Latgale
"Latgale has been exposed to the widest variety of cultures historically. Before the Second World War, for instance, most of the townsfolk were Jewish, and we were part of the Polish-Lithuanian Commonwealth, also Russian influences. And even those divided into the Old Believers and the newer Russians – people who came more recently. So you have to be more open and more tolerant, and this creates this acceptance and maybe makes people feel more open compared to the rest of the country."

"Not many people know that actually, but actually after the Second World War, when we had the resistance – the forest brothers – carrying on. Within Latvia, the total number was – historians put it – around 20,000. Of those, 10,000 or half were in Latgale."
