Beethovens Variations and Fugue for Piano Op. 35 are based on a theme from 3rd Symphony. This Symphony, called the Eroica, is a revolutionary work he intended to dedicate to Napoleon, the French Revolutionary who fought for the people's rights. In his piano sonata “Les Adieux” implies a programmatic nature. The French attack on Vienna, led by Napoléon Bonaparte in 1809, forced Beethoven's patron, Archduke Rudolph, to leave the city. The sonata is one of Beethoven's most challenging sonatas because of the mature emotions that must be conveyed throughout it.
The two piano pieces by Franz Liszt are demonstrating also his concern for social political issues. He dedicated Chapelle de Guillaume Tell to the depiction of the Swiss struggle for liberation from the Habsburgian. Liszt chooses a motto from Friedrich Schiller as caption, "All for one - one for all." His composition Lyon was composed under the impression of the silk-weaver-revolt of Lyon.
