At the Paris Peace Conference in 1919-20, the losses inflicted on the first Armenian state (the Armenian Democratic Republic) during the Armenian Genocide and between 1894 and 1923 were calculated. It amounted to more than 21 million French francs (Western Armenia – 15,000,000,000, and Eastern Armenia – 6,000,000,000), which is around 3.5 trillion dollars.
Below is a map of modern Azerbaijan on which you can see the ethnic population between 1100 and 1880. The ethnic cleansing (Genocide) of the eastern Armenians took place in these territories, which subsequently contributed to the establishment of modern Azerbaijan.
In 1850, the population in this area was about 2,285,000 people, of which more than 60% were Armenians and 15% were Turkic people. And in 1920, after ethnic cleansing, the population was over 2,862,000, of which 70% were Muslims (Lezgins, Talysh, Iranians, Azerbaijanis (Tatars), and others) and over 25% were Armenians who were mainly situated in Artsakh, Nakhichevan, and Baku.
