toll ranging from 289,000 to 750,000. The figure of 750,000 is suggested by political scientist Adam Jones. Scholar Rudolph Rummel compiled various figures from several studies to estimate lower and higher bounds for the death toll between 1914 and 1923. He estimates that 84,000 Greeks were exterminated from 1914 to 1918, and 264,000 from 1919 to 1922. The total number reaching 347,000. Historian Constantine G. Hatzidimitriou writes that "loss of life among Anatolian Greeks during the WWI period and its aftermath was approximately 735,370". Erik Sjöberg states that "[a]ctivists tend to inflate the overall total of Ottoman Greek deaths" over what he considers "the cautious estimates between 300,000 to 700,000". Some contemporary sources claimed different death tolls. The Greek government collected figures together with the Patriarchate to claim that a total of one million people were massacred. A team of American researchers found in the early postwar period that the total number of Greeks killed may approach 900,000 people. Edward Hale Bierstadt, writing in 1924, stated that "According to official testimony, the Turks since 1914 have slaughtered in cold blood 1,500,000 Armenians, and 500,000 Greeks, men women and children, without the slightest provocation." On 4 November 1918, Emanuel Efendi, an Ottoman deputy of Aydin, criticised the ethnic cleansing of the previous government and reported that 550,000 Greeks had been killed in the coastal regions of Anatolia (including the Black Sea coast) and Aegean Islands during the deportations. According to various sources the Greek death toll in the Pontus region of Anatolia ranges from 300,000 to 360,000. Merrill D. Peterson cites the death toll of 360,000 for the Greeks of Pontus. According to George K. Valavanis, "The loss of human life among the Pontian Greeks, since the Great War (World War I) until March 1924, can be estimated at 353,000, as a result of murders, hangings, and from punishment, disease, and other hardships." Valavanis derived this figure from the 1922 record of the Central Pontian Council in Athens based on the Black Book of the Ecumenical Patriarchate, to which he adds "50,000 new martyrs", which "came to be included in the register by spring 1924". Aftermath Article 142 of the 1920 Treaty of Sèvres, prepared after the first World War, called the Turkish regime "terrorist" and contained provisions "to repair so far as possible the wrongs inflicted on individuals in the course of the massacres perpetrated in Turkey during the war."
