I'm to writing an essay about, as the topic title says, the Roman influences on the germanic tribes, in particularily the ones living on the border regions of the Empire (around 100 bc - 200 ad) in what are now the Netherlands and Germany. I need information on how the roman expansions and trades influences the culture and way of life in the germanic tribes that lived there, and what happened afterwards with those influences (did they disappear?). It has to be a high quality essay so I'll need sources as well.
