Johann Baptist Strauss II (1825 – 1899), also known as Johann Strauss Jr., the Younger or the Son (German: Johann Strauß Sohn), was an Austrian composer of light music, particularly dance music and operettas as well as a violinist. He composed over 500 waltzes, polkas, quadrilles, and other types of dance music, as well as several operettas and a ballet. In his lifetime, he was known as "The Waltz King", and was largely responsible for the popularity of the waltz in Vienna during the 19th century. Some of Johann Strauss's most famous works include "The Blue Danube", "Kaiser-Walzer" (Emperor Waltz), "Tales from the Vienna Woods", "Frühlingsstimmen", and the "Tritsch-Tratsch-Polka". Among his operettas, Die Fledermaus and Der Zigeunerbaron are the best known. He was the son of Johann Strauss I and his first wife Maria Anna Streim. Two younger brothers, Josef and Eduard Strauss, also became composers of light music, although they were never as well known as their brother.

Johann Strauss I's influence over the local entertainment establishments meant that many of them were wary of offering the younger Strauss a contract for fear of angering the father. Strauss Jr. was able to persuade Dommayer's Casino in Hietzing, a suburb of Vienna, to allow him to perform. The elder Strauss, in anger at his son's disobedience, and at that of the proprietor, refused to ever play again at Dommayer's Casino,[10] which had been the site of many of his earlier triumphs. Strauss made his debut at Dommayer's in October 1844, where he performed some of his first works, such as the waltzes "Sinngedichte", Op. 1 and "Gunstwerber", Op. 4 and the polka "Herzenslust", Op. 3. Critics and the press were unanimous in their praise of Strauss's music. A critic for Der Wanderer commented that "Strauss's name will be worthily continued in his son; children and children's children can look forward to the future, and three-quarter time will find a strong footing in him."

"Radetzky March" (Op. 228), is a march composed by Johann Strauss Sr. and dedicated to Field Marshal Joseph Radetzky von Radetz. First performed on 31 August 1848 in Vienna, it soon became popular among regimented marching soldiers. It has been noted that its tone is more celebratory than martial; Strauss was commissioned to write the piece to commemorate Radetzky's victory at the Battle of Custoza. Strauss had already used the theme in his Jubel-Quadrille, Op. 130; the upbeat bears a considerable resemblance to the second theme from the Allegro in Joseph Haydn's Symphony No. 100 composed in 1794. The rhythmic pattern—three anapaests, one iamb—has since then been popularised by numerous parody versions.

For the trio, Strauss used an older folk melody called Alter Tanz aus Wien or Tinerl-Lied (Tinerl was a contemporary Viennese songstress) which was originally in 3/4 time. When Radetzky came back to Vienna after winning the battle of Custoza (1848), his soldiers were singing the then-popular song. Allegedly Strauss heard this singing and incorporated the melody, converted to 2/4 time, into the Radetzky March. Along with the Blue Danube waltz by Johann Strauss Jr., the piece became an unofficial Austrian national anthem. In 1932 Joseph Roth published his novel Radetzky March, chronicling the decline and fall of the Austro-Hungarian Empire. Today, the theme is used in numerous promotional jingles and at major sporting events, in particular at football matches of the Austrian national team. Since 1896, the Radetzky has been the official presentation march of the Chilean Army's Military School of the Liberator Bernardo O'Higgins and the Paraguayan Army's Marshall Francisco Solano López Military Academy. The 1st The Queen's Dragoon Guards of the United Kingdom adopted the Radetzky March as its regimental quick march.

When it was first played in front of Austrian officers, they spontaneously clapped and stamped their feet when they heard the chorus. This tradition, with quiet rhythmic clapping on the first iteration of the melody, followed by thunderous clapping on the second, is often observed when the march is played in classical music venues in an orchestral version prepared by Leopold Weninger (1879–1940).
