The Eurovision Song Contest was created in 1956 to promote European integration through popular culture. The vote to determine which artist wins the competition is based on the preferences of a national jury and the public in each participating country.

from which nation came most of the points received by a given country over the past 60 years. As an example The UK got the most points from Ireland. Notably, there are some regional boundaries: Scandinavian, Balkan and former USSR countries tend to support each other almost systematically. Other solidarities come from bilateral relationships, often due to migrations, like Portuguese in France or Turks in Germany.
