"Entry of the Gladiators" (Einzug der Gladiatoren), Op. 68, is a march composed by Czech composer Julius Fučík in 1900, originally intended as a heroic military piece. It became universally associated with circus performances after Louis-Philippe Laurendeau arranged a version in 1901 under the title "Thunder and Blazes," making it one of the most recognizable pieces in popular culture.
