The articles gave the government no separation of powers. The government was too weak, the Articles left much of the power to the states (if I remember correctly, states basically went by their own state constitution). Congress didn't have the power to tax. To change the Articles, it had to be decided unanimously by all states. Also, 9 out of the 13 states had to approve any major law before it was passed and Congress couldn't regulate commerce. There was no president to lead, no established court system, and every state had only one vote in congress.
Basically, the articles created no separate executive department to carry out and enforce the acts of Congress and no national court system to interpret the meaning of laws.

They worried that Lincoln would try to end slavery in the United States.
==========================================================
Explanation:
The issue of slavery was debated and fought over for many years before the election of 1860. It was only until Lincoln became president that sparked the southern states to secede, which led to the Civil War. Proof of this is found in the many Declaration of Secession documents produced by each state that left the union. This is basically a document explaining why they left the United States to form the Confederate States of America (CSA) aka the Confederacy.
In modern times, some people mistakenly claim that the Civil War wasn't over slavery but rather states' rights. This is simply false. The documents I mentioned prove that slavery was the core issue. More proof is the various states having issues with the fugitive slave act, in that the northern states didn't really adhere to the law to the level of the southern states' liking. I guess you could argue that states' rights were involved, but specifically the south fought to have the right to own slaves. In short, it's all about getting the correct context. Expanding that context, simply look at the decades preceding the war and notice all of the tension involving whether a new state was a free state vs a slave state.
