L'Encobert
The Hidden (Catalan: L'Encobert, Spanish: El Encubierto, "The Hidden/Shrouded [One]") (d. 1522) was a mysterious and charismatic leader of the remnants of the rebels in the last stages of the Revolt of the Brotherhoods in Aragon. Also called "The Hidden King" (Catalan: El Rei Encobert, Spanish: El Rey Encubierto), he claimed to be a prince hidden for his own safety now showing himself by divine command to save Spain from ruin. The Hidden unified the rebels for a short period, inspiring messianic fervor among his followers. He led them on hit-and-run raids against the royal government, uncooperative nobles, and Muslim peasants (mudéjars). The Hidden was killed in Burjassot on May 18, 1522, and the rebellion soon collapsed afterward. His true name and lineage are unknown.
Problems of historiography
Little is known conclusively about The Hidden. Even the exact nature of claims about him are disputed, as it is nearly impossible to tell how much truth is to the government-approved unfavorable stories of him that predominated after the fact. Some influential versions of the tale were written by authors likely more interested in a gripping story rather than historical accuracy. Many of the claims are wholly contradictory. As such, it is difficult to tell whether particular elements in The Hidden's legend come from fact, claims The Hidden made directly himself, rumors spread by The Hidden's supporters, or stories spread by the government.
