Armata Ultra (AU), the first Ultras group from Bucharest (and second in Romania after Politehnica Timișoara's Commando Viola Ultra Curva Sud), were set. The group quickly reached an impressive number of members, but, in 2001, they dissolved due to internal problems. Steaua's supporters then divided into several groups, some of them being located at the Peluza Nord ("North End" – Titan Boys, Nucleo, Insurgenții 1998, Skins 1996, Combat, Tornado 47, Armata 47 Vest), while some other ones taking their place at the Peluza Sud ("South End" – Vacarm, Glas, E.R.A., Hunters, Outlaws, Shadows, Roosters, T.K., Tinerii Sudiști). Several important groups such as Stil Ostil, Ultras, Banda Ultra and South Boys retired from attending Steaua's matches due to the club's constant abuses towards them and, mainly, to the current ownership of Steaua. More recently, as of 2006, the supporters have formed their own official association, called AISS (Asociația Independentă a Suporterilor Steliști – "Steaua Supporters' Independent Association"). AISS was formed as a legal entity with its stated goals of "protecting the interests and image of Steaua supporters", as well as "identifying and promoting the club's perennial values". Steaua's Peluza Nord and Peluza Sud fan groups no longer support the current team, as a sign of protest. The Peluza Sud have instead started to attend the matches of CSA Steaua. However, an online poll conducted by Sport.ro in 2017 has shown that of the 120,000 voters, 95% consider FCSB to hold the real Steaua identity. Rivalries Steaua's most important rivalry is the one against Dinamo București. Eternul derby ("The Eternal Derby") has been the leading Romanian football encounter since 1948, as Steaua and Dinamo are the two most successful football teams in the country. There have been more than 150 matches played so far between Steaua and Dinamo in the Romanian League, the Romanian Cup and also the Romanian Supercup. With 44 titles combined (Steaua – 26; Dinamo – 18), the two sides have won 36 more than the third-most successful Liga I club, Venus București. It is also a match between the former clubs of the Romanian Army (Steaua) and the Ministry of Internal Affairs (Dinamo). Several clashes between different factions of supporters have often occurred and still occur inside and outside the stadium. The heyday was reached before a match kick-off in 1997, when Dinamo's fans set a sector of Stadionul Ghencea's Peluza Sud, where they were assigned, on fire.
