Page "Joanna of Castile" Paragraph 12

Ferdinand's remarriage merely strengthened support for Philip and Joanna in Castile, and in late 1505, the pair decided to travel to Castile.

Leaving Flanders on 10 January 1506, their ships were wrecked on the English coast and the couple were guests of Henry, Prince of Wales, later Henry VIII and Joanna's sister Catherine of Aragon at Windsor Castle.

They weren't able to leave until 21 April by which time civil war was looming in Castile.

Philip apparently considered landing in Andalusia and summoning the nobles to take up arms against Ferdinand in Aragon.

Instead, he and Joanna landed at La Coruña on 26 April, whereupon the Castilian nobility abandoned Ferdinand en masse.

Ferdinand met Philip at Villafáfila on 20 June 1506 and handed over the government of Castile to his " most beloved children ", promising to retire to Aragon.

Philip and Ferdinand then signed a second treaty, agreeing that Joanna's mental instability made her incapable of ruling and promising to exclude her from government.

Ferdinand then proceeded to repudiate the agreement the same afternoon, declaring that Joanna should never be deprived of her rights as Queen Proprietress of Castile.

A fortnight later, having come to no fresh agreement with Philip and thus effectively retaining his right to interfere if he considered his daughter's rights to have been infringed upon, he abandoned Castile for Aragon, leaving Philip to govern in Joanna's stead.
