Partizan's biggest rivalry is with Red Star Belgrade. The matches between these rivals have been labeled as the Eternal derby (Serbian: Вечити дерби, Večiti derbi) or Belgrade derby. The rivalry started immediately after the creation of the two clubs. Red Star was founded for Yugoslav youth and Partizan as the football section of the Yugoslav People's Army. The rivalry is also intensified by the fact that both clubs have their stadiums situated only a few hundred metres apart. The Eternal derby is particularly noted for the passion of both supporters groups. The stands of both teams feature fireworks, coloured confetti, flags, rolls of paper, torches, smoke, drums, giant posters and choreographies, used to create visual grandeur and apply psychological pressure on the visiting teams, hence the slogan, "Welcome to Hellgrade". Some fans also use trumpets, similar to the supporters in South America. This creates for the region a typical and distinctive Balkan Brass Band atmosphere. Both sets of supporters sing passionate songs against their rivals, and the stadiums are known to bounce with the simultaneous jumping of the fans.
