Qırmızı Qəsəbə (Gyrmyzy Gasaba, [ɡɯɾmɯˈzɯ ɡæsæˈbæ]), translated as "Red Town" (Russian: Красная Слобода, Krasnaya Sloboda; Hebrew: העיר האדומה‎, ha-'Ir ha-'Adumá), is a village and municipality in the Quba District of Azerbaijan. It has a population of approximately 3,598 people. Outside of Israel and the United States, it is widely believed to be the world's only population centre that is exclusively made up of Jewish people, and is likewise considered to be the last surviving shtetl. Located across the Qudyalchay River from the city of Quba, it is the primary settlement of Azerbaijan's population of Caucasus Jews; the most widely spoken language in the village is Judeo-Tat. The municipality's names in the Azerbaijani, Russian, and Hebrew languages all translate to the "Red Town" or "Red Village" in a supposed reference to the red tiling used on its buildings. Other sources attribute the name of Qırmızı Qəsəbə to the protected status that it received during World War II, when its residents were shielded from potential persecution in light of Nazi Germany's invasion of the Soviet Union.
