King Alfonso XIII visited Las Hurdes in 1922 in order to display the concern of the crown. Gregorio Marañón accompanied the young king as guide. The king and his retinue lived in military tents planted near the town of Casares de las Hurdes. During the king's visit a famous awkward incident took place: A local village chief, concerned that the king was drinking only black coffee (a consequence of the king's aides distrusting the quality of the local milk owing to unsanitary conditions in the area) served the king a small jug of milk saying "Your Majesty rest assured that this milk is totally trustworthy", which turned out to be milk from his wife who had recently given birth. The king became aware of this fact only "after" having had his "café con leche".
