Frankfurt and the river [[Rhine]] tributary [[Main (river)|Main]] acquired transnational economic importance in the [[Middle Ages]]. In 1337 the [[Louis IV, Holy Roman Emperor|Holy Roman Emperor Louis IV of Bavaria]] issued a diploma privilege so that any other city was not allowed to establish a market or trade fair if this could harm the Frankfurt Trade Fair in any way. This imperial backing allowed Frankfurt to retain the commanding importance of the Frankfurt Trade Fair for centuries. In the Middle Ages the full range of manufactured and semi-processed commodities were trade at Frankfurt Fairs.<ref>{{cite book|title=Textiles and the Medieval Economy: Production, Trade, and Consumption of Textiles, 8th–16th Centuries|editor1=Angela Ling Huang|editor2=Carsten Jahnke|publisher=Oxbow Books|isbn=9781782976509|date=2014|page=217}}</ref>
