Why Trenton Is New Jersey’s Capital: A Short History
How Trenton became New Jersey's capital, its two months as the capital of the United States in 1784, and the 1792 State House at its center.
Trenton has been the seat of New Jersey’s government for more than two centuries, and for a brief, remarkable stretch it was the seat of the entire nation’s. Here is how the capital city earned its title.
Two months as the nation’s capital
In the fall of 1784, the Confederation Congress, the governing body of the young United States under the Articles of Confederation, met in Trenton at the French Arms Tavern. For about two months, from November 1 to December 24, 1784, this small river town was effectively the capital of the United States. Figures who would shape the country passed through, including James Monroe, a future president, and John Jay, the future first chief justice of the Supreme Court.
Trenton lobbied to become the permanent national capital, offering land and money. Northern states favored it, but southern states pushed for a location farther south, and the compromise that followed eventually placed the capital on the Potomac. Trenton’s turn on the national stage was over almost as soon as it began.
New Jersey’s capital since 1790
The consolation was significant. On November 25, 1790, Trenton became the capital of New Jersey, chosen in part for its central location between New York and Philadelphia and its place in Revolutionary history as the site of Washington’s 1776 victory. The City of Trenton was formally established in 1792.
The State House
At the center of it all is the New Jersey State House on West State Street. First built in 1792 and expanded many times since, it is among the oldest state capitol buildings in continuous legislative use in the country. Its gold dome is a downtown landmark, and the building still houses the Legislature and the governor’s offices. The Legislature offers public tours; check the New Jersey Legislature for current information.
A government town
That history still defines Trenton today. State government is the dominant employer downtown, and the rhythms of the Legislature, the courts, and the executive branch shape daily life in the capital. We follow those institutions closely in our Politics & Government section, and you can trace the city’s Revolutionary roots in our guide to the Battle of Trenton.
