The song was composed by Rezső Seress while living in Paris, in an attempt to become established as a songwriter in late 1932.
 The original musical composition was a piano melody in C-minor, with the lyrics being sung over it.
 Seress wrote the song at the time of the Great Depression and increasing fascist influence in the writer's native Hungary, although sources differ as to the degree to which his song was motivated by personal melancholy rather than concerns about the future of the world.
 The basis of Seress's lyrics is a reproach to the injustices of man, with a prayer to God to have mercy on the modern world and the people who perpetrate evil.
 There are some suggestions that the words of ""Vége a világnak"" were in fact not written until World War II itself and not copyrighted until 1946.

Prosper-Didier Deshayes (mid 18th century – 1815) was an opera composer and dancer who lived and worked in France.
 In 1764 he was a balletmaster at the Comédie-Française.
 By 1774 he had become an assistant ("adjoint") at the Paris Opéra.
 His first opera "Le Faux serment ou La Matrone de Gonesse", a "comédie mêlée d'ariettes" in two acts, was first performed on 31 December 1785 at the Théâtre des Beaujolais in Paris and became a popular success.
 He went on to have another 18 works performed at various venues in Paris, but only two, "La faut serment" and "Zélie, ou Le mari à deux femmes", a 3-act "drame" first performed at the Salle Louvois on 29 October 1791, were ever published as musical scores.
 He also participated in the collaborative Revolutionary opera "Le congrès des rois", a 3-act "comédie mêlée d'ariettes", which combined music written by Deshayes and 11 other composers and was first performed by the Opéra-Comique at the Salle Favart on 26 February 1794.

Johann Sebastian Bach composed the church cantata Brich dem Hungrigen dein Brot ("Break with hungry men thy bread" or "Give the hungry ones thy bread"), BWV 39 , in Leipzig and first performed on 23 June 1726, the first Sunday after Trinity that year.
 Three years earlier, on the first Sunday after Trinity in 1723, Bach had taken office as Thomaskantor and started his first cycle of cantatas for Sundays and Feast Days in the liturgical year.
 On the first Sunday after Trinity in 1724, he began his second cycle, consisting of chorale cantatas.
 The cantata "Brich dem Hungrigen dein Brot " is regarded as part of Bach's third cantata cycle which was written sporadically between 1725 and 1727.
There are 52 chorale cantatas by Johann Sebastian Bach surviving in at least one complete version.
 Around 40 of these were composed during his second year as Thomaskantor in Leipzig, which started after Trinity Sunday 4 June 1724, and form the backbone of his chorale cantata cycle.
 The eldest known cantata by Bach, an early version of "Christ lag in Todes Banden", BWV 4, presumably written in 1707, was a chorale cantata.
 The last chorale cantata he wrote in his second year in Leipzig was "Wie schön leuchtet der Morgenstern", BWV 1, first performed on Palm Sunday, 25 March 1725.
 In the ten years after that he wrote at least a dozen further chorale cantatas and other cantatas that were added to his chorale cantata cycle.
