Presidential Decree No. 071/1945 Coll. and No. 88/1945 Coll. authorized the Czechoslovak administration to draft people into paid labor service for the maximum period of one year in order to redress some of the war damages. Under the disguise of "labor recruiting", the deportation of Hungarians from South Slovakia began to the recently vacated Czech borderlands,. Those who could not prove that they either remained loyal to the Czechoslovakia during the war, or that they took part in liberation, or that they were subject to Nazi terror, also had their property confiscated under Presidential Decree No. 108/1945 Coll.. The transit trains were labelled as "voluntary agricultural workers". In fact, the real goal was to alter the ethnic composition of South Slovakia. These "labor recruitings" were named by Czech historian Karel Kaplan as "internal colonizations", and according to him their "political aim... was to transfer a part of the Hungarian minority away from the Hungarian border and to destroy it as a compact territorial unit. This colonization also had an immediate industrial goal - to provide the depopulated areas with a workforce". Between July and August 1946, under the slogan "Slovak agricultural labor assisting the Czech lands", more Hungarians were deported to Czech lands. Eventually, 40,000-45,000-50,000 Hungarians were deported to Czech territories recently cleared of Sudeten Germans, but also to the other areas where labor force was required. While their properties in Slovakia were confiscated, they obtained the former Sudeten Germans' properties. According to the Slovak National Archives, 41,666 Hungarians had been deported from southern Slovakia. Hungarians who stayed in Slovakia became the targets of the Slovak assimilation efforts.
