I'm looking for some info on the impact the 6th century Byzantine reconquest of Italy and the coast of Spain had not just on those areas but Western Europe in general at that time, namely the rest of Spain, Francia and Britain and Ireland, . The effects can range really into the proceeding century or so. This can include military, architecture, culture, trade, society, state, religion and anything really. Archeological findings are very much appreciated, and if you could perhaps provide evidence that would also be great.

Any books/articles and possibly website recommendations would also be greatly appreciated. Thanks guys.
