The Netherlands: Why Belgium?

Misha Glenny ends his Netherlandish travels in Brussels, and asks why does Belgium exist. With details on the brief Kingdom of the Netherlands - a union with the Dutch in the north - and the reason why the British went to war with Germany in 1914. There is a faultline in Europe, running from the North Sea to the Alps, and this is one reason Belgium exists.
With contributions from Gita Deneckere of Ghent University; Simon Winder, who's at work on a new book called Lotharingia; and Paul Arblaster, author of A History of the Low Countries.
