Editing John III of Sweden (section)

===In captivity===

When the summons was not obeyed by John, he was sentenced in June 1563 by the [[riksdag of the Estates|Estates]] assembled in Stockholm as guilty of treason, deprived of life, property and hereditary rights to the kingdom. To carry out the sentence, a considerable army was equipped. John, who was unprepared for battle, was locked up in [[Turku Castle]], defended himself there for a few weeks with 1200 men and then surrendered on 12 August 1563, in exchange for the promise of a princely prison (the [[Siege of Åbo (1563)|Siege of Åbo]]).<ref name=su1>{{Cite web|url=https://runeberg.org/svupps/2-14/0753.html|title=Project Runeberg, Svensk uppslagsbok, Andra upplagan.

When John and his wife were brought to Gripsholm on a ship, they passed through ''Söderport'', where the executions of 30 of John's supporters took place. John remained a prisoner for more than four years. However, his imprisonment was relatively light, especially compared to what Erik would later experience; among other things, the couple was able to receive a large shipment of books. John, who was bookish, also spent much of his time studying and conversing with his wife. Their three children were born in captivity, in 1564 Elizabeth, called Isabella, who died at the age of two, in 1566 Sigismund and in May 1568 Anna.{{sfn|Harrison|Eriksson|2010|p=413}}
