In 1885 the editors of the liberal Utrecht newspaper Utrechtsch Provinciaal en Stedelijk Dagblad set out to build a national holiday that could hold a divided country together. They chose the birthday of five-year-old Princess Wilhelmina, 31 August, rather than that of her father King Willem III, who was too contested to serve as a unifying symbol. The first Prinsessedag was held on 31 August 1885, and the observance became Koninginnedag once Wilhelmina took the throne.
A princess becomes a queen
Willem III died in November 1890, and his daughter became queen under her mother's regency. The festival changed its name with her. The first Koninginnedag was held in 1891, still on her birthday in late August.
