Kunigunde died from complications of the birth. Matthias Corvinus had lost his fiancee, Elisabeth of Cilli, at a young age. Matthias was eighteen, his bride thirteen.
The wedding negotiations had begun in 1458 when Catherine was nine years old.
Janus Pannonius helped teach Catherine Latin. The queen was very young, so she played little part in the politics of her husband"s two kingdoms.
She died in childbirth at the age of 14. Her child died soon after birth as well.
The event caused Matthias to lose hope of siring a legitimate heir.
Matthias"s only surviving offspring was an illegitimate son, John Corvinus, by a mistress named Barbara.
