Agnes' mother, Elisabeth Richeza, subsequently married Rudolf I of Bohemia, son of Albert I of Germany on 16 October 1306.[3] Rudolph was chosen to be King of Bohemia by part of Czech nobility and Elisabeth remained queen consort for a short time. Rudolph died of dysentery on 4 July 1307,[4] after becoming ill during the siege of the fortress of one of the revolting noblemen, Bavor III of Strakonice. In his last will, Rudolph acknowledged Elizabeth Richeza's dowry towns and entailed her a huge amount of money in silver talents.[5]
Shortly after the wedding and, with the consent of Elisabeth, Henry I went with his troops to her dowry town, Hradec Králové in North Bohemia, where he organized expeditions to support rebels against King John of Bohemia.[5]
Agnes had only one pregnancy which ended in a miscarriage, in the first trimester when she rode with her horse over a hill. This accident kept her in bed for many months. Agnes died in 1337, only two years after her mother and nine years before her husband. [citation needed]
