History of the Jews in Cologne archbishop vacant, but Charles IV was not near enough to take action. On 23–24 August the relative security of Jews in Cologne came to an end. The Jews, who had already faced slaughter in the surrounding territories, were now also killed in Cologne itself. The actual outcome of the pogrom is not well known.
