the answer can be trade if you are focusing on the Italian renaissance

Explanation:

during the renaissance, specifiaclly the Italian renaissance, trade was a very popular mean of trading goods and culture. This is seen specifically in Florence Italy where many other countries traded with these Italians and the city thrived with great wealth as a result of trade. Trade can be seen through the silk roads as people from Asia could then trade with those in Europe.
