From A Time of Gifts: On Foot to Constantinople: From the Hook of Holland to the Middle Danube, by Patrick Leigh Fermor (Journey Across Europe Book 1, NYRB Classics, 2011), Kindle pp. 295-296:
We had hardly said good-bye when a spectacled young man on a bike overtook me and dismounted, with a greeting in Slovak—‘Dobar den,’ I think, instead of ‘jo nápot kivánok’—and asked where I was going. He fell in step beside me [and we conversed in German]. He was a schoolmaster and he enlarged on the past sorrows of Slovakia. It is true that the local villages are Hungarian, but further north they are pure Slovak as far as the Polish border. They had been under the Magyars for a thousand years and always treated as an inferior race, and when any Slovak rose in the world he was promptly seduced into the lesser Magyar nobility—with the result that all local leadership evaporated. Slovak children used to be taken away from their parents and brought up as Magyars. Even when they were fighting the Austrians in defence of their nationality and language, the Hungarians were busy oppressing and Magyarizing their own Slovak subjects. The schoolmaster didn’t seem to like the Czechs much either, though this involved a different kind of resentment. The Czechs, it seems, regard the Slovaks as irredeemable bumpkins, while in Slovak eyes, the Czechs are bossy, petit bourgeois bureaucrats who take unfair advantage of their closeness to the government in Prague. The schoolmaster himself was from northern Slovakia, where—partly thanks to the Hussites, partly to the general spread of the Reformation in east Europe—much of the population is Protestant. I hadn’t realized this. It was touch and go in the Dark Ages whether the Slavs of the North became Catholic or Orthodox. Under the proselytizing influence of SS. Cyril and Methodius—the Byzantine missionaries who invented the Cyrillic script and translated the sacred writings into Old Slavonic—it could easily have been the latter. When I asked why it hadn’t, he laughed and said: “The damned Magyars came!” The link was severed, and the Czechs and Slovaks stuck to Rome and the West.
When he reached his turning he asked me to stay in his village, but I had to press on. He pedalled away with a wave. A nice man.
