Question

why did the north oppose slavery

Answer 1

By the start of the Civil War, there were a variety of different factors which caused the North to oppose slavery

Answer 2

Throughout American history, the differences between the northern and southern states have often been the cause of divisions between the two. The American Civil War was the climax of an escalating feud between the north-based Union and the south-based Confederacy, a feud which had significant basis in the different attitudes and lifestyles of each side`s respective citizens. Although the Civil War was based on more than one issue, slavery became a considerably important topic as the War went on. After numerous disputes about state and federal rights, and the election of Abraham Lincoln on an anti-slavery platform, several "cotton states" seceded from the United States, sparking what would become the Civil War. While it is certainly true that a significant portion of the North's anti-slavery conviction was based on moral principles, to argue that morality was the sole factor in the Union's abolitionist ideals would be a false generalization. In fact, many of the North's anti-slavery ideals were not based on morality, but rather political, economical, and even racist factors. The anti-slavery ideology of many northerners extended far past mere moral rationale and into reasons of self-gain. Unfortunately, this area of history has often been modified to place the North (whose ideals formed the foundation of modern America) in a better light.
