Until the shocking murder of Empress Elisabeth in Geneva that September, royal assassinations (apart from that of Alexander II of Russia in 1881) in Europe since the end of the French Revolutionary era had been quite rare; European royalty could be fairly confident they would die of natural causes. However, from then on major royal assassinations became disturbingly frequent (1898, 1900, 1903, 1905, 1908, 1913, 1914), culminating in the horrors of the Russian Revolution two decades later. (It's perhaps worth noting that during the same era presidents of the world's two leading republics, the USA and France, were assassinated in 1865, 1881, 1894, and 1901.) So the summer of 1898 can be seen as the tail end of a relatively calm time, though Europe would enjoy sixteen more years of general peace before the real apocalypse.
For absolute pictorial consistency an 1899 version is here; by then, no thrones had changed hands but the monarchs of Denmark, Austria, and Bulgaria had all been widowed, and the Tsar had buried his beloved younger brother.
