The Articles of Confederation allowed each state only one vote in Congress. Which shows why some states were concerned with changing this?

The Articles of Confederation, sanctioned in 1777 by the Continental Congress, were the first fundamental norm of the United States, just after the American Revolution had begun and the independence of the nation from Great Britain was declared.

Through these Articles the political structure of the United States was organized, which established a collegiate government through the Congress of the Confederacy, which was made up equally by a representative from each of the 13 states of the country.

However, when it was proposed to modify this situation, the less populated states spoke out against it. This was so because the most populated states proposed a system of proportional representation based on the population of each state, with which the smaller states would see their political power reduced compared to larger states, such as Virginia or Massachusetts.
