With the death of her brother-in-law King Jimeno in 931, Queen Toda became regent and guardian for her young son, García Sánchez I.

This led to the rebellion in Falces by a count Fortún Garcés, an "irascible man who hated Muslims", the uprising being suppressed with Cordoban arms.

The caliph sent her his Jewish physician Hasdai ibn Shaprut, who promised to cure Sancho on condition that Toda visit the city of Córdoba.

[6] Therefore, Toda, her son García Sánchez I of Pamplona and grandson Sancho I of León, nobles and clergymen arrived in Córdoba, where they were received with full honors and amid much pomp.

[4][7][8] The arrival of this Christian queen in the capital of an Islamic caliphate enhanced Abd-ar-Rahman III's prestige among his subjects,[9] and is considered a landmark in the history of medieval diplomacy.
