Ultras are a type of association football fans who are renowned for their fanatical support. The term originated in Italy, but is used worldwide to describe predominantly organised fans of association football teams. The behavioural tendency of ultras groups includes their use of flares (primarily in tifo choreography), vocal support in large groups and the displaying of banners at football stadiums, all of which are designed to create an atmosphere which encourages their own team and intimidates the opposing players and their supporters. The frequent use of elaborate displays in stadiums is also common.
