Nyköping Banquet

Present-day appearance of Nyköping Castle, in which the Dukes were starved to death.

The Nyköping Banquet (Swedish: Nyköpings gästabud) was King Birger of Sweden's Christmas celebration 11 December 1317 at Nyköping Castle in Sweden. Among the guests were his two brothers Duke Valdemar and Duke Eric, who later that night were imprisoned and have been assumed to have subsequently starved to death in the dungeon of Nyköping Castle.

Prelude

The dukes Valdemar and Eric, brothers of King Birger, had earlier staged a coup against the king (Håtuna games). After the intervention of the Danish and Norwegian kings, a settlement was reached in 1310 and Sweden was divided among the brothers into three sovereign states.

Treacherous arrests

Seven years later, the dukes Valdemar and Eric were invited as a sign of reconciliation to celebrate Christmas with King Birger and Queen Martha at Nyköping Castle. The banquet was held on the night between 10 and 11 December 1317. The dukes' retinues were lodged not in the castle, but in the town of Nyköping, the pretext being lack of space. After both dukes had retired to bed, the king's drost Brunke (Johan von Brunkow) arrived with a company of crossbowmen and handcuffed them. The following morning, the dukes' retinues were also apprehended.

According to the Eric Chronicles, King Birger himself was present, reminding the dukes of the Håtuna Games:

Mynnes jder nakot aff hatwna leek? Fulgörla mynnes han mik

(Remember ye aught of the Håtuna Games? I remember them clearly)

Imprisonment

The dukes were imprisoned in the castle's dungeon. They knew that no mercy would be forthcoming from Birger so they had their wills drawn up after five weeks. These documents, dated 18 January 1318, survive today. Soon thereafter, both dukes died in the dungeon, according to tradition by drawn-out starvation. According to legend, King Birger threw the keys to the dungeon into the Nyköping river. A large medieval key was indeed found during the 19th century near the castle.

King Birger, however, had misjudged the political situation in the country. A rebellion broke out in 1318 against his rule, and he was forced to flee to Gotland, whence he soon had to continue his flight to Denmark.

Aftermath

Following a year of regency by his mother Duchess Ingeborg, the three-year-old son of Duke Eric, Magnus (IV), was elected King in 1319 at the Stone of Mora in Uppland. King Birger's son Magnus resisted forces that tried to take Castle Nyköping but was defeated and fled with the senechal Brunke. They lost a sea action and were captured and executed in Stockholm in 1320. Brunke was executed on a sandy ridge which has since been known as the Brunkeberg Esker; the heir apparent was decapitated on the Isle of the Holy Spirit where the Riksdag Building is today. The deposed king Birger died in 1321 in exile in Denmark.

Thus, of the royal family, there remained only the old queen mother Helvig of Holstein, (widow of Magnus Ladulås), the exiled Queen Martha, the young king Magnus IV (son of the late Duke Eric), his sister Euphemia, their mother Ingeborg and her cousin Duchess Ingeborg of Öland (widow of Duke Valdemar).
