I found a strange footnote of history recently: While Canada and Austria fought each other in World War I, both interned Ukrainians from the Carpathian Mountains as enemy aliens / enemy sympathizers. The Canadians interned the people because they were technically Austrian nationals (and therefore enemy aliens) since their home region was ruled by Austria-Hungary. The Austrians imprisoned people from the same villages because they were allegedly Russian sympathizers and therefore not sufficiently loyal to the Austrian government.
For background, here is a description of Canadian internment camps, which included living in tents in arctic conditions while constructing park facilities in the Canadian Rockies:
Here is a description of the Austrian prison camp for Ukrainians during World War I:
Canadians and Austrians may have been at war, but they both agreed that Slavic peasants from the Carpathian Mountains could not be trusted and belonged in prison. History is very weird.
