100 in European years
Shut up, Denmark. You waited longer to give Iceland independence and you still got Greenland and the Faroe Islands (though neither is fighting for full independence at the moment).
But this is the extremely high price you have to pay for being an independent nation who's doing pretty well for itself: You will be teased mercilessly by your Nordic buddies.
Congratulations Finland. May it be several hundred more years.

Europeans make fun of Americans for thinking 100 years is a long time.
