Joanna of Castile vs John Balliol

After the death of her husband Philip I, Joanna of Castile became the nominal queen of Castile. However, her father Ferdinand II of Aragon and later her son Charles I of Spain assumed regency, citing her mental instability. Joanna was confined to the castle of Tordesillas for the rest of her life.

After the death of her husband Philip I, Joanna refused to remarry, despite pressure from her father Ferdinand II and other nobles. Her refusal was interpreted as a sign of mental instability, but it also reflected her deep attachment to Philip and her desire to maintain her independence.

Joanna of Castile was confined to the Royal Palace of Tordesillas by order of her father Ferdinand II, who declared her unfit to rule. She remained imprisoned there for 46 years, isolated from political affairs, while her son Charles I governed Castile in her name.

John Balliol, as a claimant, was party to the Treaty of Birgham which arranged the marriage of Margaret, Maid of Norway to Edward II. The treaty promised Scottish independence, but it was never fully implemented after Margaret's death.

John Balliol was selected as King of Scots by Edward I of England after the Great Cause arbitration. Edward I oversaw the selection process and Balliol swore fealty to him, effectively making Scotland a vassal state.

John Balliol's Scottish army was decisively defeated by English forces under John de Warenne at Dunbar. The defeat led to Balliol's abdication and Edward I's conquest of Scotland, with the Stone of Destiny taken to Westminster.

John Balliol abdicated the Scottish throne after his defeat at Dunbar. He was stripped of his royal regalia and imprisoned in the Tower of London, later being exiled to France. His reign ended with Scotland under English occupation.
