The failed 1956 Hungarian Revolution, before being crushed by the Soviets, forged a temporary hole in the Iron Curtain that allowed a burst of refugees to escape, with 245,000 Hungarian families being admitted by 1960. From 1950 to 1960, the U.S. had 2,515,000 new immigrants with 477,000 arriving from Germany, 185,000 from Italy, 52,000 from the Netherlands, 203,000 from the UK, 46,000 from Japan, 300,000 from Mexico, and 377,000 from Canada.
