The Lesser National Coat of Arms is widely used within the national administration, while the Greater National Coat of Arms is used mainly by the monarch and the Royal Family, the Riksdag and Government and the diplomatic service.
The flag
The flag was for a long time the symbol of the King of Sweden, his token of sovereignty. The essence of it, and the real symbol of the nation, was the yellow cross.
The origins of the cross flags of the Nordic countries are to be found in the banners of the cross which medieval Christian princes carried on their crusades against the infidel in the Holy Land. The banner, carried on a pole, indicated the ruler's dignity. Mostly it would be a red standard with a white or silver cross. Denmark and Switzerland alone have retained this red banner as their national flags. Oldest among the Nordic flags is the Dannebrog (supposedly from "Danish breech" or "cloth"), the crusading banner of the King of Denmark, which set the pattern for the other Nordic countries.
Sweden's is the second oldest of the Nordic flags and is believed to have come about in the mid-15th century, during the reign of Karl Knutsson Bonde. His seal in 1449 had a four-quartered blue shield divided by a golden cross, and he is assumed to have carried a banner with the same tinctures (colours). Probably the Swedish flag came into being as an emblem of resistance during the battles of the Kalmar Union, when Karl Knutsson Bonde adopted a Dannebrog-like banner charged with the cross but with the tinctures - yellow and blue - of the Swedish national coat of arms.
The ducal arms of Johan III are described in 1557 as charged with blue-and-yellow flags of the cross. When, in 1569, as King of Sweden, he issues instructions for the peace talks with Denmark at Knäred, he is at pains to stress the importance of the yellow or golden cross. For ages past this had been used in the arms of the Swedish kingdom, and so Johan III wanted it always to be displayed in flags and standards.
From the death of Gustav Vasa in 1560, the cross flag appears as the foremost symbol of the Swedish nation: a swallow-tailed Swedish flag in which the national coat of arms, with the inescutcheon of the reigning dynasty, has been superimposed on the centre of the cross.
Triple-tailed naval flags are recorded from the reign of Gustavus Adolphus. During the 1620s the flag lost its ancient quality of Royal insignia and instead came to symbolise the nation, the Kingdom of Sweden.
The Three Crowns national coat of arms has quite a different origin, partly rooted in religious ideas which were widespread in Europe at the time, more exactly in the rapidly growing cult of the Three Wise Men (alias the Three Kings) as patron saints, heraldically represented by their three crowns. The Three Kings were held in great veneration by the Northerners, large numbers of whom made the pilgrimage to their grave in Cologne. In Sweden the attribute of the Three Kings first appears in the seal of King Magnus Ladulås during the 1270s, but probably it was not until the reign of King Magnus Eriksson in the 1330s that the Three Crowns were made to symbolise king and kingdom. A few decades later, by the time of Albrekt of Mecklenburg, the Three Crowns were already commonly accepted as the principal emblem of Sweden, and they have remained so ever since.
The sword of state, purchased by Gustav Vasa, is the oldest of the monarchic regalia. The other items - the (regal) crown, the sceptre, the orb and the key - date from the coronation of his eldest son, Erik XIV, in 1561. These are exquisite specimens of the goldsmith's art, embellished with pearls, precious stones and enamel of various colours. They were made in Stockholm. The Fleming Cornelis ver Weiden made the crown to a new, modern design, with two crossed arches over the cap and a small globe, surmounted by a cross, over the centre. This was Sweden's first regal crown of the closed variety, and the idea purportedly came from England.
The regalia have a symbolism all of their own, noted down from the coronation of Erik XIV. The crown is an emblem of regal honour and dignity. The sceptre stands for the secular power of the King, and the orb shows that God has set him to rule over a great and Christian kingdom. The key denotes the King's power of excluding evil, harbouring good and opening to the needy, while the sword, finally, alludes to the King's duty of valiantly and vigorously protecting good and punishing evil.
The queenly crown is nearly 200 years younger than the regal one. Made of silver and set with 695 diamonds, it was commissioned for Lovisa Ulrika in 1751. The earlier queenly crown, of gold decorated with diamonds and rubies, was made in 1620 for Queen Maria Eleonora, the consort of Gustavus Adolphus (Gustav II Adolf). King Adolf Fredrik was so fond of it that he wore it himself, thereby setting a precedent for his son, Gustav III, and subsequent monarchs.
