Augusta Victoria of Schleswig-Holstein also sponsored the Augusta Victoria complex on the Mount of Olives in Jerusalem, a church and hospice inaugurated in 1910 that later became a hospital. After Germany's defeat and the fall of the monarchy in November 1918, she joined Wilhelm in exile in the Netherlands. When Wilhelm became emperor in June 1888, she became German empress and queen of Prussia. Deeply religious and conservative, she promoted the building of Protestant churches in Berlin and supported charities and nursing. She was buried at the Antique Temple in Potsdam. Augusta Victoria of Schleswig-Holstein had already suffered a stroke in 1918, which greatly impaired her health. The press speculated late that year that she "would hardly live to see the new year." In July 1920, her youngest son Prince Joachim died by suicide, about which Wilhelm commented, "That rascal has done that to us and especially to his mother as well!" The shock of exile and abdication, with the breakdown of Joachim's marriage and his subsequent suicide, proved too much for Augusta's health. She died on 11 April 1921 at Huis Doorn at Doorn in the Netherlands, from a severe heart attack. Some of her last reported words were, "I must not die; I cannot leave the Kaiser alone."
