The Year of the Three Emperors, or the Year of the Three Kaisers, (German: Dreikaiserjahr) refers to the year 1888 during the German Empire in German history.[1][2][3][4] The year is important because two German Emperors, or Kaisers, died. This meant that there were three emperors in a year..[1] The three emperors who ruled Germany during this year were Wilhelm I, Frederick III and Wilhelm II. The mnemonic “drei Achten, drei Kaiser” (English: "three eights, three emperors") is still used today in Germany to remember which year it was.[5]
