Etel-Köz was the Szekely land of the Ugrian Közarig which was ruled by the Bulanids. It was established by the Akötziri "Huns" who remained there after Etel's son Csaba the Hun left for the Wild Fields in the 5th century. It fell under the rule of Edemen's Avar-Bulgars in the 6th century and was crushed by the Utigurs of his brother Ed from the Wild Fields. Hence it was ruled by Kubrat's Kubiars in the 7th century before Ed's Hungarians fled to the Dniestr (some even as far as the Volga) in the Kubiar civil war and Etel-Köz gained independence. In the 8th century its rulers converted to Judaism. Many of its Székely Közarig migrated westward leaving Közarig graves in Chelarevo and other Közarig traces in Crisana such as Satmar. Etel-Köz entered into a friendly alliance with the Hungarian Cowari of the Dniestr in the 9th century to liberate the Western Székely Közarig who had fallen under the rule of the Mojmirids. After helping the Hungarians settle in Pannonia, only a tiny remnant of Ugrians known as the Csangos remained behind in Moldavia where they were converted to Catholicism by the Cuman Diocese. Etel-Köz survived as an independent kingdom in alliance with Hungary until the 11th century but continued to be the main base for Székely Sabbatarians until it was flooded by Ceaușescu in 1989.
