Henry, Count of Tyrol and Duke of…

Henry, Count of Tyrol and Duke of Carinthia and Carniola, having in 1306 wed Anna Přemyslovna, the daughter of Wenceslaus II, had become the new brother-in-law of King Wenceslaus III of Bohemia, and had been elected King of Bohemia following the latter's murder in this same year.

Anna’s fourteen-year-old sister Elisabeth, now the only single princess in the family, is of an age to marry and so becomes one of the key players in the seizure-of-power disputes over the Kingdom of Bohemia.

The quarrels of the Bohemian throne between Henry of Bohemia and Rudolph of Habsburg had resulted in Rudolph taking Bohemia and marrying Elisabeth Richeza of Poland (Elisabeth's stepmother).

Elisabeth had gone to live in Prague Castle with her brother's widow, Viola Elisabeth of Cieszyn.

However, Rudolph's death had caused the throne to return in 1307 to her brother-in-law and sister, who had wanted Elisabeth to marry the lord of Bergova (Otto of Löbdaburg) for political reasons.

Upon Elisabeth’s refusal, an opposition group is made against Henry and Anne, with Elisabeth as the figurehead.

John, Count of Luxembourg and the eldest son of German king Henry VII and his wife Margaret of Brabant, is in 1310 elected as King of Bohemia and so one of the seven prince-electors of the Holy Roman Empire.

The fourteen-year-old John, French by education but deeply involved in the politics of Germany, is forced to invade Bohemia with the backing of the Bohemian nobility and his father.

Henry and Anna retire to Carinthia; Elisabeth marries John at Speyer in September 1310.
