Swedish heraldry
Swedish heraldry follows the German-Nordic heraldic tradition, characterized by the use of multiple helmets and crests which are treated as inseparable from the shield, its repetition of colours and charges between the shield and the crest, and its scant use of heraldic furs. Swedish and Finnish heraldry have a shared history prior to the Diet of Porvoo in 1809; these, together with Danish heraldry, were heavily influenced by German heraldry.
