What were some of the treaties/alliances with foreign countries during civil war?

My topic for the civil war project is foreign policy. The part that I have to research is on the treaties or any alliances with the United States and any foreign countries during that time. I have done research and found a couple of helpful things but I do not have enough information to make a textbook entry which is part of the project. Can someone please help and give tips on how to write the textbook entry (i'm not the best writer)?
