What were the advantages (strengths) and disadvantages (weaknesses) of both the confederacy and union during the war?

At the beginning of the Civil War in 1861, the Union and the Confederation had very different characteristics, which gave them relative advantages over one another in different fields:

-With regard to the military field, the Confederation had more experienced military personnel in its command posts, such as Robert E. Lee or Joseph E. Johnson. For its part, the Union had a greater number of men, since it controlled the most populated states. Therefore, strategically the Confederation had an advantage, but in terms of military impact, it was the Union who led the way.

-Economically, the Union was more advanced than the Confederation, since it was a highly industrialized territory, which could develop armaments in its factories and trade industrialized products abroad. The Confederation, on the other hand, did not have a consolidated industrial production, but its production was agricultural, and depended on slave labor.

- Regarding international relations, although the Confederation had the tacit support of France and Great Britain, the Union exerted sufficient pressure so that they do not get involved in the war.
