In 1944, responding to the advancing Soviet forces, the Regent Miklós Horthy deposed the pro-German Prime Minister and installed a more balanced government in an effort to engage with the Allies and avoid occupation by the Soviet Union. Shortly afterward, German forces invaded Hungary, deposed Horthy as Regent, and installed a puppet regime led by Ferenc Szálasi of the anti-Semitic and pro-Nazi Arrow Cross Party. The Arrow Cross Party never abolished the Monarchy as a form of government, and Hungarian newspapers continued to refer to the country as the Kingdom of Hungary ("Magyar Királyság"), although "Magyarország" (Hungary) was used as an alternative. From May to June 1944, Hungarian authorities rapidly rounded up and transported hundreds of thousands of Hungarian Jews to Nazi concentration camps, where most died.
