Julius Ernest Wilhelm Fučík was a Czech composer and conductor of military bands. He became a prolific composer, with over 400 marches, polkas, and waltzes to his name. As most of his works were for military bands, he is sometimes known as the "Bohemian Sousa".

A march, as a musical genre, is a piece of music with a strong regular rhythm which in origin was expressly written for marching to and most frequently performed by a military band. In mood, marches range from the moving death march in Wagner's Götterdämmerung to the brisk military marches of John Philip Sousa and the martial hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op. 91a by Jean Sibelius, and in the Dead March in Handel's Saul.
