Belgians make new rules in Rwanda!

In 1918, The League of Nations nominated Belgium to reign over Rwanda. Shortly after Belgium assumed control of Rwanda, however, they started to organize a census and mandate that every person be issued an identity card, classifying them as either Tutsi, Hutu, or Twa and separated these groups. Later, in December of 1948, the United Nations passed a resolution which defined the actions Belgium had taken as a genocide and declared it a crime under international law.
