Why did America experience Civil War
America experienced Civil War because of the different worldviews of states on slavery, labor, and society. The main topics of concern were such complex issues as expansionism, sectionalism, slavery, and politics. With the expansion of the Republic, question arose about whether the new states would belong to “free states”, or “slave states,” and these confrontations and controversies were also backed with divergent culture of the North and the South. Slaveholders were losing their power, which ignited desire to fight for slaves; in addition the cultures of the South and the North were so different that they were not at all consistent with each other culturally. Thus, the confrontation of economies, societies, and many other divisive issues of sectionalism have pushed America into the Civil War of 1861 – 1865. However, the main cause of Civil War was the difference in view of the North and the South on slavery, society, and labor. 
The four conflicting worldviews originated from four parts of the Republic, namely Northeast, Northwest, Upper South, and Southwest. Northeast was famous for industrialization, growing economy and population; Northwest was the expanding region of farmers; Upper South had plantations, and decreasing economic environment; and Southwest was famous for cotton industry. Not only these four divergent regions different in economic aspects, but also visions on society were completely different. However, the Northern parts shared the view of free labor, while the Southern parts were more prone to slave labor. The confrontation of attitudes between the North and the South reached its peak in the middle of the 19th century and resulted in Civil War. 
Although the Constitution of the young Republic formulated general notion of labor and work, it was not enough to quell slave trade and slavery at large. Several steps had been made before the war aimed at diminishing conflict, such as Missouri Compromise and the Compromise of 1850, which demonstrated the desire to maintain peaceful and unified nation, however these were not enough to quell political and social confrontations.
Although there is not one single reason for the clash, distinct views on labor and society are amongst the major circumstances. These and other circumstances that moved separate parts of the country to an aggressive clash gained momentum in 1840-50’s, and by mid-19th century they were so strong that no political treaty of compromise could settle them down. The democrats pressing from the North, the acquisition of new lands, and the breakdown of the two-party system, - all made the situation in the country uncontrollable. With the rise of the Republican Party and the election of Abraham Lincoln, the Southerners exhibited even greater opposition. 
The causes of this opposition are enclosed in the historical development and different lifestyles of North and South. The Southern parts were mainly agricultural and needed much labor force. Slaves were very profitable workers, because they were very cheap. Thus, the South was not at all happy with the democratic free labor beliefs from the North, because it meant real threats to Southern magnates and potentates. However, democracy was inconsistent with South not only because of the economic issues, but also because views on labor and culture mentioned above. Those who gained great profits from slaveholding constituted a minority. In other words, Southern farmers accepted slave labor and slave trade, even though they were not slave holders themselves. Those farmers as well as other folk depended on magnates because of the job opportunities, and thus supported the way the elite ran business. Thus, by mid-19th century, those slave magnates experienced high pressure from the democratic North. Although separating from Northern parts might be an objective decision, the South depended much on the North for various merchandized goods, commercial services, manufactured products, and loans. This way, the South could not depart from the North, but could not accept the Northern moral and political beliefs. 
In addition to economic dependence on the North, Southern states had also lost balance of power in Senate, this way becoming a minority in all its meanings. Eventually, in 1960 South Carolina seceded from the Union in an attempt to unite the other Southern states against the North and their beliefs. Altogether, seven states including South Carolina seceded by 1861, and formed their own provisional constitution for Confederate States of America. This way, the opponents have been clearly defined. A month later, President Lincoln claimed he intends to use force to maintain federal property regardless of the willful secession of the Southern states. 
Generally speaking, America experienced Civil War because of the disagreements among Northerners and the South. In simple terms, North was more industrialized and that is why did not need slaves much. In the South, contrarily, vast plantations needed many workers to take care of them. Slavery was the best option, since it was cheap. With the rise of democracy and morality in the North, slavery was more and more questioned, and eventually antislavery movement was formed. The South disagreed, and decided to secede, but the North wanted to maintain the land. The Federal Government had no choice but to maintain federal property, and to use force. Thus, the main reasons why America experienced Civil War was the disagreement of views on slavery, society, and labor.
