In club football,'Ultras' refer to a long-standing group of institutional fans renowned for their fanatical support. They are membership-based organizations that aim to create an atmosphere which intimidates opposing teams/fans through the use of verbal support, flares, banners etc. In some cases, Ultras have been associated with violent altercations with rival fans during games. While Ultras are not directly associated with the football club, they organize meetings with the staff/coaches and have reserved seats in stadiums. Many Ultras also engage in political activism across the spectrum. Examples include Indonesian club Persebaya's Ultras (the Bonek) campaigning against FIFA corruption, Turkish club Beşiktaş’ “Çarşı”protesting against president Erdogan's repression and Inter Milan's Curva Nord supporting right-wing Italian politics.
