Input: Question: Approximately how many people died in the massacares at the end of the Russian Revolution? Passage:During the Russian Revolution of 1905, conflict erupted between the Armenians and the Azeris, culminating in the Armenian-Tatar massacres. 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 was at 40% while the Azeri population increased to roughly 60%. 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 First Republic of Armenia and the Azerbaijan Democratic Republic (ADR). In June 1918, the region came under Ottoman occupation. Under the terms of the Armistice of Mudros, the Ottomans agreed to pull their troops out of the Transcaucasus to make way for the forthcoming British military presence.
