==Variations==
An important set of variations on the melody of "Wilhelmus van Nassouwe" is that by the blind [[carillon]]-player [[Jacob van Eyck]] in his mid-17th century collection of variations ''Der Fluyten Lust-hof''.<ref name=eyck>{{cite book|editor1-last=Michel|editor1-first=Winfried|editor2=Hermien Teske|title=Jacob van Eyck (ca. 1590–1657): Der Fluyten Lust-hof|year=1984|publisher=Amadeus Verlag – Bernhard Päuler|location=Winterthur}}</ref>

The [[royal anthem]] of [[Luxembourg]] (called "[[De Wilhelmus]]") is a variation on the "Wilhelmus". The melody was first used in Luxembourg (at the time in [[personal union]] with the [[Kingdom of the United Netherlands]]) on the occasion of the visit of the Dutch King and [[Grand Duke of Luxembourg]] William III in 1883. Later, the anthem was played for [[Adolphe, Grand Duke of Luxembourg|Grand Duke Adolph of Luxembourg]] along with [[Ons Heemecht|their national anthem]]. The melody is similar, but not identical to that of the "Wilhelmus"; it has been in official use since 1919.

The song „[[Wenn alle untreu werden]]“ ("When All Become Unfaithful"), better known as „Das Treuelied“, written by the poet [[Max von Schenkendorf]], used exactly the same melody as the "Wilhelmus".{{Citation needed|date=October 2022|reason=The melody of "Wenn alle untreu werden" comes from the French song ''Pour aller à la chasse faut être matineux'' and not from the "Wilhelmus".}} After [[World War I]], this song became popular among [[German nationalism|German nationalist]] groups. It became one of the most popular songs of the [[Schutzstaffel|SS]], together with the „[[Horst-Wessel-Lied]]“.

The melody is also used in the [[Swedish language|Swedish]] [[folk song]] "{{ill|Ack, Göta konungarike|sv}}" ("Alas, [[Götaland|Gothic Kingdom]]"), written in 1626, which deals with the liberation struggle of [[Sweden]] under [[Gustav Vasa]] during the 16th century.
