This is a court gift from the later Kaiser Wilhelm I of Prussia on the occasion of the wedding of Prince Philipp of Belgium (1837-1905), the so-called Count of Flanders and third-born son of Leopold I, King of Belgium, to Maria Louise Alexandra Karoline of Hohenzollern-Sigmaringen (1845-1912) in the Roman Catholic St. Hedwig's Cathedral in Berlin. This marriage was arranged by Queen Victoria of England. Maria Louise, daughter of Princess Josephine of Baden and Prince Karl Anton of Hohenzollern-Sigmaringen, thereby became Countess of Flanders. According to the inscription, this vase was presented to Countess Claire d'Yve, who was the lady-in-waiting to Marie Louise of Hohenzollern-Sigmaringen. Such magnificent vases with the portrait of the king were given on behalf of Wilhelm I of Prussia for important occasions or as tokens of appreciation as personal gifts. At the time of the gift of this magnificent vase in 1867, Wilhelm I was still King of Prussia until he was crowned German Emperor in 1871.
