Research analyst Kalli Raptis in her book "Nagorno-Karabakh and the Eurasian Transport Corridor" wrote: "'In July 1918, the First Armenian Assembly of Nagorno Karabakh declared the region self-governing and created a national Council and government. In August 1919, the Karabakh national Council entered into a provisional treaty arrangement with the Azerbaijani government in order to avoid military conflict with a superior adversary'. Azerbaijan's violation of the treaty culminated in March 1920 with the massacre of the Armenians of Nagorno-Karabakh's capital, Shushi (called Shusha by the Azerbaijanis)".
