The video explores the complex reasons behind the North's involvement in the Civil War, initially sparked by Abraham Lincoln's election in 1860. While many believe the North fought to abolish slavery, it wasn't until 1863 that slavery became a central issue with the Emancipation Proclamation. Initially, many Northerners fought to preserve the Union and believed in a strong federal government. Some historians suggest moral motives, while others point to economic interests in the South's resources. Misconceptions about these motives persist today.
