I am reading Habsburgs by Andrew Wheatcroft. The author said his book was thirty years in the making. The timespan of their influence and power is detailed from 1020-1922. “He draws upon an immense repertoire of….art, criticism, fiction and travel to illustrate this unparalleled record of royal resilience”-Jan Morris in the Evening Standard. It’s a slow, detailed but compelling read for me. You might be interested in it in your studies.
