Ultras are a type of football fan renowned for ultra-fanatical support, occasionally to the point of violence and hateful chants and slogans. They are predominantly followers of football teams, typically in South America, Europe, and north Africa.
The behavioural tendency of ultras groups includes the 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 opposing players and supporters. The use of elaborate displays in stadiums often is common, as well.
The actions of ultras groups are occasionally extreme and may be influenced by political ideologies or views on racism. In some instances, this goes to the point where the passionate and loyal support of one's team becomes secondary to the theoretical ideology of the ultras phenomenon. In recent decades, the culture has become a focal point for the movement against the commercialization of sports and football in particular.

Roma Ultras (Lazio Rome fans) occupy the Curva Sud side of the Olympico Stadium. The Eternal City has been dubbed "Stab City" by the British media after the high number of Stabbings that have taken place against Engish fans traveling there. The Roma Ultras are a well organised outfit and date back to the 1960's. During this time there was a number of small factions dotted all around the Stadio Olympico. In 1987 the group began to break up and new groups began to form. Roma now has many different ultras groups.
