Although a couple of wars were fought on the European continent during the 19th century, an uneasy peace was mostly maintained across the continent for most of the 19th century after Napoleon. Despite this ostensible peace, the Europeans were steadily conducting arms races against each other. With Europe anticipating a potential war, all that was missing was a conflagration. That would start in 1908, when Austria-Hungary annexed Bosnia-Herzegovina in the Balkan Peninsula, drawing it into dispute with Russia. Moreover, this upset neighboring Serbia.
