Which cities were least affected by ideas from foreign lands? explain.

The cities worth large trade routes were affected the most, this is because they had foreign traders that came through and each brought their own ideas from their homes. The cities that were least affected were the ones  that are far from the trade routes because they didn't get the influence from the foreign trade.

Hope this helps :)
