Whose state's rights were most threatened by the Virginia Plan?

The Virginia Plan primarily threatened the state's rights of smaller states. By proposing a strong central government with representation based on population, it favored larger states like Virginia and Pennsylvania, thereby diminishing the influence and power of smaller states such as New Jersey and Delaware. Smaller states feared that this model would lead to a loss of their interests and autonomy in the new federal system. This concern ultimately contributed to the creation of the New Jersey Plan, which aimed to protect the rights of smaller states.
