The establishment took place following a decree signed by General Mihail Lascăr, High Commander of the Romanian Royal Army.

In the same year, CCA, coached by Ilie Savu, became the first Romanian team to participate in a tournament in England, where it achieved noteworthy results against the likes of Luton Town, Arsenal, Sheffield Wednesday and Wolverhampton Wanderers.

Under the leadership of coaches Emerich Jenei and Anghel Iordănescu, Steaua had an impressive Championship run in the 1984–85 season, which it won after a six-year break.

[13] The Romanian Revolution led the country towards a free open market and, subsequently, several players of the 1980s team left for other clubs in the West.

After a short pull-back, a quick recovery followed and Steaua managed a six consecutive championship streak between 1992–93 and 1997–98 to equalize the 1920s performance of Chinezul Timișoara[14] and also three more cups in 1995–96, 1996–97 and 1998–99.

At international level, the club also managed to reach the UEFA Champions League group stage three years in a row between 1994–95 and 1996–97.

[17] Subsequently, even though the club managed to win five national championships and to qualify for the UEFA Champions League four times, it became increasingly associated with Becali's controversial character, infamous for his homophobia,[18] xenophobia, misogyny, racism,[19] tax evasion[20] and even imprisonments.

[22] The club which had acted as Steaua throughout this time was summoned to change their name and logo;[23] presently, they are officially called SC FC FCSB SA and continue to play in Liga I.

Funded from privately owned CSA Steaua finances,[26] the team's objective is to promote every year to the higher league, until it reaches Liga I, a timeline which is to coincide with the opening of the new Stadionul Ghencea.

Due to the high profile of the participants, the match was moved to the Arena Națională and attracted a crowd of 36,277, setting a lower-league national record; Rapid București won 3–1 to consolidate their position at the top of the table, with Steaua five points behind in second place.

During its first season, 1947–48, Steaua wore yellow and red striped shirts with blue shorts, to symbolize Romania's tricolour flag.

Following the Romanian Revolution, the Army decided to break all links to the defunct communist regime, so, in 1991, CSA Steaua had a last change of crest with an eagle also present on the Ministry of Defence coat of arms and also on Romania's.

The stadium was built through order of the Ministry of National Defence inside a former military base and was long used by CSA Steaua.

While ultra groups stopped attending matches around the time of the Court's demand that FCSB doesn't have the rights to be Steaua, regular spectators (citizens) continued their presence at Arena Națională matches and now form the majority of the FCSB support, mostly at important European fixtures but also with Universitatea Craiova, CFR Cluj and Dinamo Bucharest.

[citation needed] Ever since the Court's decision in 2014, Peluza Sud has fully adopted the reopened football team of Steaua București and represents a constant presence for the Liga IV matches.

[32] During the 2017–18 season, while playing in the 4th Romanian division, Steaua's home match against Rapid achieved a national record, with an audience of 36.277 spectators.

[34] With 39 titles combined (Steaua – 21; Dinamo – 18), the two sides have won 31 more than the third-most successful Liga I club, Venus București.

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.

As Steaua is the most popular club in Romania, there are, besides Bucharest, several cities counting a great majority of red and blue supporters among football lovers.

Widely speaking, these cities are predominant in the Eastern half of the country, particularly in the regions of Moldavia, Greater Wallachia and Northern Dobruja.

Cities such as Suceava, Piatra Neamț, Bacău, Galați (inside Moldavia), Constanța (Northern Dobruja), Buzău, Brăila, Târgoviște, Călărași (Greater Wallachia), Râmnicu Vâlcea, Târgu Jiu (Oltenia), Brașov, Oradea, Sibiu, Târgu Mureș or Petroșani (Transylvania) enjoy a great majority of Steaua fans which are often well-received even by fans of the local teams.
