The Federal government at the time had duties on any thing exported from this country. The two biggest exports were tobacco and cotton. The north was a net importer. It was where the term the Southerners call the “O Grab Me Tax” came from. Check your history.
I did. And I know of nothing that shows the U.S. government taxed exports. Only imports. And most of those were delivered to the North. So perhaps you can help us out and point us to your source?
No they didn't. The duty was only on imports.
What ever Lost Cause literature you have been reading has lied to you.
