Once the immediate task of winning the war had passed, states began to look to their own interests rather than those of the whole country. By the mid-1780s, states were refusing to provide Congress with funding, which meant the Confederation government could not pay the interest on its foreign debt, pay soldiers stationed along the Ohio River or defend American navigation rights on the Mississippi River against Spanish interference. In 1782, Rhode Island vetoed an amendment that would have allowed Congress to levy taxes on imports to pay off federal debts. A second attempt was made to approve a federal impost in 1785; however, this time it was New York which disapproved.
