Nine European Sovereigns at Windsor for the funeral of King Edward VII in May of 1910, four years before the war began. Standing, from left to right: King Haakon VII of Norway, Tsar Ferdinand of Bulgaria, King Manuel II of Portugal, Kaiser Wilhelm II of the German Empire, King George I of Greece and King Albert I of Belgium. Seated, from left to right: King Alfonso XIII of Spain, King-Emperor George V of the United Kingdom and King Frederick VIII of Denmark. Within the next decade, Kaiser Wilhelm II and Tsar Ferdinand's empires would engage in bloody warfare with the nations led by King Albert I and King George V. The war was also a family affair, as Kaiser Wilhelm II was a first cousin to King George V, and an uncle to King Albert I. Of the remaining monarchs pictured, over the next decade one would be assassinated (Greece), three would keep their nations neutral (Norway, Spain, and Denmark), and two would be forced out of power by revolutions.
