What is "krymchaks"

The Krymchaks ( Krymchak: sg. - , pl. - ) are Jewish ethno-religious communities of Crimea derived from Turkic-speaking adherents of Orthodox Judaism. They have historically lived in close proximity to the Turkic Karaites who follow Karaite Judaism.

At first krymchak was a Russian descriptive used to differentiate them from their Ashkenazi Jewish coreligionists, as well as other Jewish communities in the former Russian Empire such as the Georgian Jews, but in the second half of the 19th century this name was adopted by the Krymchaks themselves. Before this their self-designation was "Срель балалары" (Srel balalary) - literally "Children of Israel". The Crimean Tatars referred to them as zuluflı çufutlar ("Jews with pe'ot") to distinguish them from the Karaites, who were called zulufsız çufutlar ("Jews without pe'ot").
