Vers l'avenir ("Towards the future"), less commonly known by its Dutch title Naar wijd en zijd, is a Belgian patriotic song which was also the national anthem of the Congo Free State. Upon the annexation of the Congo Free State as a colony of Belgium, this anthem was replaced with La Brabançonne, the national anthem of Belgium. Vers l'avenir's lyrics were written by Gentil Theodoor Antheunis (1840-1907). It was also adopted as the anthem of the Rexist Party, a far-right political movement founded in 1930 by Léon Degrelle.
