Rudolph J. Rummel estimated that from 1900 to 1923, various Turkish regimes killed from 3,500,000 to over 4,300,000 Armenians, Greeks, and Assyrians. Rummel estimates that 440,000 Armenian civilians and 264,000 Greek civilians were killed by Turkish forces during the Turkish War of Independence between 1919 and 1922. However, he also gives the figures in his study of between 1.428 to 4.388 million dead of whom 2.781 millions were Armenian, Greek, Nestorians, Turks, Circassians and others, in line 488. British historian and journalist Arnold J. Toynbee stated that when he toured the region he saw numerous Greek villages that had been burned to the ground. Toynbee also stated that the Turkish troops had clearly, individually and deliberately, burned down each house in these villages, pouring petrol on them and taking care to ensure that they were totally destroyed. There were massacres throughout 1920–23, the period of the Turkish War of Independence, especially of Armenians in the East and the South, and against the Greeks in the Black Sea Region.
