Gustav I, born Gustav Eriksson of the Vasa noble family and later known as Gustav Vasa (12 May 1496 – 29 September 1560), was King of Sweden from 1523 until his death in 1560, previously self-recognised Protector of the Realm ("Riksföreståndare") from 1521, during the ongoing Swedish War of Liberation against King Christian II of Denmark, Norway and Sweden.
 Initially of low standing, Gustav rose to lead the rebel movement following the Stockholm Bloodbath, in which his father perished.
 Gustav's election as King on 6 June 1523 and his triumphant entry into Stockholm eleven days later meant the end of Medieval Sweden's elective monarchy and the Kalmar Union, and the birth of a hereditary monarchy under the House of Vasa and its successors, including the current House of Bernadotte.
Didrik Slagheck (died 24 January 1522) was a Danish archbishop, military commander during the Swedish War of Liberation, and often pointed out as an active participant in the Stockholm Bloodbath.
Nydala Abbey (Swedish: "Nydala kloster" ) was a Cistercian monastery in the province of Småland, Sweden, near the lake Rusken.
 Although the abbey ceased to operate in the 16th century, its church was renovated and converted into a Protestant church during the 17th century and is still in use.
 The church belongs to the Church of Sweden and is part of the Diocese of Växjö.
Claus Bille (ca. 1490 – 4 January 1558 at Lyngsgård, Scania) was a Danish statesman.
 He was a major estate owner, knight (the highest rank of Danish nobility), fief lord of Båhus Castle and a member of both the Norwegian and the Danish Councils of the Realm.
 He was an important participant in the Stockholm Bloodbath, when he together with Søren Norby arrested the Swedish nobility.
 He was a first cousin of Eske Bille, and the Bille family became the most politically powerful noble family of Denmark during his lifetime.
King Christian II (Swedish: "Kung Kristian II" ), Op.
 27, is incidental music by Jean Sibelius for the Scandinavian historical play of the same name, written by his friend Adolf Paul.
 The original play deals with the love of King Christian II, ruler of Denmark, Sweden and Norway, for a Dutch girl, Dyvecke, a commoner.
 Sibelius composed in 1898 seven movements.
 He conducted the first performance of the first four parts the Swedish Theatre in Helsinki on 24 February 1898.
 In the following summer, he composed three more movements, "Nocturne", "Serenade" and "Ballad".
 The Nocturne was an interlude between the first act and the second.
 The position of the serenade changed.
 The ballad is a dramatic piece about the 1520 bloodbath which the king ordered in Stockholm.
 This movement shows already traits of the later First Symphony.
 The stage music consists of the following numbers:
Nydala Abbey Bloodbath (Swedish: "Blodbadet i Nydala kloster") in Nydala Abbey, Sweden, on 2 February 1521 was the execution of the abbot and several monks at Nydala Abbey performed by the Danish army on the orders of Christian II of Denmark during their way back to Denmark from the Stockholm Bloodbath during the Swedish War of Liberation.
