The union was industrial as they had tons of factories producing war supplies and the Confedracy was Agricultural since they used slaves to do all the work and the Union had the largest cities as they owned New York city, Philiedlphia etc, the Union had the larger army as they had the larger population, the Union had the larger Navy as they were the ones to use Iron Clads to blockade the South, they both were Americans and wanted the better for America ( as they see it ) They both wanted to isolate themselves from the rest of the world, and they both wanted to restore the Union under there control. The southern states depended on the slaves and weren't just gonna let them go just cause the unions says so, and the Union wants to preserve the union and make it slave free. Union values democracy and freedom for all, as the South values White supremacy, the purpose of the war was really to see if slavery exists in the United states of america or not.
