 Unhappy with the rule of Henry of Carinthia, and wary of the claims of the Habsburgs who had some legitimate claim on the crown, they convinced Henry to marry his son John I, Count of Luxemburg to Elizabeth, the daughter of Wenceslas II, and so establish a claim to the Bohemian crown.In July 1310 he engineered the removal of Henry of Carinthia.On 15 August 1309, Henry VII announced his intention to travel to Rome, having sent his ambassadors to Italy to prepare for his arrival, and so consequently expected his troops to be ready to travel by 1 October 1310.
