The existence of a independent fascist Slovakia or the German colonization project about it?
About the second one, I can quote directly by Wikipedia:
"Although the official policy of the Nazi regime was in favour of an independent Slovak state dependent on Germany and opposed to any annexations of Slovak territory,
Heinrich Himmler's
SS considered ambitious population policy options concerning the
German minority of Slovakia, which numbered circa 130,000 people.
[11] In 1940,
Günther Pancke, head of the SS
RuSHA ("Race and Settlement Office") undertook a study trip in Slovak lands where ethnic Germans were present, and reported to Himmler that the Slovak Germans were in danger of disappearing.
[11] Pancke recommended that action should be taken to fuse the racially valuable part of the Slovaks into the German minority and remove the Gypsy and Jewish populations.
[11] He stated that this would be possible by "excluding" the
Hungarian minority of the country, and by settling some 100,000 ethnic German families to Slovakia.
[11] The racial core of this Germanization policy was to be gained from the Hlinka Guard, which was to be further integrated into the SS in the near future.
[11]"
According to statistics, the First Slovak Republic had approximately two and a half million inhabitants. In 1950 the Hungarians were 10% of population, while Roma people were not counted. Almost 300 000 inhabitants, I guess, would have removed from Slovakia to be replaced by German families, so, if we considere German fertility plans, one hundred thousand means something near to a half a million of German settlers. Considering policies of assimilation, I can imagine easily Slovakia becoming a sort of colony, maybe with a only formal independence, but part of the Reich as Bohemia, Norway, Denmark, Sweden and Benelux. Slovakia was also a Clerical-Fascist Regime, strongly linked to a nationalist and anti-communist vision of Christian Catholicism, so it's probable a crackdown when Hitler will launch his crusade against Christianity: Hlinka Guard, the Slovakian branch of SS, will be put in power and will accelerate the assimilation process in the Great Reich.
