In the mid-nineteenth century, what inspired so many middle-class protestants to participate in reform movements?

They were inspired by their belief in a social gospel that every person could be saved through repentance, revivals and conversion. And the establishment of many reform movements were designed to get rid of the evils of society before the Second coming of Christ could happen.

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.

Ibelieve the answer is 1756.
