Asuccess of the articles of confederation was that it created a strong federal government. established a national army. established land ordinances. abolished slavery throughout the nation.

The Articles of Conferation has many flaws, but under those laws, the United States was able to pass the Northwest Ordnance, which organized territories and gave more control to state governments. Though the law abolished slavery, it only did so in about five states. Hope this helps!
