That changed at midnight on Sunday, 18 March 1944, with the invasion of Hungary by Nazi Germany, and the arrival in Budapest of SS-Obersturmbannführer Adolf Eichmann to oversee the deportation of the country's Jews to the Auschwitz concentration camp in German-occupied Poland. From 5 April, Jews over the age of six had to wear a 10 x 10 cm (3.8 x 3.8 in) yellow badge on the upper-left side of their coats or jackets. Jews had to declare the value of their property, and were forbidden from moving home, travelling, owning cars or radios, listening to foreign radio stations, or using the telephone. Jewish authors could no longer be published, their books were removed from libraries, and Jewish civil servants, journalists and lawyers were sacked.
