Congress was given the sole power to deal with foreign countries, to settle disputes between the states, to decide admiralty cases (those involving ships at sea) to declare war, and to make peace. It could also coin money, run the postal service, establish weights and measurement and trade with the Indians outside of the states. It could borrow money and request each state to contribute money in proportion to the value of the property of the state. Congress could only request financial support from the states but if a state refused to help there was nothing the congress could do.
