At the Constitutional Convention, smaller states eagerly supported the New Jersey Plan.

Explanation:

The Constitutional Convention was held on June 15, 1787 in Philadelphia, with the objective of modifying the Articles of Confederation, although it finally sanctioned the United States Constitution as the new maximum law for the country.

Among the issues to be dealt with in the convention was that of a better organization of the legislative power, which would be made up of representatives of the states. The problem arose regarding the number of representatives that each state would have in it, thus emerging two predominant plans: the Virginia Plan, by which Congress would have a representation proportional to the population of each state; and the New Jersey Plan, by which representation would be equal for each state, favoring smaller states, that would have equal representation than more populated states.

Finally, the solution to this controversy was to amalgamate both proposals, establishing a bicameral Congress, with one chamber with proportional representation and the other with equal representation.
