In prehistoric times, a land bridge joined Alaska to Asia where the Bering Strait now lies. Across this bridge, most archeologists believe, came Asiatic peoples—ancestors of the Indians—who migrated to the North and South American continents 12,000 to 14,000 years ago. Probably 8,000 to 5,000 years ago the ancestors of the Eskimos and the Aleuts also crossed the land bridge to Alaska. The European discovery of Alaska did not come until the 18th century.
President Jefferson sent a couple of his representatives over to France to buy the city of New Orleans. What he got was the Louisiana Purchase, a patch of land that nearly doubled the size of the young nation.
Ancestors of the American Indian were in what is now Minnesota by the late glacial period, some 10,000 or more years ago.
