How did merchants reawaken interest in classical culture?

The merchants started trading works of art and books and similar things with foreigners and getting them to Europe. This was important because many works of Roman or Greek origin were lost in Europe but were preserved in Arabian libraries since Arabs collected and translated anything they could find during the Golden Age of Islam. Merchants traded with them and reignited interest in classical culture again.

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.
