In the final year of World War I, Nakhchivan was the scene of more bloodshed between Armenians and Azerbaijanis, who both laid claim to the area. By 1914, the Armenian population had decreased slightly to 40% while the Azeri population increased to roughly 60%.[2] After the February Revolution, the region was under the authority of the Special Transcaucasian Committee of the Russian Provisional Government and subsequently of the short-lived Transcaucasian Democratic Federative Republic. When the TDFR was dissolved in May 1918, Nakhchivan, Nagorno-Karabakh, Zangezur (today the Armenian province of Syunik), and Qazakh were heavily contested between the newly formed and short-lived states of the Democratic Republic of Armenia (DRA) and the Azerbaijan Democratic Republic (ADR).
