Examine the problems confronting the first government of the United States under the Articles of Confederation that led to the Constitutional Convention.

I have to write a thesis statement and outline on the above command. I'll have to write a five paragraph essay out of it, but so far I'm coming up one short. I can't find enough information for another paragraph. I have:
The Articles were a "firm league of friendship" with facts, and that the Articles were't able to enforce laws, tax, or regulate commerce (with facts).
I'm still looking, but if anyone could throw me a bone with a couple (or one) more fact(s) about the problems of the Articles... I'd totally appreciate it.
