The Argument That the Civil War Began Primarily as a Southern

The argument that the Civil War began primarily as a southern fight to defend liberty and the right of self-government is unsatisfactory because:

A) the Union already claimed to be fighting to defend liberty and self-government.
B) southerners never claimed to be concerned with liberty and self-government.
C) the South established a monarchy after secession.
D) the Confederacy envisioned a dictatorship as the ideal government.
E) it ignores slavery,the actual reason that southern leaders used in 1860-1861 to justify secession and war.
