The power to create land ordinances

Explanation:

The Articles of Confederation were the first US Constitution. The article created a loose confederation of sovereign states with a weak central government. Because of that, the Congress did not have much power, because most of the power was left with the state governments.

One of the powers that Congress had was the power to create land ordinances. An example is the Northwest Ordinance of 1787 that was the single most important piece of legislation in that period.
