Germany in the 19th century
Billroth’s life coincided with tumultuous times in Germany. There were the revolutions of 1848, the wars of 1848 and 1864 against the Danes, the Austro-Prussian war of 1866 and the Franco-Prussian war of 1870. Billroth did his best to involve himself in the Franco-Prussian war despite being in effect an Austrian citizen. I have yet to discover whether the other upheavals had any impact on Billroth. These are matters for exploration.
