Question

What did it take to make an Amendment or change the Articles of Confederation?

Answer 1

2/3 of the house of representatives need to approve it and 3/4 of the states need to approve it

Answer 2

The document was also practically impossible to amend. The Articles required unanimous consent to any amendment, so all 13 states would need to agree on a change. Given the rivalries between the states, that rule made the Articles impossible to adapt after the war ended with Britain in 1783.
