards (at-large), Crystal Feliciano (at-large), Teska Frisby (West Ward), Yazminelly Gonzalez (at-large), Joseph A. Harrison (East Ward), Jenna Figueroa Kettenburg (South Ward) and Jennifer Williams (North Ward).^{[4][144][145][146][147][148]}

As they had not exceeded the minimum of 50 percent in the November 2022 general election, a run-off was held in December for the seats in the North and South Wards. Jennifer Williams won the North seat by a single vote against Algernon Ward,^[149] which made Williams the first transgender individual to be elected to a city council position in New Jersey history as well as being the first LGBTQ+ city council member in Trenton history.^[150] Jenna Figueroa Kettenburg won the South ward seat, defeating Damian G. Malave who had been ahead on Election Day but short of the cutoff, while a January 2023 runoff had Jasi Edwards, Crystal Feliciano and Yazminelly Gonzalez winning the three at-large seats.^{[146][147][151]}

In February 2023, Judge William Anklowitz of the New Jersey Superior Court heard a case for election challenges in the North Ward runoff election for both candidates Algernon Ward and Jennifer Williams. Three of the ballots Ward contested were all rejected because they were mail-in ballots that were returned without the required inner envelope. The other rejection Ward challenged was a case involving a cure letter that a voter sent to the wrong place, leading to it being not counted. Williams contested one ballot that was not counted due to it having both a vote for Ward and for Williams. Judge Anklowitz determined that the slash through Ward's vote signaled the voter's intention to vote for Williams and thus determined the vote should have been counted. These election challenges were heard following a recount that was held that did not change the outcome of the vote. Jennifer Williams thus remained to hold her seat on Trenton City Council for the North Ward seat.^[152]

In February 2022, the city council appointed Sonya Wilkins to fill the at-large seat expiring in December 2022 that had been held by Jerell A. Blakeley until he resigned from office the previous month to take a job outside the state.^[153]

On February 7, 2014, Tony F. Mack and his brother, Raphiel, were convicted by a federal jury of bribery, fraud and extortion, based on the details of their participation in a scheme to take money in exchange for helping get approvals to develop a downtown parking garage as part of a sting operation by law enforcement.^[154] Days after the conviction, the office of the New Jersey Attorney General filed motions to have Mack removed from office, as state law requires the removal of elected officials after convictions for corruption.^[155] Initially, Mack fought the removal of him from the office but on February 26, a superior court judge ordered his removal and any actions taken by Mack between February 7 and the 26th could have been reversed by Muschal.^[156] Previously, Mack's housing director quit after it was learned he had a theft conviction. His chief of staff was arrested trying to buy heroin. His half-brother, whose authority he elevated at the city water plant, was arrested on charges of stealing. His law director resigned after arguing with Mack over complying with open-records laws and potential violations of laws prohibiting city contracts to big campaign donors.^[157]

From February 7 to July 1, 2014, the acting mayor was George Muschal who retroactively assumed the office on that date due to Mack's felony conviction, who had taken office on July 1, 2010.^[158] Muschal, who was council president, was selected by the city council to serve as the interim mayor to finish the term.^[156]
