From The Broken Road: From the Iron Gates to Mount Athos, by Patrick Leigh Fermor (Journey Across Europe Book 3, NYRB Classics, 2014), Kindle pp. 149-151:
These hostile feelings were much more deeply rooted in the north, where the Jewish population had increased from about two thousand families to close on a million in a hundred and thirty years, most of them in flight from the appalling conditions in Poland and the Russian Pale, until in several large Moldavian towns, including Yassy, the Moldavian capital, they now outnumbered the Rumanian inhabitants and monopolized the commerce of the province. Small wonder that this indigestible explosion of people caused dismay, resentment and hostility among the inhabitants; there was nothing comparable here to the harmonious and long established position of the polished and much less numerous Sephardim of the Ottoman world; small wonder, too, that the Jews, denied full citizenship and with nearly every route to advancement or honour denied to them, should expand and excel in the only field that was not barred by prejudice. The remote principality in which they suddenly began to proliferate had no middle class; rural society knew nothing between the mediaeval feudalism of landowners – the great and the lesser boyars, many of whom seldom set foot on their accumulations of acres – and a vast and callously exploited peasantry. There was no urban middle class, and, in Moldavia especially, as the country expanded, the Jewish population became a semi-alien bourgeoisie of middlemen and retailers.
Everyone reluctantly admitted that the Jews were honest in their dealings, however ruthless, and faithful to their agreements. I also noticed that nearly everyone, however ill-disposed in general, had one Jewish friend who ‘was not like the others’, an array of exemptions that must have added up to an imposing total. It was only on later travels in Moldavia and Bukovina that I got to know, talk to and even make friends with Jews not isolated in a Gentile majority. Lack of any need to conform to alien ways had left their way of life absolutely intact: the long black kaftans, broad-brimmed black velvet hats, skullcaps, black, red and blond beards, corkscrew side-whiskers (like those of my host and his son in the woods of the Banat), and a Yiddish largely unalloyed by Rumanian, but embedded with Polish and Russian words as well as the Hebrew studied by the rabbis and divinity students.
