Does this cartoon fit into the narrative about southern succession in 1860? what would southerners (and union) think about?

When the South Succeeded from the Union, they had left the Union completely.
The person cutting the branch, or the southern states, off of the tree, or the Union, represents the South succeeding from the Union.
So this cartoon would fit into the narrative about Southern Succession
The southerners would feel that this is a good representation about what happened, but the northerners would feel that the southerners had never truly succeeded in the beginning, until later.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
