Jerusalem: The Biography

* The Jewish communities of the world were ruled by the two hereditary gaons of the Jerusalem Academy and the Babylonian/Iraqi Academy, whose seat was in Baghdad. The Karaites spread throughout the Jewish world, building up large communities from the Crimea to Lithuania that survived up to the Holocaust, when most of them were annihilated. This led to one of the strangest anomalies of the Nazi repression: in the Crimea, some Karaites were of Turkic rather than Semitic origin, so the Nazis actually ordered the protection of this Jewish sect.
