 Afonso died from epilepsy at the age of two, devastating the emperor. The following year, Pedro and Teresa Cristina had another son, Pedro Afonso, but he too died in infancy. After the loss of his second son, doubts grew in Pedro II's mind that the imperial system could be viable. He still had an heir in his daughter Isabel, but he was unconvinced that a female would prove to be a suitable successor. He showed less concern about the effects his policies had on the monarchy, provided his daughter Isabel with no training for her role as potential empress, and failed to cultivate her acceptance within the country's political class. Pedro II's lack of interest in protecting the imperial system ultimately led to its downfall.
