When it comes to the first draft of the Articles of Confederation, there were a few key differences compared to the final version. One major difference was the absence of an executive branch in the initial draft. The first draft only had a unicameral legislature, meaning there was no separate branch for executing laws or enforcing them. This was later revised in the final version to include an executive branch. If you have any more questions or if there's anything else you'd like to know, feel free to ask!
