Sancho of Aragon (c. 1400 – March 1416) was an Aragonese infante (royal prince) and the grand master of the Order of Alcántara from 1409.
Ferdinand envisaged his children as a powerful bloc of supporters and future co-rulers and made sure they received an education commensurate with their foreseen role.
[2] Ferdinand acquiesced in the appointment of Benedict's nephew, Pedro de Luna, as archbishop in 1407 and in return Benedict granted a dispensation allowing the child Sancho to be elected to succeed Fernando Rodríguez de Villalobos as master of Alcántara in 1408.
[1] Sancho was formally received as grand master in the convent of San Pable de Valladolid on 23 January 1409.
He then left the court to return to Castile and take up his role as master of Alcántara, but he died en route at Medina del Campo.
