Anyway, I'm listening to Nieves Concostrina doing one of her little history slots on the radio. She's talking about the expulsion of the Jews from Spain in 1492 with her usual mix of dry humour and anticlerical sarcasm. It's pretty obvious from her description that the two kingdoms that would later go on to be the bulk of present-day Spain—Castile and Aragon—were in a sort of racial and ideological turmoil. The interactions between Muslims, Christians and Jews were labyrinthine and Machiavellian, to say the least. And that's before the Inquisition got its teeth in and began to undermine the power and influence of any socio-religious group that wasn't staunchly Catholic. Remembering that 1492 is a pivotal year: it's when the last Muslim stronghold finally falls in the peninsula, over 700 years after the initial invasion, and it's the year that the world changes forever when Spanish money sent Colón (Columbus) off to find the spice route—and he inadvertently bumped into the continent which would later give us Donald Trump.
Suddenly, in the radio story, there was a little aside about Villena the town and the Marquis named for it. The Marquis of Villena is, like one of those top dog British lords, named for a county, that pepper so many Shakespeare historical plays - "and thee Essex, get thee to Northumberland". Now Juan Pacheco, 1st Duke of Escalona, 1st Marquis of Villena—was an important man at the time of Isabel and Fernando, the Catholic Monarchs. Despite wearing tights, he had castles and land all over the place. He was rich and he was powerful. Later, one of his descendants, Juan Manuel—another Marquis of Villena—would go on to found the Real Academia Española, the organisation that publishes the Spanish dictionary of reference and tries to maintain order within a language spoken worldwide.
When Enrique (Henry if you prefer) IV of Castile died in 1474, there were two claimants to the throne of Castile (by this time Castile was probably about 75% of what's now Spain). The struggle was between supporters of Joanna "la Beltraneja," Henry IV's (probable) daughter, and his half-sister Isabel. Our Marquis, Juan Pacheco, originally sided with Joanna.
Back in Villena, one of the Marquis's relations—Pedro Pacheco—was the warden of the castle there. He gathered together a bunch of people who had allegiance to the Marquis. The story goes that many of these people had converted from Islam or Judaism to Christianity to hang on to their wealth. They were not well liked by old established Christian families—to keep sides clear I'll call the people in the castle the New Christians. Meanwhile, the general population of Villena, the people in the town, or the Old Christians—had decided to side with Isabel and against Joanna and the Marquis.
As things came to a head, the New Christians planned to attack the Old Christians as they went to Sunday Mass. The plot was discovered as was the agreed signal that would tell the New Christians when to attack—the ringing of a bell five times. When the Old Christians heard that bell they knew what was coming. They were ready and armed to the teeth. There was a pitched battle in the streets of the Villena and nearly all the New Christians were slaughtered. Somehow Juan Pacheco managed to wheedle out of having backed the wrong side when Isabel finally came to power and hung on to his wealth and lands.
And to remember that fateful day the Santa María Church in Villena is unique in Spain in sounding the bell five times for Mass. Apparently it's usually three.
Oh, and the other Marquis of Villena I mentioned—the dictionary-writing one—also initially picked the wrong side when the Spanish crown was up for grabs again during the War of Succession (1701–1714). He supported the Austrian claim rather than the, finally victorious, French one. Like his ancestor though, he somehow sidled out of that disgrace.
As usual with these legends there is a lot of contradictory information. I tried to pick my way through it but do be aware that this account may be complete rubbish.
