RTL and the Centre for Audiovisual Content (CNA) have provided us with another glimpse into the past, this time providing images from former National Day celebrations.

The date of Luxembourg's National Day has changed various times over the years. In the 19th century, the tradition to celebrate it on the birthday of the Grand Duchy's sovereign was established: 24 April for Grand Duke Guillaume I, 6 December for Grand Duke Guillaume II, and 17 June for Grand Duke Guillaume III.

When Grand Duke Adolphe succeeded to the throne in 1890, the celebratory day was set to 24 July, then to 22 April under Grand Duke Guillaume IV, and 14 June under Grand Duchess Marie-Adélaïde. Under Grand Duchess Charlotte, National Day was celebrated on 23 January.

Finally, on 23 December 1961, a Grand Ducal decree decided that festivities would be fixed to 23 June, a tradition which both Grand Duke Jean and Grand Duke Henri have followed since.
