A supporters' group or supporters' club is an independent fan club or campaign group in sport, mostly association football.
Supporters' groups in continental Europe are generally known as ultras, which derives from the Latin word ultrā,[1] meaning beyond in English, with the implication that their enthusiasm is 'beyond' the normal. In the Anglosphere, these groups are generally known as "supporters' groups". Most groups in the United States, Canada, United Kingdom, and Australia call themselves "supporters' groups"; however, some do self-identify as ultras, particularly in communities with large Spanish, French, or Italian speaking populations. In Mexico, they are called porras, while in South America they are called either hinchada (plural of hincha, a Spanish word that was first used in Uruguay to refer to a single fan or supporter) or, exclusively in Brazil, torcida (plural of torcedor, which means 'supporter' in Portuguese) and fanaticada (plural of 'fan' in Portuguese). All of these terms are most commonly used to refer to the whole crowd of a team in the stadium and not just the groups within those crowds that lead the chants and display of choreographies and flags.
These groups in particular are barras bravas in Argentina and torcidas organizadas in Brazil (where there are also barras bravas, but are less in comparison). Both (but especially barras bravas) are organised supporters' groups that are not only focused on supporting their team and intimidating rivals, but also on antagonizing opposing fans, or defending (themselves and the rest of their club's supporters) from police repression or attacks by rival groups.
Supporters' groups and ultras are renowned for their fanatical vocal support in large groups, defiance of the authorities, and the display of banners at stadiums, which are used to create an atmosphere to intimidate opposing players and supporters, as well as cheering on their own team.[2]
