Christina of Saxony (25 December 1461 – 8 December 1521), was Queen consort of Denmark, Norway, and Sweden. She was born a granddaughter of Frederick the Gentle of Saxony, and daughter of Ernest, Elector of Saxony and Elisabeth of Bavaria. She was the grandmother of Christina of Denmark through her son Christian II. Christina was engaged to John, King of Denmark, Norway and Sweden, in 1477. The year after, she traveled from Saxony to Warnemunde, where she was met by a Danish retinue who brought her Copenhagen Castle, where she was married to John on 6 September 1478.In 1481, she became queen of Denmark. She was however not crowned until 1483, when John had become king of Norway also. On 18 May 1483, she and John were crowned king and queen of Denmark and Norway in the Frue Kirke in Copenhagen. During the first twenty years of her marriage, there is not much information about Christina, and she seems to have lived a life devoted to her family. In 1497, John was elected king of Sweden. Two years later, Christina followed him to Sweden, and on 4 February 1499, they were crowned king and queen of Sweden in Uppsala. She accompanied John on his second visit to Sweden in 1500, and his third in January 1501. During the 1501 visit, John entered into his love affair with one of her ladies-in-waiting, Edel Jernskjæg, which attracted a scandal and caused a de facto termination of her marriage. When the War of Deposition against King Hans and Dano-Swedish War (1501–1512) took place later that same year, John left Sweden for Denmark in August 1501 in the company of Edel Jernskjæg. He left Christina in charge of the garrison of the Castle of Tre Kronor in Stockholm as regent and as moral support for his followers. From September 1501 until 6 May 1502, Queen Christina was besieged by the Swedish rebels. This was one of the hardest sieges known during the Kalmar Union, during which a garrison of 1000 men was reduced to 70 out of plague and starvation.
