Gustav Eriksson Trolle (September 1488 – 1535) was Archbishop of Uppsala, Sweden, in two sessions, during the turbulent Reformation events.
He was the son of Eric Arvidsson Trolle, a former regent of Sweden during the era of the Kalmar Union. After returning from studies abroad, in Cologne and Rome, he was in 1513 elected vicar in Linköping. One year later he became Archbishop of Uppsala. In 1515 he got into an argument with the Swedish regent Sten Sture the Younger, who spread the rumour that he was allied with the King Christian II of Denmark. True or not, it resulted in Trolle being removed from his office and put under siege in the archbishop's mansion Almarestäket at lake Mälaren. In the winter of 1517, Almarestäket was demolished by orders from the Swedish government.
The Danish threat grew stronger, and Trolle was among those who spoke in favour of the Danish King. In 1520, Christian II of Denmark entered Sweden, and Trolle was rewarded by being reappointed Archbishop of Uppsala. He crowned Christian King of Sweden on 4 November, 1520. This, and subsequent events, supports the notion of the two having made a deal previous to Christian's conquest of Sweden.
Stockholm Bloodbath
Gustav Trolle presented a list of antagonists who had caused him to suffer and who had ordered the demolition of Almarestäket. King Christian gathered several people (some sources say 100, other say 20), and had them executed at the so-called Bloodbath of Stockholm on 10 November, 1520. The details and death toll are uncertain, for Christian himself wanted the public execution to have as strong effect as possible, and later, King Gustav I of Sweden is likely to have boosted the figures to support his Danish War.
