Political factions in Sweden The Stockholm Bloodbath was a consequence of conflict between Swedish pro-unionists (in favour of the
Kalmar Union, then dominated by Denmark) and anti-unionists (supporters of Swedish independence), and also between the anti-unionists and the Danish
aristocracy, which in other aspects was opposed to King Christian. The anti-unionist party was headed by
Sten Sture the Younger, and the pro-unionist party by the Archbishop
Gustavus Trolle.
Military interventions of King Christian King Christian, who had already taken measures to isolate Sweden politically, intervened to help Archbishop Trolle, who was under
siege in his
fortress at
Stäket. However, he was defeated by Sture and his peasant soldiers at
Vedila, and forced to return to Denmark. A second attempt to bring Sweden back under his control in 1518 was also countered by Sture's victory at
Brännkyrka. Eventually, a third attempt made in 1520 with a large army of
French,
German and
Scottish mercenaries proved successful. In May, the Danish fleet, led by King Christian, arrived and
Stockholm was attacked by land and sea. Lady Kristina resisted for four months longer, and in the beginning of autumn Kristina's forces began winning. The inhabitants of Stockholm had a large supply of food and fared relatively well. Christian realized that his stockpile was dwindling and that it would doom his army to maintain the siege throughout the winter. With the help of
Bishop Mattias, Hemming Gadh and other Swedes of high stature, Christian sent a proposal for retreat that was very advantageous for the Swedes. During a meeting on what is thought to be Beckholmen, outside of
Djurgården, Christian swore that all acts against him would be forgotten, and gave pardon to several named persons (including
Gustav Vasa, who had escaped from Denmark, where he had been held hostage). Lady Kristina would be given Hörningsholm and all Mörkön as a
fief, and was also promised
Tavastehus (Hämeenlinna) in
Finland. When this had been written down on paper, the mayor of the city delivered the keys to the city on
Södermalm and Christian held his grand entry. Shortly after, he sailed back to Denmark, to return in October for his coronation. ==Massacre==
