As Rosas aged and his health declined, the question of who would succeed him became a growing concern among his supporters. His wife Encarnación had died in October 1838 after a long illness. Although devastated by his loss, Rosas exploited her death to raise support for his regime. Not long after, at the age of 47, he began an affair with his fifteen-year-old maid, María Eugenia Castro, with whom he had five illegitimate children. From his marriage to Encarnación, Rosas had two children: Juan Bautista Pedro and Manuela Robustiana. Rosas established a hereditary dictatorship, naming the children from his marriage as his successors, stating that "[t]hey are both worthy children of my beloved Encarnación, and if, God willing, I die, then you will find that they are capable of succeeding me." It is unknown whether Rosas was a closet monarchist. Later during his exile, Rosas would declare that Princess Alice of the United Kingdom would be the ideal ruler for his country. Nonetheless, in public he stated that his regime was republican in nature.
