The Tehcir Law (from tehcir, a word of Arabic origin in Ottoman Turkish and meaning "deportation" or "forced displacement" as defined by the Turkish Language Institute), or, officially by the Republic of Turkey, the "Sevk ve İskân Kanunu" (Relocation and Resettlement Law) was a law passed by the Ottoman Parliament on May 27, 1915 authorizing the deportation of the Ottoman Empire's Armenian population. The resettlement campaign resulted in the deaths of anywhere between 800,000 and over 1,800,000 civilians in what is commonly referred to as the Armenian Genocide. The bill was officially enacted on June 1, 1915 and expired on February 8, 1916.
The Tehcir Law was part of the "special measures" (declared in a euphemistic language) against the Armenian population taken by the Ottoman Empire during World War I. This was coupled with a second set of orders given to the "Special Organization" for systematic elimination of the evacuated population during the death marches, also including the alleged taking care of the vacated properties.
The Ottoman archives document that the Armenian deportations started as early as March 2, 1915.
After the expiration of the Tehcir Law, deportations and massacres still occurred. On September 13, 1915, the Ottoman parliament passed the "Temporary Law of Expropriation and Confiscation," stating that all property, including land, livestock, and homes belonging to Armenians, was to be confiscated by the Ottoman authorities.
Before the Ottoman parliament implemented the "Tehcir Law", there was a circular by Talaat Pasha. In the night of April 24, 1915, Mehmed Talaat Bey, who was the minister of interior at the time, ordered 250 Armenian intellectuals to be deported from Constantinople.
