Today one could hardly believe that some parts of the United States were once colonized by the Russians. Russia had several colonial possessions in the Americas from 1733 to 1867. Settlements spanned parts of what are now the US states of California, Alaska, and two ports in Hawaii. The thing is that the two countries are divided by the Bering Strait. The Strait is about 51 mi wide at its narrowest point, so the Russians felt free to explore and colonize the territory of Alaska.


The Bering Strait. Now you see that the distance between the continents is quite small.
