For centuries much of Europe was in the hands of the very peculiar Habsburg family. An unstable mixture of wizards, obsessives, melancholics, bores, musicians and warriors, they saw off – through luck, guile and sheer mulishness – any number of rivals, until finally packing up in 1918. From their principal lairs along the Danube they ruled most of Central Europe and Germany and interfered everywhere – indeed the history of Europe hardly makes sense without them.
