In the postwar period, various heads of state visited Hamburg and its City Hall — among them Emperor Haile Selassie I, the Shahanshah Mohammed Reza Pahlavi in 1955, and in 1965 Queen Elizabeth II. An emotionally moving service of remembrance was held on the market-square for the victims of the North Sea flood of 1962. Happier moments were the celebrations of Hamburger SV as German football champions, the last time though in 1983.
