Explanation:

The Articles of Confederation (1781), the first US written Constitution, established a confederacy in which states had sovereignty and independence and the government had few powers that proved to be inefficient to lead the newborn nation.

Under this document, the central government consisted of an unicameral Congress that lacked important enforcement powers such as the power to tax states directly (it could raise money only by asking the states for funds, which had the option to reject the request, by borrowing from foreign governments, or by selling western lands), to draft soldiers and to regulate commerce.
