The Government of National Unity was a Nazi-backed puppet government of Hungary, which ruled the German-occupied Kingdom of Hungary during the Second World War in eastern Europe. After the joint coup d’état with which the Nazis and the Arrow Cross Party overthrew the government of the Regent of Hungary, Miklós Horthy, the Arrow Cross Party established the coalition Government of National Unity on 16 October 1944.

A puppet state, puppet régime, puppet government or dummy government is a state that is de jure independent but de facto completely dependent upon an outside power and subject to its orders. Puppet states have nominal sovereignty, except that a foreign power effectively exercises control through economic or military support. By leaving a local government in existence the outside power evades all responsibility, while at the same time successfully paralysing the local government they tolerate.
