is a German Easter hymn, with a text mostly by Cyriakus Spangenberg, who added to an older first stanza, and a 1544 tune by the Bohemian Brethren.
The first stanza of "Wir wollen alle fröhlich sein" was written in the 14th century in Medingen Abbey, a nuns' monastery.
The following four stanzas were added by Cyriakus Spangenberg in Eisleben.
The melody appears first in a Bohemian monastery in Hohenfurt, another sources says "Böhmische Brüder 1544" (Bohemian Brethren 1544).
[1][2] It has appeared in German-language hymnals, including in the Protestant hymnal Evangelisches Gesangbuch as EG 100, and in the Catholic hymnal Gotteslob as GL 326.
