   1900.ethnia.org is an essay which goal is to try to find the countries, territories, governments, administrative divisions and main international organizations that have existed during the 20th century. The first version of the website dates back from 1996 and had been put online under ethnia.org in 1999. The current version is from 2009 and now allows to search for an entity for any day of the 20th century.
   Current depth of investigation: . [rose: country completed at level 2 (province, county, ...), red: level 3 (district, ...), white: level 1 only (region, federated State, ...)]
