The New Jersey Plan proposed by William Paterson at the Constitutional Convention in 1787 was different from the Articles of Confederation in several ways:
The New Jersey Plan proposed a unicameral legislature with equal representation for each state, whereas the Articles of Confederation had a unicameral legislature with each state having only one vote.
The New Jersey Plan gave the federal government more power to regulate trade and raise revenue, whereas the Articles of Confederation had limited powers in these areas.
The New Jersey Plan proposed a federal executive consisting of more than one person, whereas the Articles of Confederation did not have a federal executive at all.
The New Jersey Plan gave the federal government the power to enforce laws and resolve disputes between the states, whereas the Articles of Confederation had no such provision.
Overall, the New Jersey Plan represented an effort to strengthen the federal government and address some of the weaknesses of the Articles of Confederation.
