During the Austrian-Hungarian attack on Serbian territory in 1914 and 1915, obituaries for Belgrade and the Kingdom of Serbia were published. There are many examples of these from World War One. Written in German, they were intended as a morale booster for the Austrian public.
Like any other obituary, these include the names of the deceased, and the mourners. The text at the beginning is standard: With great pain and sorrow... Changes were made only to the names of the deceased, and in this case the mourners are given as Allied countries and their rulers.
