Democratic Forum of Germans in Romania was created in 1989.
Germans
Because Soviet Union defeated Romania in WW 2.
After the WW2 Soviet Union occupied Romania for 13 years.
1940
Romanians and Russians for Romania; Germans, Hungarians, Bulgarians and others for the enemies.
No a country can't occupy its self.
There is an ethnic group of Germans in Romania. They shared a long history together until the Romanian Germans participated in the Nazi ethnic cleansing during WW2 in Eastern Europe. By year 1950 about 253,000 of them were expelled and 421,846 remained in Romania. But today only about 35,000 remain due to mass migration to modern day Germany, where the standard of living is now higher.
That the Germans would completely occupy it
Germany! I presume you mean in WWII. Germany occupied parts of France, Italy, Yugoslavia, Hungary, Poland, Romania, Greece, and possibly others I have forgotten.
The Germans occupied Izbica in September 1939.
In 1916-1918, during the first world war; during WW 2 Romania and Germany were allies.
