Wiphala

The Wiphala (Quechua pronunciation: [wɪˈpʰɐlɐ]) is a square emblem, commonly used as a flag, representing some native peoples of all the Andes that include today's Bolivia, Peru, Ecuador and parts of Argentina, Chile and Colombia.

The suyu wiphalas are composed of a 7-by-7 square patchwork in seven colours, arranged diagonally. The precise configuration depends on the particular suyu represented by the emblem. The colour of the longest diagonal line (seven squares) determines which of the four suyus (regions) the flag represents: white for Qullasuyu, yellow for Kuntisuyu, red for Chinchaysuyu, and green for Antisuyu. There is also an alternate pattern for the Wiphala for Antinsuyu. Additionally a Wiphala also exists for Tupac Katari and the Tupac Katari Guerrilla Army.

Article 6, section II of the new Bolivian constitution establishes the Wiphala as the dual flag of Bolivia along with the red, yellow, and green banner.

In modern times the Wiphala has been confused with a rainbow flag which is wrongly associated with the Tawantinsuyu. There is debate as to whether there was an Inca or Tawantisuyu flag. There are 16th and 17th-century chronicles and references that support the idea of a banner attributable to the Inca. However, it represented the Inca himself, not the empire. Also its origins are from symbols and mural designs found in several civilizations of the Andes with thousands of years of history.
