At the Lausanne Conference of 1922–1923, Turkish representatives repeated the version of Armenian history that had been developed during the war. The resulting Treaty of Lausanne annulled the previous Treaty of Sèvres which had mandated the prosecution of Ottoman war criminals and the restoration of property to Christian survivors. Instead, Lausanne granted impunity to all perpetrators. After the 1980 Turkish military coup, Turkey developed more institutionalized ways of countering genocide claims. In 1981, the foreign ministry established a dedicated office (İAGM) specifically to promote Turkey's view of the Armenian genocide. In 2001, a further centralization created the Committee to Coordinate the Struggle with the Baseless Genocide Claims (ASİMKK). The Institute for Armenian Research, a think tank which focuses exclusively on the Armenian issue, was created in 2001 following the French Parliament's recognition of the genocide. ASİMKK disbanded after the 2017 Turkish constitutional referendum.
