Well, when the Roman Empire was around there really weren't any European countries. It was more tribal areas. As for the Renaissance and the Industrial Revolution, they were both, for the most part, beneficial occurrences in history. World War II on the other hand on the other hand had a horrific effect on the countries of Europe.
