Civil war was inevitable and whatever the outcome on the battlefields, the rebuilding of the nation was also inevitable because although the North and South had irrevocable differences, it was in the mutual interest of the North, South and West to maintain a relationship based on symbiosis. Civil war and the rebuilding of the nation were inevitable. There was great diversity across the country within the three sections. Differences in opinions and rules regarding slavery, economic differences and civilizations are all examples of causes of civil war. However, rebuilding the nation was necessary, as all three sections needed each other to survive. Civil war was inevitable. Due to the great diversity between the North and the South, civil war was inevitable. Slavery was one of the many causes of the Civil War. This poses a moral problem because it concerns human beings and undermines individual freedom and democratic ideals. Slavery greatly distinguished the South from the North and was the main issue that divided the two sections. Economic differences also contributed to the civil war. The South had become agricultural and the North had become industrial. These economic differences led to sectional rivalries over issues such as slavery and protective tariffs. The interpretation of the Federal Union also differed between the two sections. The South insisted that the Federal Union had been created by the states; therefore, any state had the right to secede. The North thought otherwise; they believed that the people had created the Union and that no state had the right to secede. The South favored the extension of slavery to the West, while the North opposed it. Most of the West became economically linked to the North through a network of railroads and trade. Southerners realized that Western lands were unsuitable for growing cotton and that they were losing Western support and that the South would remain a minority section in the Union. The North and the South presented differences in civilization. A small aristocracy of influential planter families dominated Southern civilization, compared to the more dynamic and democratic Northern civilization. This difference in civilization made it difficult to understand each other's points of view, which aggravated the causes of the war. Finally, both in the North and in the South, the differences are exaggerated..
