I wonder if I am right in thinking how extraordinary the election of Nicolas Sarkozy really is. He is, to begin, the first president of France whose parents were not both born in France -- that is, he is the first child of an immigrant to become president.
But he is also, I believe, the first first-generation immigrant to be elected head of government of any major developed country, certainly since World War II....
I can't think of a German chancellor who was not of German origin -- excepting the Austrian colonel corporal. I can find no British prime minister who was not of British origin, no Italian PM who was not ethnically Italian, no Japanese who was not Japanese.
There have been, I think, no presidents of the United States who were born to immigrants, and only one VP: Spiro Agnew. (Michael Dukakis is the only first-generation immigrant even to be nominated for president that I can think of.) Ditto prime ministers of Canada, at least since Laurier (Macdonald and Mackenzie were both immigrant children, but in those days so were many English-speaking Canadians, if not most.)
Perhaps I've missed someone. Have any first-generation immigrants risen to head of government in any other major industrialized country? (The only one I can think of in any country, off the top of my head, is Alberto Fujimori of Peru, though there must surely be others.) Or is Sarkozy unique? And in France, of all places!
UPDATE: A couple of good catches in the comments. John Turner was indeed born in England to a British father, then emigrated with his Canadian-born mother (his father having died) back to Canada. And Bonar Law was born in Canada, then accompanied his Scottish aunt (his mother having died) on her return to Scotland. Both of these were arguably more in the nature of repatriations than immigration. UPPERDATE: And of course, Turner was never elected!
QS adds some good info as well, before wandering off into fantasyland...
