The American Civil War, otherwise known as the war between the states, lasted for four (4) years. It began in 1861 and ended in 1865. This war was between the U.S and the 11 southern states that separated from America and formed the Confederate States of America. This essay will discuss the four main reasons believed to be the causes of the American Civil War. Those causes are, slavery in America in 1619, The Novel Uncle Tom’s Cabin that was written in 1852, Lincoln’s victory as president in 1860 and the attack on Fort Sumter on April 12th, 1861. Given the proper resources provided to us through modern day technology, these are the four reasons believed to have played a vital role in the start of the American Civil War.One of the main causes believed to begin the American Civil war is slavery. Slavery in America was first introduced by the Dutch who had captured Africans and brought them to America. When the Dutch did this they planted the seeds of slavery in America. Little did they know that this was going to turn into a nightmare that ended up dividing the nation. “Those who deny freedom to others deserve it not for themselves – Abraham Lincoln”. Some 6 to 7 million slaves were estimated to have been brought to the “New World” during the 18th century. Slavery became a big problem later on in America when people realized how bad it was through the book Uncle Tom’s cabin and through other media sources. As a result of this there was an outbreak in rebellions and antislavery movements which caused an uprise between the north and south about whether slavery should be kept or not, which eventually led to the American civil war beginning. Uncle Tom’s Cabin is an anti slavery novel written by a woman named Harriet Beecher Stowe. This novel was published in 1852. The book takes place in the mid 19th century on a plantation in Kentucky owned by the Shelby family. It focused on the life of a black slave, Uncle Tom. According to Anne Douglas in association with Random Penguin House “Perhaps the most powerful document in the history of American abolitionism, this controversial novel goaded thousands of readers to take a stand on the issue of slavery and played a major political and social role in the Civil War period.” Uncle Tom’s Cabin contributed greatly to the start of the American Civil War because the book told people what the political speeches, tracts and newspapers at that time could not. Harriet Beecher Stowe made it easy for readers to read about the life of a slave and her personal style of writing made it easier for people to decide what they wanted in America more than they would listening to a politician giving a speech.The victory of President Lincoln on March 4th, 1861 was a trigger of the American Civil War because once an antislavery president was in power, and the south had already prepared for secession of withdrawal, they had little to no choice but to leave the Union. According to history.com “When Republican candidate Abraham Lincoln was elected as president, Within three months, seven southern states had seceded to form the Confederate States of America” The inauguration of president Lincoln played a vital role in the American Civil War because when he was inaugurated the Confederacy knew that Abraham Lincoln wanted to get rid of slavery. Lincoln is elected as president without one vote from the southern states and since the majority of votes were coming from the Northern states, which had the largest population, the Republican party won the vote. This drove South Carolina to secede from the United States and they were followed by many other southern states which formed the Confederate States of America. After these states had left America they became defensive of their country and attacked a Union fort named Fort Sumter in Charleston South Carolina which was in their territory. All of this, in itself, led to the start of the American Civil War between the Confederacy and the U.S.Fort Sumter was and to this day is a sea fort in Charleston South Carolina. It was built in 1811. During and after the secession that followed president Lincoln’s election, numerous threats were aimed at Union troops that were stationed in their forts in the south. These troops and other important members moved to Fort Sumter because it was the safest place to be at that time. According to history.net “The Lincoln administration left the question of war up to the Confederates, which would be determined by whether or not they fired on the Federal supply ship and the fort, which the Federals did not intend to give up.” For the second time the North attempted to send a supply ship down to Fort Sumter. The South wanted to block it and force it to surrender, which they did. This made the head officer at Fort Sumter, General Anderson, consider surrendering the Fort because now that the supply ship had been seized, they were sure to starve to death. They told him to wait because they were going to fire upon the Confederates very shortly. At 4:30 am the next day, it all started. This allegedly was the beginning of the American Civil war. It is evident that the biggest contributor to the outbreak of the American Civil war was the institution of Slavery itself. Had there been no slavery in America, the South would not have felt the need to separate itself from the other States. Lincoln was the trigger that was pulled, to start everything in motion, because a different President at that time, may not have pushed for the change in the same way he was determined to. So although Uncle Tom’s Cabin opened the eyes of the public and the incident at Fort Sumter was the first step, the combination of Slavery and Lincoln took America to that point in History.
