Duke of Södermanland

Duke of Södermanland is a title that has been created in the Kingdom of Sweden several times. It is unanimously given by the Queen to one of her sons or grandsons. In earlier centuries duchies in Sweden conferred a ruling position to their prince-duke, sometimes nearly on par with the power held by the queen herself; since 1772 dukedoms have been granted in title only. Södermanland, meaning "South man land", is one of the provinces of Sweden, named for its position in reference to Lake Mälaren.
