Laws requiring teaching of the Holocaust
A number of countries maintain laws that require the presentation of information concerning actions of the government of Germany regarding Jews in its territory during the period of that government's control by the National Socialist (Nazi) German Worker's Party from 1933 to 1945, commonly referred to as the Holocaust. In the United States, laws of this kind are maintained by individual states and typically specify curriculum content and the ages of the pupils to which various portions of the curricula are to be presented.
