Episode 11: The Luck of the Habsburgs

From humble roots in Switzerland and Swabia, the Habsburg dynasty endured for 900 years, its survival due in part to genetic good fortune. As historian Martyn Rady tells Paul and Miranda, the Habsburgs gambled big on marital matches that would expand and consolidate their power across Europe - and more often than not, they hit the jackpot. Their territories came to include colonies in Africa, the Americas and Asia, further reinforcing their wealth and status. But in the 17th century, even this most adept of dynasties failed to control the forces that unleashed brutal war in central Europe.

Martyn Rady's book 'The Habsburgs: the Rise and Fall of a World Power' is published by Penguin.

'1666 and All That' is presented by Miranda Malins and Paul Lay. The producer is Hugh Costello. Original music is by George Taylor. The episode was mixed by Sam Gunn.
