Compare and contrast constitution of american and constitution of the confederacy

The American Constitution and the Constitution of the Confederancy were surprisingly similar in content, but one big difference was that the Constitution of the Confederacy respected, promoted, and defended the institution of slavery on the basis that races are unequal, while the U.S. Constitution, still lacking the Thirteenth Amendment, did not explicitely promote or defend Slavery.

everyone shares everything
