Vienna was the capital of the Habsburg dynasty and home to the Holy Roman Emperors. From here, they dominated middle Europe for nearly 1,000 years. In this series, historian Simon Sebag Montefiore describes how the Habsburgs transformed Vienna into a multi-national city of music, culture and ideas. Napoleon, Hitler, Mozart, Strauss, Freud, Stalin and Klimt all played their part.
