Historical Background

Belgium became independent from the Netherlands in 1830; it was occupied by Germany during World Wars I and II. The country prospered as a modern, technologically advanced European state and member of NATO and the EU. In recent years, longstanding tensions between the Dutch-speaking Flemish of the north and the French-speaking Walloons of the south have led to constitutional amendments granting these regions formal recognition and autonomy.
