Which of these individuals was not a member of the republican party?

Assuming that this is referring to the same list of options that was posted before with this question, the correct response would be "Franklin D. Roosevelt" since he was one of the most progressive Democrats of his time. 

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.
