Here's a fun read regarding some of the myths regarding the Civil War. As we know, some argue that it was all about states' rights. But the author differs:
South Carolina was further upset that New York no longer allowed "slavery transit." In the past, if Charleston gentry wanted to spend August in the Hamptons, they could bring their cook along. No longer -- and South Carolina's delegates were outraged. In addition, they objected that New England states let black men vote and tolerated abolitionist societies. According to South Carolina, states should not have the right to let their citizens assemble and speak freely when what they said threatened slavery.
Other seceding states echoed South Carolina. "Our position is thoroughly identified with the institution of slavery -- the greatest material interest of the world," proclaimed Mississippi in its own secession declaration, passed Jan. 9, 1861. "Its labor supplies the product which constitutes by far the largest and most important portions of the commerce of the earth. . . . A blow at slavery is a blow at commerce and civilization."
The South's opposition to states' rights is not surprising. Until the Civil War, Southern presidents and lawmakers had dominated the federal government. The people in power in Washington always oppose states' rights. Doing so preserves their own.
Apparently states rights only mattered if a state supported slavery, not if it opposed it.
