Royal Birth in Canada
 

but the government changed the nationality of the hospital room or something??

Well one of the dutch princesses (i believe margarete) was born in Canada during WWII.

That would be Princess Margriet of the Netherlands, the sister of Queen Beatrix. The Princess was born in Ottawa, Ontario, where the family had been living since June 1940 after the German occupation of the Netherlands. The Ottawa Civic Hospital on which Princess Margriet was born were placed temporarily outside the jurisdiction of Canadian law so that she would have exclusively Dutch, and not dual, nationality.

i see, thank you!!!

there was also the crown prince of yugoslavia. the hotel that his parents were staying in was changed so he could be born there. i believe the hotel was in the united states.

Crown Prince Alexander was born in London,UK.Same procedure was granted by PM Winston Churchill for the occasion,as was the case in Canada for the birth of Princess Margriet.
