The Spanish Inquisition - It Was the Tetris All Over Again

Jewish people did have to practice crypto Judaism for a very long time which was concealing. A lot of Jews had fled to Portugal from Spain when they thought the Spanish inquisition would just stick to its namesake. They wrote Hebrew prayers but in Catholic prayer books and so people wouldn't know they would observe their Black Pass over and Yom Capur on slightly different days. There was this amazing story that one community was found in Portugal in a little place called Belmonte in 1917 which had kept its faith completely secret since the 1490s. It's been crypto Jewish since then.
