Will fill in some points on France and Germany from memory
Industrial unrest in France (1968 in particular I seem to recall), I believe started in 19th century.
Germany- Personally I believe that industrialisation helped lead to WWI. The arms race which started in the 1890's was part of this.
Political pressure to colonise other countries.
Can't remember any others right now, but I echo the idea that google would be likely to help.
