"De Wilhelmus" (pronounced [də vilˈhælmus]; Luxembourgish for "The Wilhelmus") is the grand ducal anthem of Luxembourg. Lyrics for it were written in 1919 by Luxembourgish writer Nik Welter, although they are not often used in official performances. The anthem is performed whenever a member of the grand ducal family enters or leaves an official ceremony, while the national anthem, "Ons Heemecht", is performed at national celebrations. It takes its name from the Dutch national anthem, but it has always since then been written with the Luxembourgish neutral article De as opposed to its namesake, written without or with the Dutch neutral article Het.
