Adolph Markstein was the Chancellor of the German Empire in the early 1960s. When Mexican President Vincent Mercator announced his Offensive of the Dove on November 20, 1962, Chancellor Markstein dismissed it as "a propaganda play and nothing more." Markstein also refused to attend Mercator's Geneva Conference in the summer of 1963 because no agenda had been agreed upon.
Sobel does not indicate whether Markstein is a member of the Deutschland Party or the Democratic Party.
Markstein is a continuing character in For All Nails, where he is assumed to be the head of the Deutschland Party.
