The Union Dissolution Day, observed in Norway on 7 June (though not a public holiday), is marked in remembrance of the Norwegian parliament's 1905 declaration of dissolution of the union with Sweden, a personal union which had existed since 1814. The day is celebrated in Norway as the Independence Day and is an official flag flying day, and is observed with ordinary salute at Akershus Fortress. The Independence Day, however, has few traditions of celebration beyond that.
