I have read numerous times that the Dred Scott Decision led to the Civil War in the United States, but I have been unable to find sources to support this. It seems that the Dred Scott Decision chiefly led to other contributing factors such as the split in the Democratic Party and the rise of Lincoln.
I was wondering how, therefore, the decision actually acted as a catalyst to the Civil War, and if there were any books or reputable sources that provide a clear story.
