Rainbow flags tend to be used as a sign of a new era, of hope, or of social change. Rainbow flags have been used in many places over the centuries: in the German Peasants' War in the 16th century, as a symbol of the Cooperative movement; as a symbol of peace, especially in Italy; to represent the Tawantin Suyu, or Inca territory, mainly in Peru and Bolivia; by some Druze communities in the Middle east; by the Jewish Autonomous Oblast; to represent the International Order of Rainbow for Girls since the early 1920s, and as a symbol of gay pride and LGBT social movements since the 1970s. In the 1990s, Archbishop Desmond Tutu and President Nelson Mandela described the newly democratic South Africa as the "rainbow nation", also alluding to its diversity and multiculturalism.
