Analysis of information sources in references of the Wikipedia article "Yahudi Ortodoks" in Malay language version.
Until the French Revolution, all Jews would probably have been regarded as Orthodox, but in modem times Orthodoxy has developed a self-conscious ideology that, for some, distinguishes it from historical or traditional Judaism.
As Timothy Snyder points out, although Auschwitz is located in Poland, actually very few Polish or Soviet Jews were killed there, and thus the largest victim groups — religiously orthodox Jews from Eastern Europe — are excluded from the most famous symbol of the Holocaust.
An entirely accurate estimate of how many Orthodox Jews were killed is impossible, but they were clearly the majority, somewhere between 50-70 percent.
