After 1864 the day became more established when the first children's parade was launched in Christiania, at first consisting only of boys. This initiative was taken by Bjørnstjerne Bjørnson, although Wergeland made the first known children's parade at Eidsvoll around 1820. It was only in 1899 that girls were allowed to join in the parade for the first time. In 1905, the union with Sweden was dissolved and Prince Carl of Denmark was chosen to be King of an independent Norway, under the name Haakon VII. Obviously, this ended any Swedish concern for the activities of the National Day.
