Why did small states oppose the Virginia Plan?
The Virginia Plan gave too much power to the large states.
The Virginia plan created a legislative branch based entirely on population. Each state received a number of representatives based on the population in that state.
The Virginia plan would have given dominance and legislative power to the large states at the expense of the small states.
The compromise was found in the model of the Iroquois Confederation. The Iroquois had two legislative bodies. One was based on population the number of long houses. The second was the council of chiefs. In the council of chiefs each tribe was equal with two representatives.
