Caught between the powerful commercial ports of New York and Pennsylvania, New Jersey spent the Confederation years at a disadvantage. With no authority to levy its own tariffs, the state watched its neighbors profit from trade while it absorbed the costs. The proposed Constitution promised a stronger federal system—one that would regulate interstate commerce fairly and end the economic imbalance New Jersey had long endured.
When Delaware and Pennsylvania ratified the Constitution, New Jersey moved quickly. The state’s convention met in Trenton, and the delegates acted with remarkable unity. The official minutes record no debate at all, noting instead the “absence of debate and the ready adoption” of the new framework—clear evidence of widespread dissatisfaction with the Articles of Confederation and broad support for change.
On December 18, 1787, New Jersey unanimously approved the Constitution, becoming the third state to join the Union. Its swift ratification reflected both practical economic interests and a firm belief that a stronger national government was essential for the young republic’s future.
