Edward Channing,
A Short History of the United States for School Use
“ Many Southerners were eager to found a slave confederacy apart from the Union. Many abolitionists were eager to found a free republic in the North. Many Northerners, who loved the Union, thought that slavery should be confined to the states where it existed. They thought that slavery should not be permitted in the territories, which belonged to the people of the United States as a whole. They argued that if the territories could be kept free, the people of those territories, when they came to form state constitutions, would forbid slavery as the people of California had just done. ”
