Duke of Uppland

Duke of Uppland is a substantive title from the Kingdom of Sweden given by a king to a son or grandson. In earlier centuries duchies in Sweden conferred a ruling position to their prince-duke, sometimes nearly on par with the power held by the king himself; since 1772 dukedoms have been granted in title only. Uppland, meaning "Upper Lands", is one of the provinces of Sweden.
